How To Build A Nested Faraday Cage - Protect your Electronics From An EMP

[@davidstephens4639]

Because of military strategy, plan on a second EMP several weeks after the first EMP. That's why you prepare backups for your backups.

[@trollking99]

Solar flares are unpredictable.

[@cherylperkins7538]

You betcha !!!!!

[@The_Privateer]

As always, appreciate your videos. A couple of observations - without some sort of connection between the conductive layers, you've potentially made a capacitor - layers of conductive material separated by a thin insulator. Back when I worked with No Such Agency and Tiny ElectroMagnetic Particles Emitting Secret Things (if you work it out, you'll get the snarky reference) we had decent results with fine copper screen, an air gap of a few millimeters, and a fine nickel screen. Regular steel screen also performed well instead of nickel but isn't corrosion resistant. Stainless steel wasn't as good since it loses a great deal of steel's ferromagnetic properties. Aluminum screen wasn't too good since it's paramagnetic. Without getting too science geeky, the point of the different metals is that copper is diamagnetic and nickel is ferromagnetic and helps to cancel some of the incoming waveforms with the way they interact with magnetic fields. Both the copper and nickel screen were attached to a common ground. Since the portions of the frequency range for an air burst EMP can be as high as 11 GHz or so (11 billion Hertz) commonly available metal screen with 1 mm or smaller gaps) should work fine. You want gaps no more than around 1/10th to 1/12 of the wavelength for an appreciable amount of attenuation to occur. Solid metal is always better than screen. The only real reason to use screen over solid sheet would be for things like ventilation or ease of working with it. The 'gaps' in RF shielding end up being 'tuned' to the wavelength of the emissions it 'blocks' (attenuates) or allows. The 'holes' in the screen you see in the window of your microwave, for example are small enough to effectively block RF in the 2500 MHz range and lower but allows higher frequencies through. Since the 11 GHz is significantly higher than the 2500-ish MHz (2.5 GHz) that frequency range will pass through a microwave relatively unimpeded. Additionally (man, this is getting long - sorry about that) corners and edges will act as 'hot spots' and can end up turning into antennas to essentially 'rebroadcast' the frequency you're trying to block. The closer you can get to a smooth sphere the better.

[@hobbyistprepper414]

believe even if a capacitor effect was created, it would be short lived. just don't touch anything til a day after the emp.

[@RealitySurvival]

+Hobbyist Prepper yep I agree.

[@gonyearanch6588]

Great video. For what it is worth, I worked as engineering manager at a plastic injection molding plant in the 80s (during the cold war) and we did lots of military work. We got a project from an Aerospace company to make new monitors for NASA mission control. We just made the plastic housing for the old style squarish monitors. Around 100 or less as I remember. They were required to be shielded for EMP. They told us how to do it. We sprayed the entire inside surfaces with nickel paint. The housings had vents for cooling. We outlined each of the vent holes with silver epoxy and then played copper mesh across the vent, on the inside so the silver epoxy was actually played on the previously applied nickel paint. That's it. Of course, they told us that the entire building was built with copper gauze covering the exterior.

[@RealitySurvival]

+Gonyea Ranch interesting!

[@wbvmcgary]

I am using nested ammo cans for my electronics with conductive tape to seal and connect the lid to the body to protect against higher frequency short wavelengths. There are some good arguments about whether or not to earth ground metal buildings sufficiently on all 4 corners, I grounded my shop/garage. My 20+years experience in working in electronics, communications and microwave leads me to believe grounding is necessary to dissipate the longer wavelengths that larger conductors like metal buildings will absorb and hopefully this(grounding) will provide better attenuation(sending the EMP currents to ground)of the EMP so vehicles don't sit there with the EMPs bouncing around inside the building searching for a earth ground source and creating more havoc. However the shorter waves should not be grounded but insulated from ground as they are straight line waves with nothing to bounce of of that suits their wavelength and should dissipate rapidly. The faraday cage as Mr. Johnson just showed you, and he did it right, should not be earth grounded IMHO. Microwave ovens used as a Faraday cage will indeed stop the longer wavelengths but not the higher frequency shorter ones. I do hope this helps. If the truth be known is that none of us have witnessed an electronic EMP so the outcome is at best sketchy and what measures to take are theory at best. We need some advise from the Military, they know what to do and exactly how to do it. I can guarantee that anything connected to the electric grid will be toast. So many theories and so little time. God Bless!

[@RealitySurvival]

+wbvmcgary that is what my research showed as well. Objects larger than a couple of feet in diameter for sure such as buildings should be grounded. Smaller objects under a couple of feet in size should not be. But there are a ton of different opinions on this issue and it seems to be the biggest divide on how to build them.

[@wbvmcgary]

We need to connect somehow with a few Military folks that work in this field. I have been out of the Military so long that my contacts are zero. I will go speak with the good folks here at our National Guard. May I recommend all others do the same and post their results. Real facts are out there, sometimes in our own backyard. I will be checking with our local N G. I intend to find factual answers and with my background I don't think I can be fooled. Teamwork folks, please do what you can to get facts. Do you know any current military that can hook you up with those that actually know this stuff??

[@RealitySurvival]

+wbvmcgary great idea and yes we should all do our own research for sure! On the military side im sure we will be disappointed though as more than 90% of military equipment is not protected.

[@wbvmcgary]

Hmmmm. That is brilliant of them, maybe there really is no such thing a military intelligence. Surely I can find someone that has first hand knowledge on EMP shielding beyond what I already know. Surely the military isn't the only source I can find. I'll work on it.

[@justAnotherMike82]

do not ground at multiple sites for a single circuit it can cause ground loop problems. see: en.wikipedia.org/wiki/Ground_loop_%28electricity%29 also a large conductive loop (grounded or not) can act as an antenna

[@politenessman3901]

I realize that this was a demonstration of protecting against EMP, but if you are packaging up your electronics like this, I'd suggest throwing in one or two of those dessicant packages to pull any moisture out of the sealed air - you wouldn't want to unpack your gear after an event and find it corroded.

[@RealitySurvival]

+Politenessman sure. Great idea. Couldn't hurt at all!

[@uekidude2460]

Yes--Also, I place a straw in one corner of the zip-lock and zip over to it. After sucking out the air, I pull the straw out with my teeth. While doing this, I have the zipper pinched next to the straw with a thumb and index finger so that when I pull out the straw, I can instantly finish zipping that last bit.

[@sling4426]

thanks for the vid, I wonder if burying the devices under would help at all, no?

[@Kube_Dog]

Definite yes on the desiccants and straw method. I DIY desiccants out of silica gel cat litter (big bag for about $5 at Walmart) and tea bags, so I never have to skimp on that. I over-desiccant everything. Except when using O2 absorbers for food. They actually need some moisture to work right, so no desiccants.

[@Kube_Dog]

The tape isn't contacting the metallic material. There's a gap where the sticky part is. Only a mm or less gap, but there's no contact.

[@constitutionalqrf1713]

I did something very similar with my preps. I used a vacuum sealer instead of plastic bags, in order to "press" the heavy duty grilling foil a little better. then insulated with cardboard outside. then another foil-vacuum seal-cardboard layer. then cut the exact same bags you used into pieces and basically "giftwrapped" the package using purpose made EMP tape. Then insulated a 5 gal can with cardboard that had a metal "constricting" ring all made of ferrous metal sealed again with the EMP tape between the bucket and lid, but under the ring.

[@MrLawOrderPrepper]

I appreciate this video! It’s very informative and instructional! A few years ago, I built my Faraday Cage almost exactly like yours but I failed to cover my electronics in that extra layer of copper mesh... Oh well, I guess hindsight is 20/20, huh? LoL Anyway, I built my faraday cage out of an old 2 drawer file cabinet... I lined the inside compartments with extra cardboard and plastic and sealed EVERY crevice, crack, and opening with that 3M metal tape... I hope this works! Keep up the good work!

[@LAPGOCHINSTRUCTOR]

As a Radio and Electronics Engineer, i recommend all you need to do to protect your equipment is to place all of your electronic gadgets in a sealed metal container. This can be a large metal tool box that has a metal lid/top. If for some reason you need a much larger container such as a garden shed to store various electric and electronic systems, you can use your copper wire mesh to provide a screen to outside EMP interference. I have seen Faraday cages made of copper mesh and wooden or metal frames made into a large square box.inside of a building. Inside the Faraday box engineers worked on paging equipment without any external interference. The box was made up of 6 sides of 10 feet x 6 feed sides/top and bottom. Every side top and bottom panel was electrically tied together [ a wire link connection each side of the box] and the door on one side has an electrical wire link so when the door was closed all sides of the box and door were electrically linked.There was no requirement for secondary protection - such as the plastic bags, duct taoe and tin foil..

[@RealitySurvival]

[@leatherneckprepper4477]

I am an electrical engineer and let me say their are still plenty of things that baffle me in my very field. Keep up with your great work.

[@RealitySurvival]

+DB Cooper thanks for watching!

[@PowderMill]

I hear you Sir. I’m an EE with a focus on microwave spectrum. My main focus has been public safety communication development and design of P25 interoperability between disparate agency systems. As far as EMP…? I Am LOST! 🫣🤣. Researching the DHS and DOD programs and projects attempting to make military and critical infrastructure EMP “proof” (aka “resilience” because who’s gonna be around to apologize if their strategies have failed). The BEST engineer / EMP “expert” is Dr. Alan Bradley. He has a KZbin channel but I can’t recall the name. He was the first person to show testing that was somewhat legitimate. (He used a spectrum analyzer in his homemade faraday cage devices). He also nailed the probability of the frequency range being right above 70cm in the mid UHF range. Many others are showing testing using all sorts of snake oil. Good Luck and God Bless!

[@seminolerick6845]

A step up, and multipurpose tool is a vacuum sealer. Electronics, foods, ammo... endless uses. I bought a used med grade unit... it does as many in a row sealings I want, vs cheap units need to cool down after a couple. I learned a little late to include a reseal bag, so once vac seal broken... extra bag will protect unused portions. The seal bags ARE pricey, so watch for sales !

[@davidjodoin3433]

Hi, I'm Rachel, and your video was great! I saw a documentary years ago on emp pulses, and faraday cages, and prepping Air Force one. At the time I thought my electronics were screwed, but you've given me hope. Thank you!!! Does the steel can have to be galvanized? How about a steel diaper pail ? If you bury a item 6 ft. Down do you still need to protect it? Plastic condensates with weather changes , so I would use a desiccant . You can get silica gel at a craft store.... it's used for drying flowers, and can be reactivated by putting it in the oven on low heat on a cookie sheet. You could put it in a cotton pouch, or wrap in paper. Tin foil rips easily, can I wrap the metal tape around the whole item? How about aerospace bags instead of zip locks? You can suck the air out of them.i use them for everything! Thanks !!!!

[@dorianforces116]

protect it even still if its 6ft in the ground. Also, if you wrapped it and can still call the phone it's not gonna work

[@wjf213]

That's one radio that will NEVER been seen or used again. Now all you have to do, is do ALL THAT to the nearest radio station so when an EMP hits, they can still play your favorite 70's and 80's rock and you can listen to them on your radio. Seriously though, that does look like a great way to protect your electronics. I'd do handle helds with battery chargers and then batteries in another separate package that I can get to easier and keep tabs on every year or two. I think I'd also keep some stuff wrapped up in case there was a second attack say a month later or something, just to make sure all the stragglers and anything that made it through the first strike, would be taken out by a second strike down the road. Like they say, two is one and one is none. Keep up the great work.

[@RealitySurvival]

+wjf213 lol. Thanks for watching. Good stuff!

[@TomPapatolis]

Put a smartphone into your packaging. Call it. If it rings you have done nothing.

[@RealitySurvival]

+Tom Papatolis unfortunately that only works in one respect. The EM wave is about 73,000 times stronger than a cell signal. So if it rings yes you need more protection but if it doesn’t that still doesn’t necessarily mean that it is protected.

I've been prepping since 2012 full time. I work with my hands for a living. My problem is I can't afford all the things I need for this and that. How are you doing it? Can you make a video on that? Thanks

[@RealitySurvival]

Pretty simple. I make youtube videos and have a blog and use the money from both for my preps. Which in turn goes back into the channel and website helping them to grow. Plus As a part of doing gear reviews I get to keep any gear that I review. But I do also have a pretty solid income but I try not to ever dip into that unless absolutely needed.

[@seminolerick6845]

Buy a little ea paycheck. I do some food, some gear, some liquid . Prioritize in purchases... needed most NOW, affordable etc. Piggy bank for very expensive items to buy when enuf saved up. Good luck !

[@davidstephens4639]

By the time I bought my DriShield 3400 anti-static bags, my 3M 1126 tape, and my 3M 1170 tape I was in $200. Add in a couple of new galvanized cans and a couple of ham radios brought it over $500. Plus the automotive electronics, I'm nearing a grand.

[@paengineer1956]

[@RealitySurvival]

+Norman Osburn thanks!

[@richardrobertson1331]

Great video with a fine collection of follow-up comments, and I’d like to propose three points. My understanding of the purpose of “protecting” items in a Faraday cage is two fold: First, to keep the EMP’s massive shower of charged particles away from sensitive life forms and electronic equipment and, second, to shield away the induced magnetic field caused by this massive flow of electrons. So, it seems counter productive to ground the cage. Grounding just invites more electrons to flow thru the cage shell, similar to a grounded lightning rod. Considering only the electron flow, the cage can be made of anything that supports electron flow, such as aluminum, copper, silver, etc. That leads to my second point. Whenever electrons flow, an induced magnetic field is generated at a 90 degree angle to the electron flow and that magnetic field needs to be diverted or kept “outside” the cage, as much as possible. So, with respect to protecting electronics from exposure to this induced magnetic field, that limits the Faraday cage construction material to basically four elements, listed in decreasing order of effectiveness: iron, nickel, cobalt and manganese (and the thicker the better). The third point I’d like to make and have everyone consider is the problem of induced Gamma ray radiation known as the Bremsstrahlung Effect when the EMP’s intense shower of charged particles interact with the nucleus of the atoms of Faraday cage material.

[@RealitySurvival]

Yep grounding is not good on small cages.

[@Aresfire2]

In military aircraft all avionics are built surrounded by a Faraday cage then they are all bonded (grounded) to the airframe which is also a Faraday Cage which has a copper mesh embedded in layers thru every part of the airframe which is made of composite materials for nuclear combat ...

[@RealitySurvival]

+Aresfire2 thanks for sharing!

[@subaerialman1577]

This method will work.Its overkill.The reason for the mesh is to arrest pulsed fields and the mesh cannot be touching the radio,so a heavy plastic bag is enough. I use an ammo can,I file the edge free of paint that contacts the rubber seal.Line the can with cardboard or foam,put the radio in a plastic bag,or wrap in a rag.Add another item in the can the same way.Before you close the lid, put TWO layers of HD aluminum foil over the top(cut to fit with 1 inch hangover).Close the lid and the foil seals it electrically.Now its up to you if you want to ground the case of the can, personally I don't because stray pulses travel through the ground too.The big ammo cans hold a lot of stuff and they are waterproof too.Hope this helps.

[@RealitySurvival]

+Subaerialman good stuff!

[@johnnorwood507]

Love your channel but I think you have gone above and beyond. The best book to help one understand E.M.P's is written by Dr. William R. Graham. The book is Black out wars. You will discover that the best way to protect any and all electronic items is simply to use a metal trash can with a tight lid and wrap the items that are going into the trash can with a 50 gallon industrial trash bag so the items do not make contact with inside of trash can. Simple and very cheap!!! I advise all to read his book, have a blessed day.

[@cherylperkins7538]

You MUST have a proper seal though. Even I know that. If not sealed well it could leak. !!

[@thomaswhitten2537]

Well, dude, it may or may not stop an EMP pulse but I can guarantee you it's not going to get wet!! Ground the whole thing or place in a container that can be grounded and you've done pretty much the best anyone could ask for. :) Good Job!

[@RealitySurvival]

+Thomas Whitten Thanks. The grounding rule is a contentious one. The best research I found suggested not grounding small objects under 2 ft by 2ft because the ground wire will act as an antennae and actually bring in more em energy than it would without it. But all the research suggests that larger items should be well grounded.

[@davidstephens4639]

Because of Starfish Prime, MIL-spec for EMI shielding is 80 dB. But as proven last summer on the USS Fitzgerald, we can generate more now. As a sponge can get saturated with water, our atmosphere can get saturated with EMI. This seems to be around 300 dB. The DriShield 3400 is worth 50 dB, the 3M 1126 is worth 85 dB, the aluminum foil is worth 40+ dB, the sealed galvanized is worth 40+ dB. I forgot what stainless is worth. I couldn't afford to incorporate a layer of stainless.

[@johnchalinder6682]

The singular drawback of this is that, when the item is wrapped this way, you can't use it. So, if there's an emp pulse while you're using your equipment, it's toast. I suppose it's a great way to protect items that you keep in reserve just for post-emp usage. For everyday use items, the ideal situation would be to emp shield your entire house. And don't forget to shield your vehicle(s), too.

[@RealitySurvival]

Yep just the backups get wrapped.

[@deangullberry5148]

No idea what DoD doctrine is these days, but in the '90's were told analogue devices would be fine, as long as they were isolated from a power source (unplugged or batteries removed). Digital equipment needed to be faraday protected, or EMP hardened, regardless of whether or not they were connected to their power source.

[@RealitySurvival]

+Dean Gullberry yeah there are a lot of varying ideas on what will and what won't be effected. No clear consensus for sure.

[@deangullberry5148]

Reality Survival, no doubt. I just wish someone that has actually gotten some legit research would tell We the People something. I (probably foolishly) hope that the info given to the military is worth a flip. I do put a little stock in the idea, since the presidential nuke plane is all old school analogue.

[@anakin0405]

doesn't matter if it's analog or digital, if it has electrical components in it, it will be affected

[@revelation1235]

Would stored, unused solar panels be affected?

[@RealitySurvival]

If they were not in a faraday cage it is likely that the diode in them would be blown out at a minimum.

[@davidstephens4639]

You'll want a 36 yard roll of 3M 1126 per project, an inch wide, and an 18 yard roll of 3M 1170. Put your electronic device in a DriShield 3400 bag, seal with 1170. Put in another 3400, seal with more 1170. Put all that in the smallest possible cardboard box, even if you have to cut and tape. Then wrap that in the 1126. Then another layer of cardboard before a layer of common kitchen aluminum foil, shiny side out. Tape all the seams with 1170. Then if you can put that in an airtight stainless steel enclosure. Either way, put the whole thing in a new, cardboard lined galvanized can, then tape around the perimeter of the lid with 1170.

[@charleswas0419]

In the case of a nuclear attack at least you and your family can have an amazing game of pass the parcel afterwards.

[@RealitySurvival]

Lol.

[@rickgreen4449]

one last thing the Compton effect is still an em pulse just the direction and means of its creation are stripping electrons and sending them along the mag field. So it is in general the em we are looking for. It is a current producing electric field. Which is what the cage is built to absorb. ref wikipedia

[@RealitySurvival]

+rick Green thanks for watching!

[@doughook4287]

You might want to think about adding a label on the outside of the wrap so you know what's in all those layers. Just a thought.

[@RealitySurvival]

Great idea!

[@127ice]

An EMP is like a fast, short lived, very strong magnet. When the lines of force move past wires (Induction), a current is induced in the circuit, and because the device was not built to carry that much current, your little radio gets fried. The EMP would really fry an electric fence cable because it is insulated, but disconnect both ends from the shocker unit and nothing will happen because the wires are not connected to a load. The Copper screen is non magnetic, the tape and the Anti-Static bags are Aluminum. Aluminum is non magnetic. Don't believe me? Put some Aluminum foil over a magnet, then put something magnetic (I.E: Steel) over the foil. Fold and double that foil many times. You will see that the magnetism isn't affected by the foil in the least. That EMP Pulse will also get through that Aluminum. You MUST use a magnetic material like Steel, Tin, etc. These magnetic materials will collect and dissipate the magnetic lines of force. As to that little tape player....it is totally vulnerable. Try to find some rolls of tape that are attracted to a magnet. Get some magnetic screen too.

[@RealitySurvival]

+Harry Nelson thanks for sharing your opinion!

[@bennelson942]

I'd suggest labeling the package. I'd hate to have to open all that up just to figure out what I put in there.

[@RealitySurvival]

+Ben Nelson If I am opening any of it, I will likely be opening all of it. But labeling could not hurt. :)

[@davidstephens4639]

It is a capacitor, but after the EMP, toss a wrench at the can to let any residual surface charge dissipate to ground. Careful how you open it as there may be more residual charges at each layer. Using jumper cables to a metal rod in the ground may prove helpful, but research so you don't end up hurting yourself

[@sulu758]

[@derekaduncan]

Very informative vid...I would have to wrap my bunker with plastic wrap, copper mesh aluminum foil to protect for EMP burst or there is a simpler method to protect a wider area?

[@themessenger6442]

Plastic is a no no. Go to harbor freight and get them rubber tool box pads and cut to fit then add a cardboard or wood line then chicken wire. Instead of plastic you would be better off with Mylar. Mylar is also very good for evasion tactics, tent lining , heat protection for winter, ect.

[@RealitySurvival]

+Gerald Key Sr. thanks for offering your thoughts. Unfortunately it os not consistent with my research. Perhaps your mileage varies.

[@BigFootWalker]

Thank you, thank you, thank you for showing how to build a better Faraday cage. I was just going to line the metal garbage can with 2 or 3 layers of cardboard, then put everything inside. I really like the idea of wrapping each item in their own min Faraday cage, then placing the mini's inside the larger Faraday cage. Looks really good to me. Thanks for the video.

[@RealitySurvival]

+BigFootWalker1776 you are very welcome! Glad you found it helpful!

[@markfischer3626]

I think your design is very effective. Two suggestions. I'd have used copper foil instead of copper mesh. If you were not inside a metal building which is presumably grounded, the outermost conductive layer should be grounded. This can be done simply using a three prong plug. Run a wire from the ground pin to the outermost conductive layer and plug it into any three prong receptacle. You can learn about the defense departments research by searching operation Starfish Prime on KZbin. In this experiment run in July 1962 a 1.2 megaton hydrogen bomb was launched using a Thor rocket and detonated 400 kilometers above the earth about 900 miles southwest of Hawaii. The EMP was sensed as far away as Australia, India, and San Francisco. Note there were no widespread reports of damage including to the electronic sensing and monitoring equipment nor to any of the ships electrical equipment. The test by North Korea was one tenth the yield of Starfish Prime. The greatest risk may be to low earth orbit satellites and other communications equipment. DOD has taken steps to create secure communications systems in the event of an attack. In the event of a solar Corona mass ejection hitting earth, if is large enough no protection would be sufficient except perhaps deep underground.

[@RealitySurvival]

+Mark Fischer good stuff! Yep copper foil would be great!

[@heathergomes3552]

Is received using a electronic specific static electricity bag as a posed to the ziplock bags, but all in all it seems good.

[@andrewfawcett5353]

In a SHTF / EMP situation you get to play a game of pass the parcel to see who wins the radio. Do not forget to label each parcel as you don't want somebody thinking its a boil in the bag MRE. It would look fine that you went to all that trouble wrapping that radio only to find that all the radio stations got wiped out so nobody will be broadcasting anything. LOL

[@RealitySurvival]

+Andrew Fawcett lol. For sure. That is why it is a shortwave so you can pick up stations from very long distances. :)

[@dh0614dh]

Go a step further... If you have a transceiver; you can transmit. Hopefully others will be looking for a signal and find yours... Or you can stay silent and listen....

[@davidstephens4639]

I suggest you do 2 ham radios in separate enclosures, then do all the following for each car you wish to save. It will have to be an older American car or pickup with a carbureted v8. You'll need a digital multimeter, an analog multimeter, a timing light, a spare alternator, a spare voltage regulator, and a spare ignition module unless you resort to a points distributor. I chose both. Both modules and distributors.

[@Mountainrock70]

If this major EMP attack goes down you wont be going anywhere. The EMP would be followed by a major nuclear strike.

[@RealitySurvival]

Not likely.

[@drnv150]

Wondering if you could test by using a 12 kv neon sign transformer with a step-up tesla coil, up to a few million volts, but low current, we used to make 6 foot tall tesla coil in high school electronics class that could arc several feet at about 30 million volts, very small current.

[@sulu758]

Of course, I'm not worried about emp so much as Solar storms.

[@RealitySurvival]

Solar storm is more probable.

[@raykarl2119]

If you use a can like yours, make sure that the handle brackets do not go through into the inside of the can. Some of the cheaper cans do that.

[@RealitySurvival]

+Ray karl good stuff! Thanks.

[@survivaljulia9861]

Can you wrap a file cabinet in this and put your electronics In the file cabinet without wrapping the devices? How about vacuum sealing the item with 5 mm plastic? Would it matter if there was a little air in the ziplock bag . Those faraday bags look like 5mm Mylar bags I do my food storage in. I wonder if I could use the Mylar bags as last layer if I can’t get the faraday bags for final step. The other thing about the Mylar is you don’t have the plastic zipper, you can heat iron them shut.

[@byates59]

Dang, that radio is not only protected from an EMP, from bullets and bombs as well LOL AWESOME video bud! Thanks!

[@drewspykerboer4139]

[@RealitySurvival]

No doubt! Good call

[@Faithfulfamily]

Thanks for this video. I think I’m going to try this with a filing cabinet :)

[@HBJ5483]

I have only been awake to the prep world for about 1 year now but, my question is, if we possibly get hit with an emp,....with the electronics we protect, who would we contact or communicate with or listen to if the power is out everywhere? What are the long term advantages of protecting our electronics? Sorry in advance if this is a dumb question, but I was always taught the only dumb question is the question not asked.....

[@RealitySurvival]

+Harry B Loc'd no worries. I will do a video response to answer this as I have had a few people ask the same question.

[@faerieSAALE]

There's an EMP attack and then there's a Neutron Bomb attack that kills every living thing but leaves buildings and infrastructure intact. Imagine if both were used. Something to think about isn't it. The Neutron Bomb [ theory ] hasn't actually been built or tested - YET - but it doesn't mean that out of desperation the enemy wouldn't do it. WAR! What are they good for? Absolutely nothing!!! Huh, good god y`all... Next is the day you try to use your electronics. Let's say you hear voices and make contact with a group or agency and they say Hello to you. You're thrilled of course and immediately what to talk to others out there. You tell them where you are and how many of you have survived the calamity. They ask if you have enough to eat and any weapons to protect yourself. You reveal you're sitting pretty at a survival camp or maybe in your basement. They continue to chat with you day in and out - until - two dozen well-armed and trained individuals show up at your place and attack you from all sides... you lose and die. They then plunder and take everything for themselves. THIS IS WHY YOU LISTEN ONLY AND DO NOT SEND OUT ANY SIGNALS OR MESSAGES FOR MONTHS. YOU KEEP QUIET AND KEEP YOUR HEAD DOWN AND STAY OUT OF SIGHT. WAIT - WATCH - LISTEN - STAY DARK - STAY QUIET - STAY ALIVE. Good Luck

[@RealitySurvival]

First your understanding of a neutron bomb is flawed. They do exist. They have a lessor blast effect but it still destroys buildings but they have a higher penetrative radiation to be able to penetrate the armor of tanks. Also there is no harm in speaking to people just use good opsec. Don’t be silly enough to tell people where you are or that you have food and supplies. Also only talk in short bursts not for long conversations so that you can’t be triangulated.

[@mraleksk1]

Packing $10 radio into $100+ wrapping materials, a very sound financial idea.

[@RealitySurvival]

+Alex Karlov I think it was about a $70 radio. But i will be putting multiple other items in there as well. So yes it is a sound idea. Money well spent if an emp ever happens.

[@deserthorizons]

.+Alex Karlov...true,, but how much would a working radio be worth after an EMP.?

[@RealitySurvival]

+deserthorizons if it is shortwave a metric crap ton!

[@lucyswannsunsafespace7313]

Reality Survival "a metric crap ton" = my new favorite scientific measurement! 😂 Honestly, I think it's worth every penny, as all that money you may have in the bank won't be worth shit if an emp hits. Working short waves are priceless after that. Just as long as you're stocking food as well.

[@RicardoRMedina]

After an EMP attack that $10.00 radio is going to be worth its weight in gold as there will not be many of them working.

[@axelbob1]

Would you have to put your solar powered generator in the faraday cage to prevent harm?

[@RealitySurvival]

Yes most likely.

[@jenwilliamsintl]

Thanks for the invaluable information and demonstration. I had never heard of a faraday cage before. QUESTION: How can we protect our electronics from an EMP using faraday cages when we have to use our computers, phones, etc. daily for work, school, business etc. EMPs would be a sudden blackout without a headsup to wrap up. Please explain...thanks!

[@RealitySurvival]

Great question! Here is the answer: What Survival and Prepping Items Should Go In A Faraday Cagekzbin.info/www/bejne/bYjSeqJ-oJyMjKc

[@jenwilliamsintl]

Reality Survival & Prepping Will check it out. Thanks for the super prompt reply!

[@jenwilliamsintl]

Also, when you get a chance, please listen to my two "Prep" messages: www.blogtalkradio.com/jenwilliamsintl

[@randallperkinsky]

i mean, phones to make calls after a emp attack are not gonna work as all the towers will be trash. the main use for computers would only be if you had important info stored on them like books etc. you could take a cheap laptop. and a external hard-drive. load it full of stuff and pack it away for such an event. Most useful items will be radios, ham radios. medical equipment. survival items etc.

[@rickgreen4449]

Well i have looked at the basic information and one seemingly over suggested site was saying that it was not necessary to ground and that the line for the ground could be used as an antenna. I do think that is a true statement knowing that the signal will normally seek ground when it can and knowing that any difference in potential will send the signal to the least resistant path I can not see that the grounding is negated by a true mitigating factor. The true fact is that any wave when striking a conductive material will induce something in that object. So the only way to prevent that signal from reaching the interior is grounding or counting on the metal to provide a path around the interior material and hope that the signal does not saturate the exterior allowing the signal to influence the electronics inside. So without a ground on the outside when saturated by the signal it allows penetration to occur and leakage is the result which is looking for something to lead it to ground. Now I know that shielding of materials using a conductive layer and a non conductive layer without a ground is taking the chance that the conductive layer can handle all the signal and not saturate, this is the Idea I am hearing. Because if the exterior is saturated and the interior is saturated then the gear is toast. Well it is always better to send the signal to ground which in general prevents saturation and if it does leak the secondary cage is the backup as it takes the signal straight to ground there is no other path for it to go as anything in the cage is a resistance to ground and easy is the only way electrons like to move add resistance and it will if possible find another way. All of the reports indicate that the length of cable is a major contributing factor of emps performance but what seems to be missing in the report is the insulator damage and its cause. Ceramic insulators were destroyed on many electrical line poles, that is significant to note. It means that while seeking ground the signal used the pole as the means to ground. There can be no other explanation. It cannot be the detonation and it most certainly was insulated and operational before the detonation. Only when you put material as a resistance to the signal that contains such a high voltage can you arc through a resistance that high. it was noted in Russia and Hawaii. Same problem both places. So it used the pole, that in itself is a good indicator of the need for grounding. The point is that if you think that the flux from the signal is going to pass by the gear because you have mesh around it you are assuming that saturation cannot occur. Both the e1 and e2 are em fields and other radiation is not part of the problem since they do not emit a signal that can effect directly the electronics. I think the information was known to us and that we were set up in order to prevent this occurrence in our gear. I will expand the cage information to give you a better understanding of the shield since I think it maybe another reason why the equipment was safe. This gear was shielded on a common ground and the gear was equipped with a one eighth inch thick steel panel also grounded but unlike the interior cage it had no ventilation holes as the cage did and when closed the cage was fully encapsulated by it. Now this bunch of gear was important to the mission and there were many like it within the facility. I at this point can only say that the reason for the grounding wire to be negated is to my thinking not a reasonable choice given that it takes the signal straight to ground. once there it cannot do anything to the gear. I cannot find at least tonight that there is a reasonable explanation for not grounding even the guy who made the statements used a large mesh barrier on top of a carport and grounded it using a long wire admitted that it greatly attenuated the microwave signal in the tower above. Anyway have a good evening I just wanted to put in my two cents.

[@RealitySurvival]

+rick Green thanks for continuing to share your thoughts. We will just have to agree to disagree. Dont worry many electrical engineers fall on your side of the argument. It is a hard thing to get your head around. If you want to ground be my guest. But dont blame me if your stuff gets fried. :)

[@rickgreen4449]

It's no issue with me I don't blame you everyone is an expert so you should follow what you know as best. Which is what I always do. Thanks for the note. Rick

[@rickgreen4449]

Well I maintained in the field communication gear for the group that shared our mobile units. I think melded with good training and lots of experience with a large variety of gear I expect I can run a ground and I will employ what I learned to the task but I hope that you don't find out that I am correct. I hope you have a good design and it works. You know you can do a very basic test with am and FM radio. I assume you know because you likely read the material I did. If I find or stumble across any definitive data I'll pass it on so neither one of us has a bunch of inoperable equipment. No one likes that. Chow Rick

[@RealitySurvival]

+rick Green sounds good man!

[@jasonvanner3976]

I may be way off but from my understanding the statement you made about different materials working better/worse against different frequencies is true in a way but not really necessary. It's like saying metal is better than wood at dispersing the EMF. The frequency can be displayed as a sin wave. ( 🔊〰〰〰〰 ) bad example. Then, whatever the frequency is has to be smaller than the space of material used to construct the cage to pass through the cage. Ex. Aluminum foil is a solid surface with no holes (to the naked eye) so no frequency should be able to pass through it. I do believe thickness is a requirement. Ex. 2. A person can use chicken wire, fence, chain mail, or any conductive surface. Let's use metal fencing for this example. If a person were to wrap their entire room in fence material and make a box out of it. Meaning, fence material on top, sides, and bottom with no area that is not covered in fencing and then connected to a ground rod run into the ground 8ft for example (just a general idea). Now the frequency has an amplitude depending on the frequency. If you have a graphing calculator you can graph f(t)=sin(t) and the amplitude will be the height of the wave. Now graph g(t) =6sin(t) and the amplitude will be 6 times higher. Basically, amplitude = sin wave height. If the amplitude of the frequency of the EMP is smaller than the spaces between the metal fencing then the EMP gets through the cage. If the amplitude (wave) is bigger than the space in the metal fencing the metal fencing will absorb the EMP and disperse the energy around whatever is inside the box and the energy will then go into the ground. That was my basic understanding of faraday cages. A solid thick metal box would be the most effective. Solid- no waves can pass through. Thick - can handle more energy (??) Metal - is a better conductor than wood. Is this correct or was my thinking all wrong? Sorry for the long example. I was thinking that the type of material only played a part in the conductive abilities and the frequency was the amplitude (solid better than fence). Thanks for any feedback

[@RealitySurvival]

+Jason Vanner thanks for sharing your thoughts!

[@jasonvanner3976]

Reality Survival anytime, I thought it was an interesting video and I learned something new. I wasn't trying to say you were wrong or anything. I was just trying to explain it how I understood it to be. I'm no professor though lol

[@michaelfishermanny]

Test your faraday cages with cell phone and fm radio. Crank it up and then seal it up. if you hear it. its not working. Cell Phone for High Frequencies and FM for Lower Frequencies. I suggest a steel barrel with removable seal / band, wire brush it for electrical connectivity. and jumper cable it to a ground rod.

[@RealitySurvival]

That is a basic level test but the amplitude of an HEMP is about 70,000 times stronger. So it gives you an idea but is not really a full test.

[@judiththompson2423]

The sticky wrap also comes in a freezer version which is thicker.

[@tberry7348]

Lol, it's just a thick mylar bag that's been remarketted as emp bag. Don't get me wrong love The concept it's similar to something I would have come up with. I believe you said at one point, you said your method was probably Overkill and I would agree. Mylar is plastic/metal/plastic so I would have done the molar bag first then wrapped that in copper then insulated that. I wouldn't use anything flammable in the construction so I would trade out the carpet for fireproof blown insulation. And I would ground the steel can. If I was truly going for over kill I would line the trashcan in lead and then in high temp ceramic tile like those used in fire places. Running enough current threw steel will make it red hot. Just The way I would do it. As a note if I had a feraday room, for instance an electricly grounded metal shed then I wouldn't feel the need to ground the trashcan.

[@RealitySurvival]

Thanks for sharing your thoughts!

[@patb9375]

You could use a vacuum sealer to get the plastic sealed tight... Should wear gloves with the copper wire mesh and the tape. fold your aluminum foil ends up as you go to seal it up, first roll of foil wrap ends up next wrap take ends down... Did you think about throwing a desiccant pack in to keep it dry? There are metal cans with hard plastic liners you can get also.

[@RealitySurvival]

Great ideas!

[@jamesjohnson6239]

would a pickup bed tool box work ad a faraday cage ? large capacity weatherproof ,just line the in side and wala ,you could storr a chainsaw ,generator other large emergency items ,what do you think?

[@RealitySurvival]

I think it would work pretty well. You would just need to remove the weather seal around the lid and then tape up any holes and the lid with conductive metal tape.

[@jeecee8283]

For a 'true' Faraday Cage, each layer needs a wire to attach to a valid earth ground to conduct the pulse away from your device. Your use of different materiel is a good idea. :)

[@RealitySurvival]

+Jee Cee the community is divided on grounding. Most of the best sources I could find said grounding was detrimental on smaller items but needed on larger ones.

[@jeecee8283]

I was unaware. When I used to build antenna systems, I would use faraday construction with the antenna cables to prevent crosstalk of the different signals. Military construction uses faraday techniques when hardening avionic radio/radiometric equipment. Most radios are approximately the size of a Blu-Ray player. At the least, your separate layers of different conductors should be conjoined by 1 conductor to prevent capacitance ( as pointed out in an earlier post); especially if you do not ground the enclosure. I hope this helps :)

[@jeecee8283]

FYI: I was an avionics technician/instructor with the USAF/USAFReserve for 20+ years.

[@RealitySurvival]

+Jee Cee sweet. Thanks for your service! You prolly know all too well how most military equipment is not hardened against emps at all then. :)

[@RealitySurvival]

+Jee Cee thanks for watching!

[@driversteve9345]

If an EMP attack were to actually occur, I would wait a few days before taking your stuff out of your faraday cages. Whoever attacks us, might not send just one EMP attack but multiple over the span of several days! So think about that also!

[@RealitySurvival]

Thanks for watching!

[@disrespectz]

My recommendation for your can you do be bonding straps from your bucket lid to your bucket, and finally a form of static discharge from the whole bucket. You never know if there will be potentially hazardous static charges on the bucket. But wow impressive

[@RealitySurvival]

+Hugo Romero you bet!!

[@ScottyM1959]

JJ This is a great idea and maybe for one device but if I'm not mistaken it only takes minutes for a warhead designated for EMP from any of our nuclear foes. trying to wrap all of your necessary electronics for a family of 4 or more before we're "struck" seems futile this way. couldn't a faraday box built similarly with multiple layers with all layer's having continuity and just putting your electronics in the box be as good? Also, couldn't you cage around your studio/workshop there in your "metal building and have a faraday room? P.S. Now that N Korea has something that our tech people say can hit Alaska maybe the West coast do you still think an EMP is still not possible?

[@RealitySurvival]

+ScottyM1959 the idea would be that you wrap up all of the items beforehand. Because as you mentioned you will never be able to know if or when the HEMP would be detonated.

[@RealitySurvival]

+ScottyM1959 no I don't think NK has the ability to reach or strike the US. Japan is about the best they can do reliably.

[@ScottyM1959]

Reality Survival okay so I shouldn't put faith when the goverment "experts" that say the altitude these hit could drop one on Alaska?

[@RealitySurvival]

+ScottyM1959 Fake news. Lol. No I don't know for sure but for me it is not something I worry about.

Enjoyed... Seems every time I start anything to do with EMP / Faraday, I get overwhelmed with idea "This is probably overkill" and costing me money for other preps.... I heard you say it more than once, so at least the voices in my head are still sane... LOL

[@BumbleBeeJunction]

The carpet is not a waste JJ... An ozone generator works by producing an arch through a ceramic plate... The arch (think lightening) is what produces the ozone (also why it smells so clean after a lightening storm)... Anyway, the power to produce an arch multiplies exponentially with distance - even if that's all the carpet buys you...

[@RealitySurvival]

[@RealitySurvival]

[@ryandavis4689]

That very well may be overkill, but better safe than sorry bc most of us don't know for sure the true outcome. I have a few motorcycles in a "Faraday garage", basically a all metal cage with concrete and wooden floors (plus rubber tires)... Grounds on all four sides(times 2).ifk if a waste or would work... Hopefully won't have to find out. Better safe than sorry I reckon.. Edit: there is metal on floor under concrete and wood Edit 2: I thought of it during video but forgot, as the next comment says.... I do suggest connections between components... Think about it. Energy(no matter the form) converts, never deconstructs... It must always flow thru the easiest path.

[@RealitySurvival]

+Ryan Davis thanks for watching!

[@danniehopkins6650]

Question, if you can answer: How long does it last? My mom was watching a video on it and it said that the waves would last 100 days. True or no?

[@RealitySurvival]

Are you asking how long will the effects of the EMP last? If so indefinitely. Or until about 3 to 5 years until the grid could be repair in the best case scenario. However it is more likely that it would take decades to fully recover. If ever.

[@peterdambier]

There is a lot of paranoia inside your can but in the case of an EMP that comes from the sun, from Saturn, from Jupiter or some 20 stars arround us ... nobody knows for sure and paranoia does not hurt. You absolutely need that carpet inside your can. That was missing from the other packages. An X-ray event is radio but at a very high frequency, higher than light and very strong. Some lead bags for photographic films may help.Organic material like your carpet may help with some radiation.

[@RealitySurvival]

+Peter Dambier thanks for watching!

[@thehammerglock17]

Not related to the video, but what do you store for long term food storage, or what do you recommend. I'm looking at possibly starting the valley food subscription service where they send you freeze dried pouches once a month. Any considerations?

[@RealitySurvival]

+thehammerglock17 Valley is good. Numanna is good. Legacy is good. The Ready Store can be good if you get it at 60% off or more. Wise and Mountain house are good as well but VERY over priced. I personally recommend buying from multiple vendors. This will give more variety and if you get a bad batch it will only be a small amount. Also I recommend keeping your pantry full of normal food and storing dry goods and canned goods in bulk as well.

[@thehammerglock17]

I haven't heard of numanna before, I'll have to check them out.. I have a few cases from the lds cannery because it's super affordable. But they are basically just dry ingredients and wouldn't be very enjoyable on there own. Hoping to find some good entree mixes to combine the noodles, rice, beans, and potatoes into to extend the entrees

[@RealitySurvival]

[@butchcass223]

If you owned a vacuum sealer from a bulk store of choice save some bags and bag potential air gaps? One outer airtight seal with other material of course around the target object? And of course a Mylar bag finish?

[@georgiebearpaws]

I've been thinking about this, it's all well and good to pack these small items away. But to come out ahead, people would need to make safe charge controllers, inverter's, a PC and monitor not to mention, most kitchen appliances have micro processors installed. I feel like, I need to have a "Faraday" room or closet at my house, if that was possible to do.

[@RealitySurvival]

+George P yep it is possible.

[@1johnmthompson]

I like your idea of different skins. I used a vacuum sealer on mine when i did mine but did multiple layers of aluminum foil then nested all the items in a 40mm ammo can as an additional skin. I had the same thoughts on the emp bags so i heat sealed the outside edge. Then used markers as a label device. Then took photos for my book so i would not wonder what was in the box; )

[@RealitySurvival]

+1johnmthompson excellent!

[@lomgshorts3]

Don't let the aluminum foil touch the copper anywhere. The two metals will generate a galvanic response together, and corrode where they touch. Otherwise, very well done!

[@RealitySurvival]

Yep that’s what you got to have that insulation layer.

[@Ryan-sl2oe]

Pretty sure that radio could survive a direct nuclear blast with that much wrapping.

[@RealitySurvival]

Lmao. Prolly so!

[@yankey4]

you can also use a microwave as a faraday cage. So if you put that in side a old one. Your going to be good. We use this and a old microwave to take care of are smaller solar parts. Like mppt charge controller and smaller inverts. God Bless brother,,

[@RealitySurvival]

+yankey4 read some of the other comments. Some folks address the short falls of microwaves better than i could. Thanks for watching!

[@gregkeel4155]

Would it be worth it to make a layer out of lead flashing ( the kind for roofs and windows) . I heard lead is good protection from radiation but don't know if it would do anything for an EMP

[@RealitySurvival]

+Greg KEEL since it is conductive i believe it would help to eliminate a portion of the frequency band. However I have not ever seen anything suggesting to use lead. But if you have it it prolly could not hurt.

[@leonbgc]

great vid good info most people just line the can with card board and toss their item in. what kind of blow gun do you have on your peg board I have similar ones my self

[@evemebufor313]

you missed a spot on the copper mesh.

[@RealitySurvival]

+evemebufor313 lol. Dang it!

[@ziggy-pn4ts]

I have a scooter, what if I took electronic parts of scooter and wrapped them with aluminum foil good . Would that work.

[@RealitySurvival]

Not unless you wrapped the whole scooter. Lol

[@markfillery1002]

the best way to think of emp is like a lighting strike all that current passes through you electrics and blows it.

[@RealitySurvival]

Yep but much much faster than lightening. So standard lightening protection will not protect your equipment.

[@markfillery1002]

i know, that was for the layman emp 2 is like lighting its emp 1 you got to worry about

[@markfillery1002]

emp would be great if you could control it you could get power without a plug

[@ILOVENJ00]

If I am using my cell phone and laptop for work all day, when will I have the time to package it like this? The EMP waves travel in nanoseconds with no prewarning.

[@RealitySurvival]

Nope. Watch my vid called “What goes in a faraday cage”

[@job3687]

With grid destroyed, there will be no radio, tv stations operating, no phone service, no internet, and batteries will probably expire before grid can be replaced. So is there really a need for such preparation. Perhaps reason why military does no prepping such as this, as someone mentioned earlier.

[@RealitySurvival]

+Jo Bostic yes actually there is a ton of reasons. Shortwave radio picks up international and ham stations. Great for intell gathering. Small portable radios would be great for small team comms. Flashlights. Yep. Batteries have a shelf life of 10 years now days. Rechargeable’s longer. Solar panel battery charger? Yes please. All of these would be super helpful at a grid collapse.

[@rickgreen4449]

Well the nested is in general the same as an air gap. Air and plastic and rubber are transparent to the em field it doesn't know that it is there and presents about the same resistance to transmissions. It is also is the medium that the em wave uses to move through and when it sees an antenna made at the proper wave length it sees it as the very best way to ground and uses it. Non conductive materials provide an air gap and that is important while some materials don't conduct the field they do provide resistance to travel of that field and the greater the thickness of the material the better the cage will work because it always wants the quick and easy way to ground. All of the flux will want to take the metal layers to ground and all of those grounds should be linked together. The anti static component bags are not very thick and the thicker the material the more flux it can retain and move to ground. There are materials that are better at doing all of the above and some that are not. Aluminium and copper and steel seem to be the obvious choice for the netting as they are already on the market. We were using materials specially made to prevent em fields and the materials were not allowed to be released however I know that mesh and other materials do a fair job in the field. From what I have seen the only big issue in your project is that you do not have grounding on each item. All of them should be given a ground line (in several places) leading to the exterior container and the exterior must also be grounded or it does not work. Grounding the interior and exterior are essential to success. The whole point is to allow the em to use the metal surrounding the package to provide an easier pathway to ground than through the parts in the packages can provide themselves. Without a ground it may not provide enough surface area to take the emf around the protected package. By providing the ground on each item you give it a quick way to ground and saturation is less likely going to be a problem. When the packages are without ground the mesh will only be used as an easier path around the air gap which in this case is the package, it might work but it is not the purpose of the cage to allow saturation it is the conduit or rerouting of the em to ground that effectively eliminates the emf. All electronics and their forces end when ground is found.

[@RealitySurvival]

+rick Green i hear what you are saying but from what i have read the em wave is not just seeking ground like electricity does. Because of the Compton effect it is traveling on and through everything not just seeking ground. If an em wave did seek ground in the same manner as electricity then it would not propagate such extreme distances as it does it would seek ground right at ground zero. But that is a very common misunderstanding and many people do share the same opinion. I dont happen to fall on that side of the debate personally. Thanks for sharing your opinions on the matter though! I appreciate it.

[@rickgreen4449]

if it is like a gamma ray or like one and continuing to pass through everything then why put mesh on it? if it is an em wave it starts somewhere and ends some where. if not then I cannot see how mesh or anything would stop the propagation or reroute the signal and even though radio waves and other types of wave forms are transmitted, they are transmitted in air and have no means to ground unless it strikes it. they have no inherent ability to do otherwise as they have only the power and direction of the transmitter and are without the ability to change direction unless they strike something within their path. so when an emp is released in the upper atmosphere it goes out like a rock in a pond. the waves go 360 degrees in every direction and it is like any other emf it seeks ground or easy travel so what is being done is a re route of that signal to ground and away form the the package. i will look up the effect you mentioned and see what it is to better discuss you method but if the grounding does not work then the mesh is useless as far as I can see in that application. What does it effect? How does it effect this waveform? is it a true emf or is it a radiation of some type that you can tell me? And is it a byproduct of nuclear or other type of base material? I served in intel for my last two years of service and SAC the previous 2 yrs. The methods of all were the same in hardening and prevention of emp and emission, transmission security. so I assume the data you have is newer and that I am outdated (no shit) so I will learn about what I am missing here. So the wave is like a micro wave thru a wave guide? I just cant see any other wave form damaging electronics unless it can use the circuit or can damage the package in some other way, sorry I am just trying to think here and it will all be answered through a little research so don't bother answering the post until I have done the work on my end. Rick

[@rickgreen4449]

By the way the signal is not seeking ground on its own it just moves out from the antenna and through the air in all directions the reason the grounding works is that its wave like a transformer wave to the secondary has emf potential when it hits the circuit board of the electronic device. Once entering the device voltage/current are then present due to its potential becoming a usable power within the circuit. So you have too much power headed to ground or across individual components when not grounded that causes the burn out of the board. Kind of like putting the full potential or more at various layers of the circuit and the individual components without the proper resistance or reduction to that incoming voltage are then destroyed. It only seeks ground because it is made to do so. It in reality is for the most part never finding it and dissipates without ever finding it. Transformers have at least 2 circuits the primary and the secondary and they are not actually touching each other. The emf is transferred from primary to secondary then to the circuit in this exact manner. We take a higher voltage reduce the wire size and turns to go from say from 120 vac to 10 vac. The voltage is transferred thru the air to the secondary never having entered the lower powered circuit directly. So the emp wave by passing thru the package stimulates the circuit but we are not grounding out the whole wave just the part that is in contact with the surrounding grid. It is like any emf wave in that it acts as the primary and the board is the secondary part of the transformer and we intercept the primary force before it can interact with the board. So I am not telling you that you can ground the entire signal only the signal that interacts with the cage or the circuit board it is then that ground becomes usable not before.

+rick Green think what you are failing to realize is that the ground is equally saturated with the EM wave throughout the duration of the pulse. So the damage is already done but the time the energy would be able to flow to ground. Bottomline line is that it just isn’t effective. Thanks for sharing your opinion though!

[@rickgreen4449]

Sorry an em field travels at the same speed and cannot saturate the earths surface. A pulse at the surface of the planet still could not totally saturate the surface because there are non conducting materials where the flux can but does not want to go and each flux line in a pulse cannot be in the same space as another line they repel each other as like fields repel on a magnet. Ground is the end of all things electrical and in the case of saturation then there would be no way for any cage to work. Saturation indicates nothing more can enter and the earth is too large of a surface area for it to be saturated by one explosion at that height. Plus anything that would saturate the earth will saturate everything on top too. Electricity moves at the speed of light so delay is not in the mix. but if unsaturated and (I vote for that) the pulse finding the metal ground will be the easier path by far. The damage is based upon the field strength or potential hitting the circuit board but with a proper cage the flux is directed to ground by the shielding material as it is taking the easy path instead of the air gap thru the circuit board and then to the opposite side of the mesh. That is the whole reason for the cage being there, its sole purpose is to channel the flux around the electronics by providing it an easy path to ground. I do kinda understand electronics and I know a little about magnetic fields and telecommunications and encryptographic systems. I worked in telecom and crypto in the Air Force. I worked in telecom for Honeywell information systems, I was the Technical Operations Manager of a computer company and managed both field and bench repair services, I have worked in the programmable logic field for 5 years as an Applications Engineer, I worked as a Product Engineer for Integrated Magnetics for 18 years and was the Manager of Aerospace and Defense for the Western US when I retired. I held the following positions in between being hired and retired. Senior Product Engineer, Project manager, Chief engineer and Program manager and during those years I have learned a lot. I am currently waiting for a patent approval while having attained the patent pending approval notification and publishing of the patent by the US patent office. My first patent was for the non invasive glucose test machine. I made the power supply rotors on the F-22 and Joint strike Fighter and the timing assembly for the engine on the JSF. I have made assemblies for the Space station, Pioneer, and Hubble. These mean little to this project as I admit I am out of date on the tech and the brief but I am a quick learner and avid researcher. If you are willing to look at the various points you brought up and we can verify both mine and your information I would be happy to change my position as I am only seeking to find the truth not start an argument. I was only conveying what I have learned and done with my own hands so I will leave it to you, thanks for the conversation I do appreciate your effort to help us all in this struggle to care for our families during the days ahead. Hope to see you there (in heaven)or in the air. Rick, your brother in Christ

You protected your radio but will there be ANY radio stations transmitting after an EMP?

[@RealitySurvival]

+Russ Hart its a shortwave radio. It picks up signals from around the world.

[@oniswolsey433]

I wished I had money like he has to do that, must be nice to be so well off to be able to put one more layer just to be safe.

[@RealitySurvival]

Aluminum foil is pretty cheap.

[@faerieSAALE]

For continued added protection - take insulated can - place in wooden concrete mold making sure can is suspended and not touching sides, bottom or top, fill with concrete mix. Let harden. Remove the form. Next, place the concrete block in a lead-lined box that is soldered shut. Then bury six feet into the ground. AND THAT OUGHT TO DO IT! 😁 LOL... if you can't laugh at it - then you're way too serious.

[@RealitySurvival]

You are funny… but wrong. lol. Now that is funny.

[@youmaus]

I am going to have to agree with cryptocognomen, I think you have inadvertently created a capacitor which will pass the electrical energy easily a long as the voltage is in a varying flux. Capacitors in old tube radios were manufactured by making a sandwich of tin foil and wax paper which was folded and rolled then dipped in crayon wax. An effective Faraday cage needs space between it and the object being shielded, sort of like an airplane hanger. Your multiple layered approach is good for covering your bases for the broad spectrum of EMF, but each layer requires more space to be effective and not pass the energy by varying voltage capacitance.

[@youmaus]

As I am thinking about this, you could probably get away with the materials you have selected as long as you used spacers. These spacers might be something as simple as checkers from a checker board or other commonly available things like what are used in pizza delivery boxes to prevent the toppings from getting stuck to the box.

[@RealitySurvival]

+youmaus thanks for sharing your opinion. I have relied on experts in the field to come up with this so hopefully they know what they are doing but perhaps not! Only time will tell.

[@SweetLiberty001]

major big thumbs up. Thank you for that demonstration I am definitely going to apply it. The cost is not bad at all either.

[@RealitySurvival]

+Sweet Liberty glad it was helpful!

This reminds me of the kids in middle school who would wrap their egg in 50 layers then spend 50mins opening it and it would still be broken after doing the egg drop.

[@RealitySurvival]

Lol.
