The Wifi Umbrella Ultra long range Wifi

[@socrates_the_great6209]

Wow. That is an amazing performance for something, homemade, that even can be folded down.

[@rogerramjuice2562]

G’day Andrew. I remembered you spoke about ground planning. I have a 700-2700 MHz LPDA antenna. I had trouble getting it going again after a lightning storm. I pulled it apart to have a look at it and saw it wasn’t grounded. Once I did a closed loop and put it back together it worked better than when I bought it. I also reduced the cable length and crimped an SMA connector and it worked better than the day I bought it. Thanks for your expertise old mate.

[@andrewmcneil]

I will do a test outside sometime soon, when the wind dies down!

[@eyupa.1791]

andrew mcneil hi Mr Andrew. Thanks for all videos. I have a question please answer. I have an cheap panel antenna and it was not isolated between poles. Ground and signal were short circuit. Does it effect the signal quality and signal power? What is the important thing about isolation between poles? Thanks for now...(i isolated them witouth harming antenna design)

[@timplatts1199]

Could you simply use fewer panels to cut down on stitching. Even down to 2 if possible. Still use the fabric as a template. Perhaps reuse the original perimeter fabric as a tape edge with the ferrules still attached. Would be good to compare with this properly built one. Keep up to good work.

[@wj000]

@ Eyüp A. I heard that short between ground and signal in pannel antennas is a good thing, because it gives some protection to the radio. Without short excess electric charges can accumulate on the panel, especially during thunder strike and damage the radio. I noticed that more expensive antennas usually are shorted.

[@djmips]

Has the wind died down yet?

[@geoffreypotts5962]

The umbrella reflects alot (almost all) of the microwaves, since the holes are all smaller than ~1 cm which is (about) how large the wave is, the wave bounces off (almost) as well as solid metal.

[@cyberjack]

Military use something very similar for portable sat communications

[@amartini5168]

Last comment was 2 years ago but I'm adding to. haha. This is an awesome build! My aunt and uncle was c-Band installers when I was a kid and I've been infatuated with dishes and antennas every since! I have built several p2p kits with dishes and this is a great idea for testing! I'm going to try a build of my own! Thanks for the video!

[@andrewmcneil]

Your welcome

[@Migueldeservantes]

There is a very simple equation that allow you to find the full diameter of a sphere... if you use it you can much better situate the point of maximum gain ... increasing even more your signal strength...

[@haggar11]

What a fine work Andy. Great portable solution, Recently I have been thinking a lot of this combinations, I have used a 45CM portable camping dish, the return was also good with a 5GHZ cantenna. I would really be interesting to know how it would perform outside, I guess it would be over 100 access points. Thanks a lot Andy for the video.

[@jafinch78]

Awesome. Unremarkablely impressive.

[@beaconmania]

Nice job, as usual. thanks for sharing your time & experiences

[@OptionParty]

Center shaft could be made from an aluminum arrow body. Reflector could be made from Faraday Fabric, as it should be easier to cut/sew & fold up neater. The radial support rods will shadow very little signal, as the greatest signal will come from the parimeter of the parabolic reflector.

[@OldGamerNoob]

It's interesting that there were no results in the scan with low signal strength. I'm betting it has to do with the slight upward angle shooting over the head of any access point farther than a certain range. I wonder how many would show up if it were completely horizontal.

[@ronnieris1191]

great work keep going

[@vk3aqz]

Good experiment. Ingenuity plus! Cheers Andrew!

[@umairbinaamir3635]

Great modification. 💯✅👍

[@lmaoroflcopter]

What a brilliant idea!!! Looking for a portable long range antenna to perform some WiFi phishing on the job. This would be perfect for my kit. Much more portable than my Yagi.

[@ВикторБаклаков-у2ч]

Hello, please do a distance test on the same antennas, it is very important, your research will help both radio amateurs and rescuers and many others, the thing is really very useful.

[@guruoo]

Love your video, and great job on the antenna, Andrew. You certainly have more patience than I do. Mine's not nearly as portable, but years ago ('08, '09?) I purchased a metal snow disk, then mounted a wifi usb adapter in the focal point. Over the years, and through numerous dongle upgrades, Ii's come in handy in providing us with an alternative network connection when the cable's goes down. I live on a hill at appx. 100' above the average terrain, and today results show signal of literally hundreds of AP's, with good number of them open, and publicly accessible. Google: snow disk, flexible flyer, Round Metal Snow Sled.

[@ElPasoTubeAmps]

Andrew, I always enjoy your wifi antenna videos. You make some beautiful antennas. I couldn't help but comment here as I made what was was called a stressed-parabola antenna about 35 years ago to get a 2.4 GHz "premium" station that was new here in El Paso and I built this stressed-parabola as best I could, from plans from a radio amateur book. It turned out beautiful as can be seen in one of my videos where I show pictures of it but it did not work worth a hoot. After lots and lots of tinkering, I finally broke down and cut a template of a true parabola from cardboard and compared it to the shape of my antenna only to find the stressed-parabola was not a parabola at all. Like yourself, I spent hours sewing it together with small wire instead of thread. Just wondering if you know if the shape of your umbrella-parabola is actually a parabola. I think I remember going for a focal length to diameter ratio of around 0.6 (hoping to get lots of gain) which made my antenna pretty "flat" and a focal point way our front. Your idea of a shorter F/D ratio is probably a better idea. Actually, back at the time of my antenna, a snow dish (used to slide down snow covered hills) worked better than any other reflector I had at the time. You can see the pictures of my antenna at about 6:50 in this video. kzbin.info/www/bejne/fKu8eneCeZ2knaM Keep up the good work and stay safe.

[@joshuacoburn8140]

This is very very cool! Thanks for sharing! You might try tinkering with it by placing the transceiver antenna directly in the junction of the graduated cone waveguide, and the cylindrical portion of the waveguide, and you may get slightly better results by increasing the distance between the transceiver waveguide assembly and the parabola, and the cone portion of the waveguide might be modified by allowing for the angle of the cone portion to match the angle of the strongest rf focal point based upon it's distance from the parabola. It appears that you may get better results widening the angle of the cone slightly, and increasing the distance from the parabola, depending on how you choose to tune it. Excellent work on this! I really enjoyed your video! God bless you and your family. Keep studying, and keep tinkering! :*)

[@GospodinJean]

Great project. U know what would make it even cooler? Get some umbrella fabric. Sew those triangular patterns together. And sew end caps to the edges. But a bigger kind of end cap that would fit over the end caps already on the antenna. Then u could also use this umbrella as a funcional umbrella and therefore have a valid excuse for carrying it everywhere with you . (The real reason being not for preventing u from getting wet, but for the sake of science)

[@gammaprysem]

Perhaps try a metallic reflective "space" blanket?

[@LucasGarrow]

Nice! I'll have to try with WiFi Repeater with my bebop drone.

[@JohnjrtChicago]

Great job with this. Very enjoyable video. Keep up the great work. Thank you.

[@yadav.malleshyadav2363]

Bro i geven for u youtube servy 5 star rating for your channel,all the best

[@deanburgess8624]

Very nice work looking forward to making one myself. I noticed a lot of people saying just paint it or stick on aluminum foil however for a start the idea was to make it last for a very long time using either of them would loose quality over time plus catch a lot more wind outdoors

[@GospodinJean]

It reminds me of those moon rovers antennas

[@SimonShaws]

I think photography umbrellas do have a metallic material for the silvering?

[@cyberjack]

@@westleyleonstudios good point ..dont want it bowing down road..lol

[@OverlandOne]

This is genius!

[@freefilms10000]

well done

[@rixanneh18]

Absolutely epic

[@highflowhighflow9896]

Thats a pretty nice idea using a umbrella, never thought of that myself. nice if they are manufactory parabolic shape, wonder what the metal studs on the inner side have affect on the signal. maybe even plastic umbrellas can be found, would be better. i think the maze wide is tinny enough even for 5 ghz

[@honeybadgeractual5734]

hey, could you have glued the skeeto net to the fabric and have it all soldered together at the small ends to complete the circuit?

[@mikegravgaard340]

Good job.

[@andrevandermescht2370]

a Coople of stitches? What is coople? It should be Couple. What do you use for drinking Coffee? a Coop?

[@costi08]

What about gluing aluminium foil on umbrella material? Ideed looks better with mesh, but..

[@forfengeligfaen]

This is inspired! Did you choose the diameter of the holes in the mesh to work with the WiFi frequency? Have you tried it as a satellite dish with a DVB receiver?

[@PhonkElement]

you could put a second layer of that metal on there

[@dionisiojulaton4128]

Ohh sorry Andrew it's is not 229mm long it's 209 mm and 100 mm in diameter, pls teach me how to make a cantenna the correct distance from the back replector and what is the measurements of the driven element.

[@electronics.unmessed]

Crazy, but anyway nice. Looking forward to the test video,

[@tek5358]

trying this myself, so far so good, but folding those edges turns your finger tips into pin cushions, will update when i make significant progress.

[@Jonny10001]

I admire your patience Andrew! How about a 6GHZ SWR DIY bridge project.

[@nitrogencair4964]

Please give me the details of that horn feed system

[@fraserhardmetal7143]

Great mod - why not stick the mesh to the brolly - might save some time.

[@kayboku7281]

does anyone think the cantenna receiver bit seems way to close for that size parabola?

[@capoman1]

I wish in your testing you would show the db of a network before and after. I watch your videos and am interested, but without these numbers, I have no idea the performance.

[@socrates_the_great6209]

He forgot to say he picked mosquito net because the wind can just flow through your antenna. And he forgot to say what metal this mosquito net is made of. It may be improving the signal?

[@federicovisintini1619]

Nice job, guy! I'm looking to build a similar one for EUMETCAST. I'd have some questions about this kind of antenna... 1.st how did you find the focus of the antenna for a good allign with illuminator? 2.nd which fabric did you used for the dish? other questions will follow!!! Thanks for replies

[@tenlittleindians]

Somebody needs to get this product on the tv show Shark Tank so it can be mass produced. I think many people would buy them for camping or just for tapping into some free wifi they cannot currently reach!

[@ACTlVISION]

You can't patent this though

[@yxhankun]

I suspect the original reflector umbrella has similar receiving capacity as a mesh net parabola umbrella. Can u try that out? Please.

[@r66f80]

Can this be modified to pick up satellite TV signals, using the right kind of LNB?

[@HitEmUpru]

Hi Andrew, how i can contact with you? I have few question. I've write to you via twitter, but you didn't answered.

[@PaulPetrea]

Maybe here: kzbin.infoabout

[@eyupa.1791]

HitEmUp.ru he didnt answer me too.

[@tjja7321]

in the comments.

[@videounliker4101]

I saw a stick or pole antenna on the alpha network website with 15 dbi. Can you try to make one, because they are very omni-directional and very practical.

[@Andre-PY4DR]

Looking forward to seeing the outdoors tests... 73,s

[@socrates_the_great6209]

I have never seen mosquito nets in metal lol.

[@dionisiojulaton4128]

Hi Andrew your really amazed me. May you please teach me how to make a cantenna I don't know the correct measurements because the diameter is 100 mm and 229 mm long. And what is the measurements of the driven elements. Please kindly reply and thank you so much .

[@HometownUnicorn]

How would I go about using this to get a better 4g signal using my spare mobile phone or dongle?

[@stevec5000]

The umbrella had a silver coating on the inside before, wasn't that as good as the screen mesh? How much gain do you thing it has now?

[@TerryJonesPrinterRepairs]

did you test the original silver reflective paint to see if it was conductive? I wouldnt be surprised if it has a substantial amount of aluminium in it.

[@andrewmcneil]

Yes Terry it was not conductive

[@rossbrigolimusic]

You could have just painted the umbrella material with a conductive paint

[@davidlottering4001]

Grear video andy, what i wanted to find out is where can i buy your latest cantenna design, please send me a link.

[@gus452000]

Would this perform better with a helical antenna as a feed? Any thoughts? Being a deep dish I would suspect that you might need quite a few turns on the helical 5,6,7 or maybe 8? I would be very interested in the results and if it is better how many dB more would it be.

[@termination9353]

QUESTION - you said the parabolic/satellite dish [w/cantena] needs to be metal but aren't these common satellite dishes you see on rooftops (tv) some sort of plastic or fiberglass?

[@andrewmcneil]

You need a conductor (metal) with a fiberglass dish it is a laminate sandwich, two pieces of fiberglass with a aluminium filling

[@termination9353]

Thank you - perfect clarification.

[@charlien66]

I have a metal 100cm motorised satellite dish on my wall, mesh design.

[@Morbid1349]

Could this design be used for radio astronomy as well?

[@elcanaldelasabiduria9033]

hi andrew I habe a question... can you re-build the X wing antenna satcom, that is frecuenly uses for the band of 220~440 mhz sat comunnications and take it to make a very directional antena at 2.4 ?

[@pajapalala]

Hi sir, please make a tutor to up Signal LNB KU BAND or C BAND, sorry my english very bad, i hope you understand my mind

[@wildernessandme1744]

In making one of this should I focus the driven element or the reflector (of the cantenna)? Thanks.

[@eyupa.1791]

andrew mcneil Hi Mr. Andrew! Please reply. I really need an answer. I have an cheap panel antenna and it was not isolated between poles. Ground and signal were short circuit. Does it effect the signal quality and signal power? What is the important thing about isolation between poles? Thanks for now...(i isolated them witouth harming antenna design) Here it is: yadi.sk/i/UtWTqt7I3UrpiM

[@eyupa.1791]

Should it be isolated or non isolated? Which situation is give me best result?

[@davidlottering4001]

Hey andy just wanted to ask one more question, i have a friend who lives about 500m from my house he shared his wifi password with me but my antenna i bought off ebay cannot get a good connection, which antenna should i use to get a good connection to him and if i get onto my roof i do have a clear line of sight to his house

[@shukurkhaidr9854]

Hell nice i have a question does it work for long range FPV with different design or some thing else can you make one for Long Rang FPV OF different frequency

[@MariusBartkevicius]

Hi Andrew, Was following your channel for a while. What's do you reckon would be best DIY solution as external antenna for 4G (or LTE) internet modem? Mast station of 3UK (my internet provider) is 2.7 km in direct line from the place I live. Thank you in advance!

[@taiquangong9912]

How did you connect it to the can?

[@laroybafih]

Please make a wifi gun in 5ghz frek

[@jedics1]

Great but its so flimsy that it would be strictly for indoor use when really its an outdoor kind of thing.

[@Re_Kitty]

Do you have any estimate for what kind of gain this could have?

[@moonfestmadness]

what-about metallic paint :) plenty of products to play with :)

[@TWMist]

could you use staple's to connect the panels?

[@highflowhighflow9896]

hmm maybe tiny ty-wrap can be use too

[@dmaher2007]

Can any one tell me whats the best setup for a Motorhome WiFi system over a long range to pick up WiFi?

[@andrewmcneil]

if you have line of sight a cantenna for long range 2km. biquad for medium range. they are directional so both have to point to the source

[@dmaher2007]

I have tried him and still looking the video that was attached. Can anyone tell how to use to create a wifi receiver? I have the dish and this part, any help would be appreciated.
