You my friend just saved me around $100 US! I was just at Lowes pricing copper pipes tubes and rods for my own antenna. From what I'm seeing from the end of your video this will give me direct access to the AP I've been struggling to stay connected to. All for pennies on the dollar, and for a toilet brush can it looks a hell of a lot better than a 3 foot long monstrosity of copper piping!

Thank you for covering insulating the driven element from the rest of the Yagi. I prefer insulating the front parasitic elements also but have no proof that helps. Once out of the air, the wave propagates down the metal at the same speed. Hope you make a 5 Ghz cantenna as well. Cheers

I'm confused about the driven element. Is it a folded dipole? The short by the vias would seem to indicate so. But with center of BNC driving the center of the element, by symmetry, the current flows in opposite directions, and the fields should cancel. It doesn't seem right to me.

I bought one of those joke yagi's your holding @00:50, at the time I thought I was doing something wrong with it. I installed a wireless IP Security Cam system around a lady's house, 12 camera's. She also wanted one down at her big 2 car garage (had a living quarters above) which was roughly 300-350ft (90-105 meters), with a clear LOS. whole system was based off the home's wireless router, I used a pair of the ol classic WRT series linksys wireless 54G's (fastest @ the time). setting up as an AP... that bloody garage camera was the biggest pain in the.... I went from stock antenna to a bigger pair of -11dB (on both router&AP) caught a drift of an image for about 30 seconds, then poof.... SO I bought from fleaBay, that very same shiny stick you're holding there @:50, aimed& roof mounted it,....there, for hours, me the roof became one,.. I was better off with the higher db internal dipoles. Keep in mind, I had no clue back then about wireless sigs, rf in the gigahertz range, antenna types, wave length's, resonance freq, etc I was an old school tv antenna guy just learning about computer networking ;) Solved the dilemma very painfully.....ran a buried cat7 drop out to garage...lmao, I wish I knew then what I know now....d'ohhhh

Hello, very interesting and well documented presentation, I gonna test your wifican antenna ! My pov about your realisation : - Black paint is not a good candidat because it increase the temp in the can and increase the thermal noise never a good for signal noise ratio. The best paint are shiny white paint (never use mat) this is the same raison that you must never wall outside an house with mat paint. - Take care about bnc connectors they could be very problematic and increase loose and noise or buy expensive connector certifié for your work frequency; for this reason every as soon as possible i always solder directly the wifi dongle (or SDR dongle ) directly on pcb with a shortest low noise wire and put dongle in metalic grounded box. This make some differents with sdr dongle. - If refer to pratical antenna handbook (the holy antenna bible) with an air core in your case plexiglass this kind of antenna must be less sensitv to "Electrical vector" than with a copper or Aluminium, it could be interesting to compare the 2 case copper VS air core antenna. - Have you be able to test with a vector analyser (minivna & co) ? Thanks

Question, if you had to transmit 2.4 and or 5.8 wifi from one building to another over 10miles apart like me in setting up long range mesh network, what antenna would you use and please dont just say dish lol as thats expensive and stands out a lot! id like to try and be somewhat discreet as i may likely be using clients roofs and they would not like an isaw on the roof. Could a patch antenna do the job, perhaps stacked patch like the larhe one you opend up which was printed on a pcb but i dont understand how that works as it is not an active array and i was led to believe during my time in the army as a rad-op that you cant just add in another ant. So how do those stacked antennas allow for additional yagis/ patch antennas etc to use one cable and not increase power??? Really hope you understand what im asking and that you reply to this, i will look to find such a video you have done and comment there just incase you dont quite follow. Thanks again.

I'm curious, how the distance between the upper and lower elements affects gain. If you used two sheets of Perspex for spacing would it be better or worse. Is There an optimum spacing between upper and lower? I once had a long distance between my antenna and computer, I was afraid of the coax losses. So I disassembled a wifi dongle cut the antenna and mounted an N connector to match the N connector on my Yagi. I connected the wifi dongle directly to the Yagi. Then ran usb cable to my computer. It worked great, I used that for many years. It was all mounted on a boat in a marina. Also, it looks like there are only two lengths of foil, please post the lengths as printers often change the original size. Then I would make a quick template to cut the all.

If I were to make the can slightly conical would that have the effect of slightly 'opening up' the signal. I would like to utilize the antenna for use with a UAV using an automatic following system but your comment on the cantenna being extremely sensitive would preclude it from being used because of the slight delay in the 'following' system may cause the signal to be lost. I have seen several posts here asking for dimensions of the template, could you please advise the distance between the first and second element in order to ensure correct scaling.

I'm looking in to methods of extending WIFI and internet connectivity from the main house about 500 ft/150m to a second building on my property, and researching Yagi prototyping before buying hardware for the second bldg. I have a large amount of scrap materials to use for this project, but I don't really understand the physics at work here to know what to use. How does the diameter and spacing of the elements effect the waves, and what is needed for 2.4 Ghz standard WIFI? is there wiggle-room, or is it very specific? Also, would I need to do anything to the router at the main house, or should the Yagi at the second building pick up the signal inside without a problem? Thanks for the content!

Andrew, in "The Wifi Gun Does it Really Work?" you said that shorting the reflector to the active element (center to braid) would cause harm to the active equipment - agreed, and reduce efficiency, also agreed. Yet you have done just this, shorting centre to braid since the two sides of the aerial are connected by the vias. I was anticipating the braid being connected to the can/reflector. Am I missing something?

Pretty neat. I wonder, the plastic lid you put in front of the antenna to close it up and make it look neat, will likely introduce some RF loss. The lowest RF loss material you could use there is styro foam (mostly known and used as packing material) as it has very low density, RF goes right through it. Also in speaking of RF losses, the plexi glass material you used, might also introduce RF losses, perhaps comparable to using just FR4 circuit board material. For testing your antennas, you might want to consider getting a NanoVNA - about 150 Dollar on ebay. Then you can actually tune for maximum performance.

Hi Andrew, great job on your videos on antennas. I was planning to build a 10 or 15 element Biquad Yagi similar to your previous design. After seeing your new antenna design, I have a few questions-ideas that your answers-insight would be most appreciated. Here goes :- 1. How does this antenna perform compared to your previous Biquad Yagi? 2. Would the Biquad Yagi provide similar performance with wider beam width? 3. How about a double Biquad Yagi? 4. Would re-positioning the yagi element at 1/4 or 1/2 wavelength inside the cantenna make a difference? 5. How about a Biquad Yagi Cantenna Thanks. Looking forward to your next video.

Negative. You cannot use a USB cable to connect to the antenna. The antenna requires a coaxial cable that has a center conductor and an outer conductor/shield. The center conductor transmits the RF signal to the driven element while the outer conductor is the ground connection (in this case, the completed circuit connection for the driven element).The USB is a universal serial bus connector and is used for an entirely different purpose.

Hey Andrew, This makes me wonder if one could make stained glass decorations that would also be wi-fi antennas? Obviously I don't mean a 'yagi' style, but a a mere basic wi-fi booster mayhaps? Stained glass workers use this copper tape to line the edges of glass before soldering together...I think it would be dead brilliant to make decorational wi-fi boosters. windows or not they'd still look cool & as long as they're made properly, they could hang virtually anywhere...minding the critical info for reception of course.

Instead of laying this on a flat plane like your perspex, could you possibly put it on a curved surface like a clear fluorescent tube cover or would that mess with the waveform?

So, if this works, it's just dumb luck since there is no matching from the balanced driver (ie the yagi) to the unbalanced load (ie, the co-axial connection to the router ...

Can you please enable printing or downloading for the antenna template on google drive? Is it also possible to just use the yagi without the surrounding can? I want to use the antenna for travels when the hotel wifi is bad and i need to reach some other distant public hotspot.

Cu strips easily damaged while transporting. Scratch a strip and it's all over red rover. I would used large pvc water piping which solves ll the grounding probs and screw or push lids are bought off the shelf. All: Instead of asking thoughtless questions of Andrew, do your own research and learn something along the way. Sheesh!

Great design for indoor use. Don't use it outside though - rain on the tube will wreck the gain.

I would say just lay the copper tape on the plexiglass oversize then trim the ends to the template with a steel straight edge. You will get them deadly accurate like this and no fingerprints under the tape.

Well, the template is not secure because printer can shrink or expanded. I'm assuming you calculated the yagi for 2450Mhz, right? I'll use my yagi calculator to calculate the lenghs my self

Hi Andrew, will a standard aluminum foil tape work as substitute in place of the copper tape? Thanks! Great video. Very informative. EDIT: Sorry I made a comment before halfway of this video. I see I can use aluminium foil. (smh) I was too excited for this DIY project. UPDATE: Another question. Does it need to be transparent for the board that holds the elements? Thanks!

wire yes. pvc is non conductive and thus will not (for the most part) affect/direct the signal. dialectric (non conductive) materials can and do play an important role in signal propigation. so pvc = no if you want the same performance characteristics
