Andrew has definitely has been a pioneer in building diy antenna, I honestly can not find anyone like him let's hope he stays strong and continue to produce great work for us novice :)
Thank you for explaining how its done and being more specific with the laws of physics. Most people who post videos on how to make these type of antennas don't explain much of how they work.
Thank you again and I love your channel!
its not a gun, it's the mcneil wifi cannon
Thanks for the trick of using steel wool for cleaning super glue. Andrew, could you please tell me what is the gain diffrence between using the round disk over the rectangular type disks Sir ??? Thanks fella too.
Where have you learned all that information on building antennas ?? Would you be kind enough to give up your secrets Andrew ??? Thanks again.
this antenna can use for gsm or anything too good signal and stability u guys can try popular on russian..
Hi Andrew, thanks for your reply. My main concern with the thickness element difference was the change in frequency for the best SWR being lower than desirable.
Can an antenna also be a work of art?
Yes,... ART that works.
yours are, ascetically and technically
can work for all
Art it is!
@@stevemacbr just a reminder on a molecular lever the waves ride on the surface of material you use, copper or silver. with that said try to polish the material as best you can and you will see the difference in less drop off and strong connectivity. I have an uncle that worked in nasa, he said they build there antenna in a clean room and the material is polished to a certain standard, just an fyi
high quality work from andrew, a lighthouse in the ocean of ignorance
Great design Andrew.
I am also curious as Dr. Honorable comment below; can you make a shorter version as a feed to a dish. Thanks.
You can but I would use no more than 2 parasitic elements
would a modified tv ariel to enhance lte 5g coverage?
Will the ariel outstide be effected by a weather cover in plastic?
What is the maximum co axeil cable needed?
Is there a maximum height advantage when mounting it on the house gable end ?
Is grounding the back plate as easey as wiring it into the metal mount screws on the house wall ?
Do you use the online web information to direct it to the nearest mast ?
Would you be able to use any other ferrious metal to make it from?
Could you make a normal omni directional vertical rod areil out of copper/plastic plumbing fittings from the diy shop ?
How to protect your WiFi card from lighting.....do this antenna attracts lighting,
The information you passed on here is really useful, thank-you.
You're very welcome!
Andrew can you try a shorter version as a feed to a dish ?
not worth it.. it's gonna be hard to fix and centralized.. go for panel would be much better and higher gain
Use a helical mounted to a parabolic dish. I found a Muzak sat dish for free that has supposedly good reception for sats, and I’m going to use it with a wifi and 5.8 ghz receiver on the mounting point, and try to make it mounted with stepper motors.
Won't the 21*0.5mm elements accumulate to 10.5mm in total length, throwing the spacing between the pars slightly off? Or is that a negligible difference?
what's the math involved please for something that would work and where would you put your elements? I loved to see a video as well. your version
Also would love a video on VNA vs Spectrum analyzer.
its a work of art .. looks beautiful
Thanks
Thanx a lot for the video! I really wonder which one has a better gain bi-quad yagi or this one? If they have a relatively similar performance which would be easier to make? Also, what do you think about patch yagi guns? There is a channel on youtube, in Russian, where one enthusiast makes such ones. the name is "Free wardriving". He also makes Batwing antennas that have a broader range of frequencies.
So is that antenna linearly polerised as in horiontal in the video. Do you think you would have picked up more WiFi AP's with it set to vertical polarisation? But nice project all the same. Oh for the insulation of the Driven element Transistor isolating washers may work. they are usually made of ptfe as well so would not melt in the sun. 👍
did the boom have any bend? because its so long, cant imagine it being totaly straight, does it matter it not being totally straight ?
You are just more than amaizing. I am learning from you and of course you are trusted person. Thak you sir ❤
Simply fantastic, id very much like to see what you could do with up to date videos, with such range you can detect signals and perhaps connect to an open wifi access point but would you receive data from the access point as the transmitting access point antenna is tiny and the signal may be good with this ant but the receiving strength surely would not??? Thoughts
would substituting the brass for aluminium give the same results?
Yes, in the real world you would not notice the electrical difference between brass and aluminium
@@andrewmcneil thanks
Very nice! Legal limits aside, is there a theoretical limit to the gain? For instance, if you could build one 10 metres long with the proper parasitic spacing, would it perform that much better?
The easiest way to think about it is an antenna is not an amplifier it’s a radiator. It can only work with the energy available. If you had an iPod and connected two speakers to it you would hear the music fine but if you want to add more speakers say 10 the volume would go down to a whisper as the same energy is shared between the speakers. To lift the leaves you would need to add an amp to lift the power levels it’s the same with RF.
@@andrewmcneil thanks, Andrew. That makes perfect sense. I suppose that the antenna could be as big as you want legally as long as it's rx only, but then of course the limit is the tx of the other access point.
Andrew would it make a difference to the antenna performance if i used 1mm thick copper sheet for all the elements.
In theory it would but I don’t think you would notice. I made a panel antenna in a previous video out of tin and one out of 0.5mm brass. Testing showed a 1db difference.
Hey, which antenna is good enough to kill bluetooth/wifi signal with jammer within 50m range? There might be obstacles like stone fences. These dirty neighbors are PITA.
Epic video! What's the range of the antenna? If using it as a receiver, how far can it go away from source signal?
Hi Andrew, I have always found your videos most interesting being an amateur radio operator and would really appreciate a reply to my previous query. I already have a large sheet of 1mm copper and the thickness difference is the question.
For the driven element and the parasitic elements no but for the reflector yes and its front to back ratio would be different.
Does it help if you have bigger hole and more insulation. Between your ground plane and your driven element.
Is the thickness of metal used critical? You say 2mm for the reflector, would there be any rf negatives to using say 0.5mm?
WHOA Nice
I don't mind learning about these! Wow.
Ready for the next 007 movie.
😁
Just another question if you don’t mind Andrew. How do you calculate the size of the feed point stub, where the coax connects.
That’s the hard bit I have some examples that I tend to use that I have picked up over the years but to work them out from scratch takes calculus. And outside of books I don’t think anybody has ever gone into it in any detail. Not on youtube anyway.
I'm from Indonesia... I'm very inspired by your channel. thank you very much
Awesome! Thank you!
Hi dear master, can you tell me, if I paint the antenna it can interfere with its performance?
What type shed iron you using while made a home booster by yourself?🤔
Would six barrel Wifi gun work better?
Can we buy simmalar thing for this. I dont have tools for making these?
Good job sir ...keep it ...
Will do thanks
Does this work at 5 GHz, with 4 antrennas that do beamforming?
muy bueno sus videos, me gustaria que tambien lo hiciera en español o por lo menos subtitulados a español, ya que hay pocos videos sobre antenas wifi verdaderamente serios y realistas a nivel practico, y una pregunta que le tengo es ¿ como hacer un adaptador de 50ohm para una antena con cable de 75ohm, y tambien como se alimenta la antena del video?
pues te digo mi amigo que la antena no se alimenta en si no usa eléctricidad el cable que ves es para llevar las señales o wifi para tu celu o compu o lo que sea que uses y para poner el adaptador no tengo mucha idea de eso pero estaria bueno para ponerselo al router si es un puerto wifi lo que estas hablando(perdon el testamento de la biblia)
I would like to make 1
How do I get the pdf
hello sir, can this antenna work for 4g signal booster?
This antenna works best for 2.4 GHZ, which is Wi-Fi.
Indonesia has 4G on either 850 MHz or 2.3 GHZ; so you will need to change the dimensions a little.
I'd use a coax panel connector instead of soldering it. I'm lazy. Your method would result in impedance mismatches. 😆
No but coax will work
@@andrewmcneil What works, works. 🙂
Excuse me, could you help me? I do not speak English and I do not understand your good teachings, the plans that you passed to make the antenna have few directors, how is it done to make the antenna with more directors like the one you made and then did the gain tests.
Is it possible to make an omnidirectional antenna that can reach 6 to 10 miles? I ask because I live in the woods with very tall pine trees so I put a directional antenna above the trees. But I have 3 towers near me about 6 miles to ten miles away and was thinking an omnidirectional antenna can pick them up if it's strong enough. If it's possible and you can make one how much would you charge me? I need it for 4g lte fixed wireless
Not @2.4GHz no
hey andrew i wanna question u something what material u use for do the wifi gun?
I used brass for this build
@@andrewmcneil well i want to do one i habe the money and what other materials i can use?
@@andrewmcneil and how much pars max i can put for more range why i want more range why i want go to the forest and do a home there and still habe wifi
hello. i want to build an antenna, but i'm not sure what i'm best off building. i want to be able to connect to my mates network, he's about 300 yards down a straight road, from me. could you point me in the direction of which one of your vids i want to watch and dl the plans from? tia. btw this vid only just showed up about an hour ago, its 2345 on the 5 july and you put it up 2 days ago!
Try building a biquad first
@@andrewmcneil thanks. i'll check your vids and do that.
What are the better builds you mentioned?
Just about any directional antenna
is this will work for gsm?
No its 2.4GHz
@@andrewmcneil pls make gsm gun for gsm :c
Hello can I ask? What is the thickness of the brass plate?
0.5
How many km it can receive wifi signal
Hi sir good job on wifi gun, if i may what about gris dish to bé precise thé tplink tp-link tl-ant2424b antenna, is it good or rubbish !? And thnx
I have never had one but people say they are good for long range wifi.
@@andrewmcneil thank you so much sir, ND good work 😍
i want to buy this antenna.
what is the thickness of the other plate metal? is it 0.5mm?
1mm
@@andrewmcneil thank you very much for letting me know.
Cantenna ebay?

Magnífico 👍
try make triple boom sir 😁
dapatkah kita membuat antena dua polarisai ,vertikal dan horisontal?
This does work in the vertical and horizontal
J'aime beaucoup toutes tes vidéos mais je n'attends pas l'Anglais ☹️
Is this wifi gun connected to amplifier? Most wifi cards have around gain 2-4 dbi but connecting to antenna its worst, because i've figured out that homemade antenna and connecting to wifi card is worst idea due to receiving signal, i made at home one yagi circular antenna and it didn't worked, i've followed any steps in video but nothing also this isolating this driven element. So if this thing can work then how is this amplified? Do i need a very powerful amplifier ? Or can be used wifi card and making giant antenna?
can i buy this antenna?
You can ask me to make you one.
