In a conductive space like you have, the wavelength is not the same as free space. You effectively have a capacitively coupled loading on the ends of the elements. A much larger diameter tube would likely do better. The area over which you take the RF energy is about equal to the tube's cross section. The efficiency with which you then bring it into the COAX is the big thing to optimize.
Andrew, this is very similar to antennas we used to use back in the 80s on news gathering vans to shoot a microwave signal back to the studio on around 2300 MHz. And some of us ham operators used to make these to shoot video to each other across town. The difference is that we made waveguides from coffee cans. A small hole drilled in the can 1/4 wave from the back of the can and a 1/4 wave of center conductor of 50 ohm coax protruding into the can made up the driven element. The can was then inserted into a short section of PVC pipe just larger diameter and a PVC cap glued on. This made for a rigid mount of the long all-thread rod which contained 20 or 30 washer discs of the proper size and spaced with plastic spacers. Nuts only at each end of the rod which was about 3 or 4 feet long. Lots of gain and narrow beam width. Sorry, I don't have dimensions to give you but you may not be far off with your project. I suspect that by inserting your parasitic elements down into the waveguide may introduce some unwanted reflection and SWR. I would shorten the waveguide and then mount the parasitic elements out on the end of the waveguide tube.
You will find that when you are attaching the center wire of a coax to your driven element if it's a flat plane such as this, the best match to the coax needs to be experimented with. If you have a spectrum analyzer, connect the coax to the analyzer and aim the antenna at a known signal source and touch the center wire of the coax to various areas of the driven element. You will find that you get a much stronger signal on some areas of the driven element than others due to a better impedance match. Once you have found a place with the best match, solder the center wire to that point. Excellent series of videos and very interesting.
Firstly, thank you so much Mr Andrew for all the exceptional work that you do for us, secondly, I have a question about the diameter of the discs that we must use, on the video you use discs of 34 mm but on the pdf you use 32 mm discs.
Hi, great video, but I have a few questions. 1) Why shouldn't I use washers as the circle elements to build my WiFi gun...is thinner material better? 2) If I were to use washers, how does that affect my spacing? What I mean is, is the spacing measured between the two facing surfaces, or since the washers are significantly thicker, should the spacing be measured center to center? Thanks.
I'm wondering if the reason the original design used a drive element 5mm larger and parasitic elements 3mm larger than your design is because the original plans called for a 4mm threaded rod. Perhaps the original designer intended for the builder to use a non-metallic rod, but he used a metal rod instead. Is it the overall diameter of the circular element that matters or is it the cross sectional length of metal that should be measured? I'm sure I'm not saying it right, but perhaps the original calculations take into account that there's a hole in the middle of the circular elements.
Well done, Mr. Andrew. If it possible, please update the document (in PDF) the exact thin of the element & the diameter of axes, please. Because my English is not good, especially in listening. Thank you very much.
The antenna thing really works. Even the ukrainian youtube team named kreosan did this (70 Decibels was the max). The farthest is 7 to 12 kilometers from their experiment location to the target Wi-Fi. The reception is cut when snowing but can receive the signals.
Hello I just wanted to say that your video is great and the end product looks great. I would like to ask if you think that this general setup would be effective for a 900 MHz antenna and how are you calculating the dimensions of the parasitic and active elements. Also how do you determine the dimensions for the can you wish to use. Thank you advance for any information you can give me on this. I am currently looking at building one and just need to calculate the dimensions that I need.
I have a recommendation for you experimentation. Try with one or two parasitic elements, and separation between reflector form active elements. That can be better about, from my experiences experimentation.
My new favorite diy antenna channel! Very informative with all sorts of designs and REAL TESTS! Thank you so much! Im making the antenna from the “My New Favorite Antenna” video. Quick question. If I want to make the antenna from this video but for 5ghz wifi, what diameter should my circular elements be? Thanks!
The difference between the metal threaded rod and plasctic threaded rod: all dishes are circuit short cut onto the metal one. All dishes are isolated from each other onto the plastic one, so, i think there is a problem with the metal one: you solder the ends of the cable one way onto a short cut (metal), the otrher way you solder the ends onto isolated dishes, like a capacitor. Can you explain the sense of these two extreme difference?
i would like to see the signal strength difference between this antenna and the ordinary built in adapter in my laptop, but no he just gives us a signal strength wuote when the router could be 20 feet away
Ok so I have a question on the dimensions used for the WiFi gun. Aren't the diameter of the directors supposed to be just a fraction under the length of a half wavelength? The frequency of WiFi starts at 2.4Ghz, meaning half it's wavelength should be 58-62mm. The directors in the WiFi gun is 37mm. Any reason why?
@andrew mcneil, can you please help out?, your diagram on the cantenna had the scale 20 X 20. How do I apply this to the precut disc diameter? Many thanks.
wonder if the "waves" are not blocked too much because round elements, just a thought that it might reflect too much before it hits the driven. At the moment testing my 2,4 sector antenna which stated as 16dbi and 90 degrees radiation pattern , so far very interesting result with 40+ wifi points while my phone pickup about 10. Need to find spare time to inspect the inner what should have 8 cone-shapes on some board and seperated H and V connectors.
A few people have said that maybe using less elements may make it perform better I will give it a go when the weather warms up as it does make sense when you think about it.
yup, would be so nice for a long distance test in some open land to avoid all kind of reflections. Agree the weather needs better first lol, here tons of rain in Holland, all coming from UK as wind is from west hehe
Yagi antenna has a wider range and cantina narrow range as you explain in your last video now you have to merge two design together with how is the range?
hey there andrew, i was just wondering if you could mabe send me a link or a list or something where i could buy all the items u use to build your wifi antenna's such as the coaxial cables,heat shrink tubing, double sided copper clad board...etc oh and especially the stainless steel toilet brush holder for the cantenna designs. Thank you again for your content your awsome!
His design has the driven element at 1/2 wavelength and the others at 1/4 wavelength. 2.1 GHz is 143 mm & 1.8 GHz is 167 mm. You’ll also want to change your spacing. If you look up yagi spacing calculator, find one that lets you choose all of your variables, such as number of elements, diameter of parasitic elements, frequency.
Any idea where one can get the toilet brush holder he uses in some of these videos? I looked up walmarts catalogue and couldn't find anything that looks like that one, cheers
In fact, you don't need to find that kind of cylinder. You can find an ideal paper cylinder and stick a layer of tin platinum paper on the outside, which can also play the same role.
i was thinking of making this one but i would like to do it with my Xiaomi Mi Wifi Repeater Pro but its antenna is built to it (unlike from the video that you can disassemble or remove the amtenna). Would it be fine if sattelite/cable tv wire is Twiddled to the repeater antenna directly? can i get signal with that (of course with the same directional antenna design) please i hope and ill be very glad if someone read this and answer my question. (sorry for the wrong grammar)
I would like to build this kind of antenna (with or withough the can) for my local 800MHz LTE connection because it seems a little easier to make than other directional designs. Are sizings available for 800MHz, or is there a good online calculator which could provide that?
Andrew, could you please show how to solder wire to the stainless steel. I was trying a lot in a different ways, but unsuccessful to make a proper soldering. Thank you!
These are not true stainless steel they are a mix with a lot of tin. I have come across some that just will not solder even when buying from the same store. I got 10 of these last year same make same store and two of them would not solder.
pilipoff Anytime soldering a steel or iron part, use flux and it'll be easy. Flux paste or acid flux, plumbers flux or hydrochloric acid - each will do the job, but be careful with the acid.
What job do all the parasitic elements do if they are all seperated from the can? You only seperated the driven element from the reflector in previous antenna?
Your diagram doesn't have a length & width measurement for the can, is it important? Dose it mater if the can is aluminum or another material? What type of tube are you using? Can I use a stack of soup cans for the tube? I like to get my details together, less chance mistakes on my part. I need an electronics for dummies book. :(
I have a question. I was looking to make something of this design for my parents when they are trailer camping during their summers. Is there a way that this can be connected to a wifi router in their trailer so it can be used for multi devices?
Please could you direct me to a video to help with home WiFi. Typically, we have the Virgin router and I want to boost the signal. I've used a bt router as attachment repeater, but it would be great if the signal was much stronger. Thanks in advance. BM
Do you half to use coaxial cable or will any copper wire work ? I'm want to attach it to a WiFi extender antenna if that makes sense if anyone can tell me that would be great thanks
Hello andrew can you give me a link to your store? Tried the other video that you have uploaded and the link seems dead.. If you could pm me a link or just post one here it would be very appreciated.

I have a TP-LINK model TL-WR840N router. I want to send signal to a repeater 2 floors bellow where the router is.

I love the way you go explaining things during the video and in the end there's no doubt left... You're the best!!
Thanks PU4ALZ but some people think I talk to much! LOL
Sometimes "too much" is just what we need. Thanks for that
I think you need a way to match the antenna. Measuring the VSWR would be a good start. 🙂
