The Waveguide Panel Antenna

In this video I will show you how to build your own small but powerful 14dBi waveguide (cantenna) with a panel antenna replacing the more common monopole. The waveguide is constructed out of 1.5mm thick aluminium giving it an impressive front to back ratio. As such more of the RF power is focused forward in a 45 degree beamwidth.

Happy new year everyone. First video of 2024 is a build video, these tend to be longer but hopefully I have included all the info you need to build one for yourself. I have also put a few on eBay if you wish to buy one.
Hi andrew, I live in a rural area and my nearest tower has downlink frequencies of 734 MHz, but most of your videos are about 2.4 Ghz antennas. Can you help me please?
That is some excellent fabrication andrew. Its good to see you back making videos.
Nice make! Thanks for sharing. 👍👍👍
that's amazing; but what would take to make a 20+ db version of this? have you ever tried to put your 2 foot long brass gun in a can? do you think all the measurements would have to change?!
Is there a way to make a receiver that can pick up 3G or 4G networks from outside the house and then broadcast them back inside the house
مرحبا سيد andrew كيف يمكنني ان ارسل لك صور نموذج بسيط جدآ تعلمته من يوتيوب لكن به بعض المشاكل اشك ان المشكلة بالقياسات
احتاج ان تلقي عليه نظرة وتفيدنا بتوجيهاتك
هذا النموذج الوحيد الذي اعطى استجابة لدي لأني اعاني من ضعف النت في منطقتي
ارجو ان تفيدني ولك الشكر
Hello Mr. Andrew, how can I send you pictures of a very simple model that I learned from UA-cam, but it has some problems? I suspect that the problem is with the measurements.
I need you to take a look at it and provide us with your guidance
This is the only model that gave me a response because I suffer from weak internet in my area
I hope you can help me, thank you

Anyone happens to know of an online calculator or equations to use with a different sized container?

Can you make 5g Antenna in simple way
There is a thing called aluminium loaded epoxy resin. That will give you electricity conductive bond. Also you can buy silver loaded epoxy resin but it is very expensive but again it will give good mechanical bond as well as a good electric bond.

How do you measure the gain of the antennas you design?
There are anyzers which measure the reflection of power of different frequencies of the antenna.
Tools can cost you a leg and an arm, a house, or you can get small cheap ones like the NanoVNA (well, maybe also not super cheap, but much cheaper than theothers, around 100-200$)
@@tarakivu8861 yes that is how the reflection power is measured. But I'm asking how is the gain measured?
Hello Sir ❤
I have been following your account since 5 months , one thing I have come to realise that you have extreme knowledge but your subscribers are way less than you deserve.
You deserve a million subscribers of what you are doing.
I would recommend you using attractive thumbnails for your videos , which will make your videos attractive and another thing you could do is make your voice a bit clear in the videos.
I hope you see this comment.
Lots of love ❤
Great video as always. Is each square on the network analyzer 1db? and could you show us how to make a high gain antenna for 1090mhz? I bought one on Aliexpress which was supposedly 12dbi but it performed terribly.
good video Andrew ! I really enjoy watching your videos, they are full of details and very well made ! i am curious what would your opinion be regarding an compact antenna for GOES satellites would be great if you would tackle this subject :D
Many thanks for your time spent on this educational videos !
Hi Andrew
Nice video. Thanks!
I want to build it. But my tube ha an inner diameter of 78mm.
How can I calculate the lenght and the position of the wave catcher?
Looks nice and great results with the network analyser! 👍👍
Quality job Andrew
One question?
Is that central bolt isolated from the main driven element?
I guess it must be 🤔
I have the same question. It doesn't look to be isolated.
I was thinking that using some of the aluminum "brazing" material to at least "tack" the aluminum reflector to the tubing would give a guaranteed electrical bond, if that is critical, because the aluminum oxidizes quite quickly to a nonconductive surface... Just a thought?
I'm from Indonesia, I always make your videos for study reference. Thank you very much Andrew
ممكن تكتب ياندرو لوسمحت من فضلك كم قياسات الاقراص وانا مدمن على فيديوهاتك شكرا 👃
if i build a biquad antenna should i connect the driven to the coax ground? since i saw that you du such things on all of your biquad antenna, i never build biquad before but im used to building yagi with a dipole driven element and they usually tell us to use 4:1 coax balun and not just connect the other side to the coax shield which gonna makes rf travels on the outer shield and probably interfeering with the inner coax core where the rf should be
i would Love to see a FAXE Beer can Antenna, it has a metal body, so you can solder on it.
Excuse me sir, can I ask why the elements in a 2.4ghz antenna are 25mm lenth if the wave lenth is 125mm?
capacitance
@@andrewmcneil Thank you.
Eso es debido a que se calculan a 1/4 de longitud de onda de la frecuencia y a su vez teniendo en cuenta el factor de velocidad de la luz en los materiales que es diferente a la del vacío. Por esta razón es que salen más cortas las medidas de la antena física.
Isn't the driven element shorted to the enclosure using the screw? I thought it shouldn't be
Yes if we wanted it isolated the measurements would be different and would not work as well. Shorting in RF does not have the same outcome as shorting electrically

Can you put the link to the pipe you bought on ebay?! Thanks!

Disregard my last comment. I found your store. There is a dead hyper link in your channel description.
Great build!! I went the eBay link in your channel description and I couldn’t find your store. If there’s a different link please let me know. Thanks for the video!
You might try to expand the brass wire or tube to "rivet" it onto your driven element.. just 'because,' I reckon.. 😀
Hello Andres. A pleasure to write to you.
I'm wondering if it's possible to replace the M6 screw with an M2 or M3 one. In my experience, using a thinner screw has given me better results, and even better using a plastic screw. I don't know if it is possible to try those variants.
Thank you

Hola Andrew. Un placer escribirle.
Me pregunto si es posible remplazar el tornillo M6 por uno M2 o M3. En mi experiencia me ha dado mayor resultado usar un tornillos mas delgado, incluso mejor utilizando un tornillo plástico. No se si es posible probar esas variantes.
Saludos
Fantastic video
Fantastic job !
