A lot easier to make then the biquad yagi. Another awesome video, thank you Andrew. I eagerly await your longer Biquad Yagi kit.

Hi Andrew, for this design (1 λ driven element) you are actually building a quagi. The only difference that I see is that your back reflector is not a closed loop. Congrats for your videos you are doing a public service in public education!

a thought use a straight edge to line up the parasitic elements .. I very much like the details in the builds you add.using the benchtop to make sure the parts all line up, priceless

Thx bro!!! I bought a bunch of high powered transmitters and antennas, but couldn`t get a good range. Then I build one of these. And even if my lady and friends were laughing about me, I gave it a try. I endet up at around 1.6km. But the best to come: I forgot to power up the transmitter via smart audio, so the range was claimed at 25mW!!!

Awesome video Andrew, could you make a 24gb and 60gb yagi, these are the other legal frequency and are often used by ubiquiti ants. These would make very Interesting and entertaining videos

andrew , I watched some videos on youtube channel where used helical antenna pointing for metallic plate, like the principle of satellite dishes , so better dissipates the signal ? If I put a mini yagi antenna reflecting work? I use the 5.8 boscam the 5885 channel , what do you think ?

I Andrew and thank you for all these videos. I have a question for you; is there any concern using a 4 mm in diameter instead of 3? And what about to use iron instead of aluminum?
@andrewmcneil

you could use 4mm but iron is a poor conductor when compared to copper and aluminium

May I ask you if you think this type of antenna would be good for a transmitter? I'm seriously feed up with all the antennas that are sold that supposedly give your more range ... but it finish been a truck load of horse manure I did use. Custom, Tuned, Circular Polarized antennas "Really expensive ones.. until a day that I didn't have other choose but to test with a regular antenna to find out that the regular was at least 20 times more powerful than the ones that I was paying an arm and a leg.... Would you please consider to advice on a directional transmitting antenna? please??

yeah, unless you're flying in a straight line, a directional antenna has to be pointing at whatever it's transmitting/recievng from. you can probaly use a auto tracker, but that would add a lot of weight, and as long as you're using a omni on one and a yagi on the other, it's the same vice versa

The helical is a circular polarized antanna - wich is good to get rid of multipathing because it rejects inverted signals but it's range is not as high as the range of a linear polarized antenna like a yagi.

Yep, centre of coax to one side of the loop, and shield to the other. It makes a close to 50 ohm feed, give or take.

Short answer no and the equipment to detect and analyse waves past 50 GHz would cost the same as an average house
