Phottix Pro Photo Accessories. Biquad Antenna Construction. (first published September 2002) This page details the construction of a biquad antenna.

The Biquad Yagi is a powerful hybrid antenna that I have developed over the past 3 years. It all started when I was sent a picture of an unusual antenna found on the internet by one of my YouTube subscribers. It peaked my interest as it was indeed unusual, a strange cross between a Yagi wrapped around a Biquad style element shape. Reset epson l382 adjustment program download. So I built one and to cut a long story short, it did not work! I did like the idea though so I changed the design, tweaked the measurements and simplified the construction and what do you know boom it worked. Infect it did more than work for its size it was more powerful than a 14 element Yagi.

So I made a video to share the measurements as well as showing how to make one for yourself. So a year went by and in that year I had been inundated with emails from people asking if I would sell them but the problem was the original design was not very sturdy it needed constant maintenance as the solder joints would fail and the overall construction was not production friendly as it took around 12 hours to make just one. So I went back to the drawing board and 3 years on I have sold over 500 of the stranded 2.4GHz version alone. So why offer a Kickstarter I here you ask? Well for the past 18 months I have sold the standard 2.4GHz Biquad Yagi using the money to develop the long range version and the 5,8GHz version for FPV. And in that time the price has stayed the same even though production costs have increased.

So to launch the long range and FPV versions I have decided to offer all three as a Kickstarter and this way if successful a higher volume order will enable me to offer them at the same price they were 18 months ago.

This 15 element DIY USB Wifi Yagi antenna works better then my Cantenna. Now that it operates perfectly I feel confident enough to build a bigger Yagi antenna. According to the web host from the web page where I found the instructions on how to build this antenna it has no use to build an antenna with more then 22 elements because it would not give a lot more gain.

But 22 elements is fine and that would give about 22dB gain, so it is worth the effort to make a 22 element Yagi antenna. All I have to do is to make new elements from standard 14 Gauge copper wire (in metric 1,62mm or 2,5 kwadraat) and make a new boom with 22 holes.

I will recycle the hacked USB stick because I can only use 1 antenna at a time. All the credits go to the web host from the web page shown down below, Mr. Phillip Collier. Special thanks to you for sharing the information.
