Biquad Yagi 2 4GHz Wifi Antenna

The Biquad Yagi has turned out to be an excellent directional antenna. Performing much better than I first thought it would. I did change the measurements from the link here: http://homemakeant.blogspot.co.uk/2008/06/biquad-yagi-24ghz-antenna.html

Although this only has 6 elements, 4 parasitic, 1 driven and 1 reflector it out performs a 15 element Yagi from eBay.

Making this antenna is all about preparation, making the measuring blocks as shown in the video. The video is a little longer than normal but I have included every step needed to build the Biquad Yagi.
A big thanks to Preslav Enchev for sending me the link.

    good video matey :-) Would solid 1.5mm or 2.5mm copper wire work given same measurements for elements?

    Hi Andrew. Thanks for this. One question. you mention that 31.5mm is in the middle of the 2.4Ghz bandwidth, but that comes out to 2.380Ghz, while Channel 6 is 2.437Ghz. Is there a specific reason why you chose 31.5 as a quarter-wavelength?

    TIA...Eric
