Double Biquad Antenna for the 2 4GHz Band

Fully detailed construction of a 16dB gain Double Biquad Antenna for the 2.4GHz wifi band. The biquad is a very simple design but care must be taken when measuring each wavelength. Made correctly it is extremely powerful. There are lots of blogs and videos on the internet showing how to build these, but very few show you how to build it with an enclosure to protect the element.
