WI-Radar Project
posted June 11 2010 19:34.42




AiFiLTr0 was frustrated by the wimax signal quality, so he went off making a good wimax antenna. He ended up using a biquad antenna, tuned for WiMax, This was easy but who was going to position it? The servo from a flatbed scanner gave the solution and now the wi-radar is born. The sources and PCB layouts will be posted here soon so stay tuned.
