Quadrafilar Helix antenna for 436 Mhz
This is an antenna that I just built. I intend on using for receiving the AO-27 downlink at 436.800 +/- doppler. It is built with right hand circular polarization, and the gain is supposed to be in the neighborhood of 3 DB
Quadrifilar helix antenna for 137 Mhz
I had always wanted to try and receive a signal from a satellite using my scanner
