Here I am working on a circularly polarized 440 MHz antenna for satellite
ops. The first screenshot shows initial results when it was first
connected. The second trace is after tuning. To be able to see Return Loss
and the Smith Chart at the same time, in real time, was invaluable in
getting this thing corralled.
Next step: build a second one and phase them to give me a 2 bay CP
transmit antenna with 0 dBi gain. Exactly what I wanted.
