proper mount to your feedhorn
Schematic of a cirquit which I presented at the EME conference 2000 in Rio de Janeiro. The system has been realized in my EME station since 1997 and allows permanent control of the whole rf-path up to the dish and down to the converter. Nesting birds in the feedhorn, water in the cables, connector faults etc. can be detected while transmitting. Furthermore, the rf power in the feedhorn, isolation and return loss are under permanent control. I strongly recommend to go for it.
