Tony, Most of the time I work in diversity on 160 and 80 when in contest. I tested the antenna setup by transmitting in one antenne and measure the power delivered by the other antenna to a 50ohm resistor. As long as the power (worst case situation) is low enough (I use a 10mW limit) there's no problem.
(BTW, for the people who want to know, my powermeter can measure from -50dBm to +30dBm) I'd like to add a question: what do other people use as a limit? 73 Arie PA3A Op 7-1-2011 1:27, Tony Estep schreef: > Nobody commented on my question last night, but I'd still like to hear from > your collective wisdom, so here's a repeat: I set up my sub-rx to listen on > transmit antenna B while the main is listening and transmitting on A, and to > listen on A while main is listening and transmitting on B.
