All,
I agree with Bill and KD9SV is nothing more that what BIll is talking
about.
Just put the relays into the box and connect between radio and
preamp/ant done.

I suppose some people who use full break-in want a complicated
solid-state front-end protector. I don't use break-in and so a simple
DPDT relay powered from your transceiver will do the job at almost $0.
One side grounds the auxilliary RX antenna port on the transceiver while
the other grounds the RX antenna feedline. Foolproof, and you always
know if it is working since you can hear the relay kick in every time you
transmit.
I have been using one of these for many yearsever since my linear
developed a mind of its own when RF started feeding back into the
transceiver's auxilliary RX port. I've never had a problem and it
protects the front end 100%. 'Course I'm a dinosaur 'cuz I don't use
full break-in.but I suspect there are many like me!!
