Layout is as important as the power handling. I doubt if any open frame
relay would have perfect VSWR above 15-20M and that would affect filter
performance. The relays could be compensated with capacitors.
Rather than go thru the hassles I used filters betwen xcvrs and amps and
then hi Q coax stubs on feedlines since everything here is monobanders.
It completely eliminated interference between radios in a contest enviroment
with less than ideal TS-940 phase noise performance.
