I'd be interested to see a picture / diagram of your switch I once foolishly tried a 10kV rated reed relay thinking 10kV rated contacts would surely do the job  - it lasted probably a couple of cycle

Hello Ian, You have me worried now, as does Andy with his last post, the thought of putting a kilowatt into the RX antenna socket of my 590 is not a pleasant or cheap one... Hmmm. -- Best regards, Ch

Chiming in, Fail Safe? Then you are going to want to interlock the Amplifier to avoid a state failure. The Relay has to be part of the loop, interlock so should its position fail you dont assume the

Digressing slightly, but a parallel warning... I once hot disconnected  a BNC plug carrying 700 Watts of RF (Low Z, transmitter output) .    As the contact broke it generated  a plasma arc that shot
