How much isolation should I be aiming for in a remote relay switch box. I have some 30A rated relays that look as if they will handle a fair amount of power. I can see only about 40dB of isolation across the open contact. I don't need it to go above 30MHz and 2kW handling should be fine. Antenna connections will be all low impedance. So 1kw into the common port will give me about 10mW at the open port, enough?
