When using a dual coax relay is it better to terminate the unused port into a short or into a 50 ohm load?? I am using a dual 4 port coax relay to feed 2 radios into a common amp, so should I terminate into short to gnd or a 50 ohm load? 1 radio goes to the amp es other is shorted to gnd es the other way round when relays are keyed!! 73 es Dxis vk3pa
