I just discovered coaxial relays and I was wondering if there was any way to use some sort of current sensing relay to trigger the coaxial relays as to disconnect other radios antennas when I key up a radio. For example, if I have 2 scanners, a ham radio and a CB radio and the antennas are mounted near each other on the trunk, I want to disconnect the scanner antenna and CB when I key up the ham, or disconnect the ham and scanner when I key up the CB.
Also, did someone already do this and am I just reinventing the wheel?
