Hi Barry
I just built some antenna switches to switch antennas between radios. I
have one 2-position switch for each antenna. Each switch goes to a 7
position switch at each radio. That way I can select whichever antenna I
want to go to either radio. No danger of transmitting into front end of a
radio that way. 73
