We just built a switch box using two Matsushita RF Reed Relays
(available from AG6K, http://www.somis.org/). One relay goes
to each radio and either grounds its antenna connection or
connects it to the antenna. It is built in a small cast aluminum
box. I use it to switch my transmitting antenna between two
radios. A second switch box of similar design adds a separate
RX antenna connection to the radio.
The isolation is good enough that I can transmit on one
rig and listen on the other ON THE SAME BAND as long as the radios
are >20 kHz apart.
