Hi Les,

I have an FCD (not Pro) that I use pretty often for satellites and a TS2000
for the main rig  Given that the T and R bands are always different, and
given that the TS2000 has separate inputs for U and V bands, I use a coax
switch on each antenna (type N for UHF).  One output of each coax switch
goes to the matching antenna of the TS2000.  The other goes to a U/V
diplexer (again with N-type connectors).  Then this goes into the FCD.

Of course there is some loss, but I have RF-switched preamps out on the
antennas so that is less critical.
