The recent reference to KK1L's switch is interesting. He uses 3 SPDT
relays per "antenna port", which makes it fail safe, at least as far as
not connecting two radios together accidentally.
There's also an HP ap note, AN332, which I don't think is online, which
is a good summary of all sorts of rf switching. I see it's not marked
with a copyright, so maybe I can put it online. I'll write to Agilent
and ask.
