Good point, but I was thinking of a coaxial relay for better isolation 
between the tx and rx ports and protection for the receiver, and shielding to 
minimize RF in the shack spraying around.  But there are always options, and now 
that I think further about it, (A) I could put the relay inside the transmitter 
cabinet, and (B) if I can find a 24 vdc contactor with DPDT action I could 
short the receiver side when the relay is in the tx position for increased 
protection for the receiver.
