I use a Dow Key 412-2301 Transfer Relay to select my 6m kilowatt amp 
or bypass it to the antenna.  It is powered with 26vdc and has 
N-connectors.  Don't recall isolation figures but think they were in 
60-dB range.  One could use this relay for TR with a kW amp, or to 
connect to two radios to two antennas or loads.  Its wired like a 
DPDT with internal crossover.  It cost me $40 used.

BTW if you have some of these surplus 24-28vdc relays, I sell a 
regulated 5A power supply that is adjustable to 28v:
