If your TRX has a receive antenna loop out the back panel, you can 
readily tap that with something like a splitter (for 3 dB loss) or a 
Clifton Laboratories buffer amplifier.  The buffer amp has quite high 
input impedance, thereby avoiding loading/desensitizing the transceiver 
it is connected to.
