from the telex faq:

Can I use 2 radios with one antenna?
A: The simple answer is NO. If you plan to use amplifiers, then there is 
absolutely no way to do this without causing major problems and greatly 
reducing the throughput. The amplifier switches from receive to transmit 
upon detection of the transmit carrier from one radio.  The two radios 
would have to be synchronized, both transmitting and receiving at the 
same time.  Without an amplifier, it might be possible if DSSS channels 
1 & 11 were used along with a high-isolation splitter, a low VSWR 
antenna and low ( less than 30 mW) transmit power levels.
