Most splitters, couplers, or combiners in the communications field are
designed to be unidirectional not bidirectional.  Unidirectional couplers or
splitters will attenuate the RF signal typically 20db or more which would
prevent any high power being applied to the other comm.  That really should
be the least of your worries.  Bidirectional couplers on the other hand are
designed to split or couple the RF signal with minimal loss and would be in
a position to route the high power to the other antenna.  I wouldn't worry
at all about high power RF coupling back into ther other comm.
