This should work, but you'll lose flexibility: each tuner will be able 
to use only the signals from its own antenna.  If you have highly 
directional antennas and transmitters in different directions, combining 
and then splitting would allow more flexible scheduling.  You'll be 
likely to have problems in combining, though, if one transmitter can be 
received with comparable signal strength by more than one antenna.
