Why do you need 4 frequencies? Are you dispatching or coordinating 4 discrete areas/zones?
The alternative is to have 4 inputs to one output which sounds like a huge amount of work and trouble for no gain.
Just program all of your base units to use the same transmit (repeater input) frequency and tone. Your bases would then act just like your mobiles.
(make sure to license each of those bases as station class FX1 if they do use the repeater)
