I think Larry is right.. let us know how it works out..

I do have a question for you though,, I'm a little confused about what is going on..
You have three sources and you modulated the sat signals then combined the signals and then split them to go throughout the house.

So if the sats are modulated the customer has to put the tv to the specified channel lets say channel 87. Once it is on Channel 87 how is the sat channel changed?
