Our new home if Fla is wired (R6) for cable via an OnQ box which contains a basic 1 X 4 splitter to 4 locations.

I want to add a a DTV satellite receiver at one TV location. I'm told I can use an outside Sat/CTV diplexer to bring in a combined signal to the OnQ box.

My question: What is the best way to send the CTV signal to 3 locations while sending a combined (Sat/CTV) signal to 1 location.

Appreciate any advice here!
