Currently I have 2 lines coming in the house from a stationary dish. There is a 4x1 disec switch attached to both (so 4 Dual LNB's). I would like to add a motorized dish and leave the existing LNB's where they are (for other TV's in the house). So hopefully, one TV with a Viewsat will be able to get fed from both dishes, and leave the others. How do I feed the new motorized dish into my existing full 4x1 switch?
