I too am wondering about hooking an OTA to my system. I have a CM4228, a Dish 1000.2, a 622 and a 222, with 4 tv's. The dish 1000.2 has just 2 wires comeing into the house. What I would like is to put the CM4228 up nest to the Dish, and wire it in so all 4 Tv's would have access to the OTA's. Where can I get a diagram, to wire this in, with combiners/ splitters? Any and all good advice will be greatly appreciated.
