I'm wiring my dads new home, and I'm to the point of running some RG-6QS from where the dish will be mounted to where the reciever will be. Will a single run of RG-6QS to the wall plate where the 722 will be be acceptable? From what I can gather online, a single run to the wallplate is ok. Is there one input fot the 722 sat in or two? Can a splitter be used if there's two. I really don't want to run two coax lines from the dish to the living room.This is my first experience with anything other than a simple Dish500 system install. Any help is appreciated. FYI, I'll be using a dish 1000.4 (eastern arc) here.
