Re: Hookig up dish
Cathy, Bill is right. You only need to use one. It doesn't matter which one.
My DirecTV receiver has dual inputs. I can watch two different channels at the same time or record one while watching the other. I have to run both wires from the dish.
Another scenario is that you can banish the spouse to the dog house and have another receiver and TV in there! (If you run two wires from the dish into the RV, that is.) :clown:
