There's an easy way to overcome this. Like "Bob123" said, satellite receives don't like splitters. Pull the antenna amplifier plate off and find the direct line in from the outside and disconnect it. Take one of those wall plates that has two coax connectors on it. Hook the outside line to one side on the back and label that line "Sat" and the other line on the back goes back to the antenna amplifier. Label it "Ant." When you're using the satellite, hook the input for the receiver directly to the line you just marked "Sat" and the output of the receiver to "Ant." Your satellite dish will be hooked up to the outside connection. When you're using the regular antenna or hooked up to cable TV, just put a short coax jumper from "Sat" to "Ant." The ONLY time you should need the amp on is for the antenna. I mounted this plate right above the antenna amp plate.
