Gonzo, I also have one in my electrical storage area. But only one and it's for cable only. Tried hooking the satellite dish to it and no reception. My TV has a mode for air or cable. You would think that connector in the electrical box would work with satellite if it worked for cable. I haven't tried hooking up the dish in a few years or with my new receiver. After the dish is attached to the electrical box connector, I removed the coax jumper at the TV coming from the TV cabinet back wall. I then attached it to the receiver's input and added a jumper for the output to the TV. The TV was set to cable. No reception.
But I will try setting it up again this weekend and see if it works.
