My '13 FB has a satellite splitter in the ceiling light to the right above the bedroom tv that splits to the garage connection.
I didn't check it as I don't use satellite, but there's also a splitter for antenna/cable there also that was hooked up incorrectly, they had the incoming cable on one of the outgoing spots which gave us a great signal in the bedroom & nearly none in the living room.
IIRC the antenna/cable went to the booster from there to the splitter in the ceiling & from there to the bedroom, living room & garage connections.
