I am hooking the connection to the portable input in the wet bay. I then hook the receiver to the portable input in the overhead. The receiver connects to main tv via hdmi cable. This works well. Somewhere in the background there are other connections I assume that link the TV's to the switch in the other front compartment. The switch has 3 TV options and sat, antenna, cable DVD . I am able to get antenna to bedroom as well as rooftop sat to bedroom receiver. I understand my outside tv will have the same as the main tv. Wonder if I can get same as main in bedroom.
