Installed a satellite on our 31 FS to feed the front and bedroom TV's. Mounted center toward the front, drilled through the roof and fed the wiring into the over dinette cabinetry. Straight shot to the TV area and splitter to the bedroom TV. Your model may be different, but hope this helps. Works great, and with a proper roof sealing no leaks!
