Good day EXGMtech,I just hooked mine up to cable for the first time tonight and the picture is very good in the bunkhouse,living room(even on the Legend
),and the master but make sure the amplifier is off.I don't know if there is a splitter or not because on my old 5er the Winegard amplifier had a output port for the bedroom on the backside of the wall plate,not sure the new ones will have the same setup or not but just pull the amplifier/wall plate and see and just fyi the black wire is cable/antenna and the orange is for the satellite.I hope this will help you out and let us know if you find something
