No matter the quality of the cables, connectors and splitters, the wall plates you see labeled TV/Cable are not for use with satellite. You have one coax coming into your coach and going directly to the wall plate labeled satellite. This is the only place in the RV where a satellite receiver can be located (without major modification). You will only be able to use a receiver at this location. From this receiver you can feed the satellite signal to other TV's in the coach but you will not be able to place other receivers elsewhere.
