On my motorhome, I have one input from a satellite dome on the roof, one from an antenna that I can put on the ground, and one from a cable tv source. My last coach had one A/B switch that I could use that would switch between these sources. Basically I want to choose between the roof antenna and one of the others with one switch (I hope that this is clear). I know that the switch has to be high isolation.
