I have a dumb question. I am running a line from my dish network dish to the receiver. I know that it has to be RG6, but I read on another forum that if the cable has "RG6" and "CATV" on it that it will not work. Is this true? I have two spools, one is RG6 and has "CATVP" (plenum) and the other is RG6 with "CATV" on it. The run is about 100-150 ft.
