[QUOTE="Terryl, post: 936923, member: 369937"] Also it depends on the type of service your looking at, some things like a satellite system you need a higher frequency response then for a TV signal, for Tv it does not matter too much if the drop off frequency is around 1 GHz, for a satellite system it does, for that type of install a coax rated out to 2.5 or 3 GHz should be used, use the stuff rated for TV signals only in a satellite system and you will have problems. It should be marked on the coax as to its frequency usage, if marked for CATV then don't use it for a satellite system, you can use a coax rated for a satellite system in a TV install, it will work even better. And if the run of coax for a TV system is real long (75 to 100 meters or more) and you use an in-line pre-amp at the antenna, then use coax that has a pure copper center conductor, it has less DC voltage drop (less DC resistance) then the cheap stuff that has a copper plated steel core.
