[QUOTE="Jason Lavoie, post: 25961, member: 159"] Re: Switching RF outputs the reason is that RF video (really VHF and UHV transmissions confined to a cable) are higher frequency than baseband video, so any video switch won't be setup to pass those frequencies. I don't know if I've heard of an RF video switcher/router, and I wouldn't expect to see one because RF contains multiple channels so the switcing is done at the TV set. the only solution I can think of is to get a good distribution amp with multiple isolated outputs, then add on an RS232 controlled relay pack to simply disconnect each feed. the DA will also help make up for any loss through the non-RF relays check these guys out for simple relay packs.
