Coax connections on surge protectors OK for sat or cable?

    The surge protection devices in my price range seem to have 3 coax connections. One of the devices labelled them as 1 satellite and 2 cable. Is there really a difference in the protection required for a satellite input versus a cable input? I have a Philips TIVO satellite receiver which uses two satellite inputs.

    Thanks. Bill

    bill, according to some recent research I found, I conclude that sat and tv coax ports are not interchangeable:

    Satellite coax feeds 13v and 18v signals from the dish LNBs. A SAT designed coax surge suppressor port carries about 27v clamping.

    Cable tv ports will carry ~ 0.7v clamping.

    If one connects the SAT coax into the Cable tv port, that port MAY block the SAT signals.
