I have a panamax 1500 surge protector. It's got 3 spots on the back for signal inputs: * Satellite in/out * Antenna in/out * Additional TV in/out They all 'look' they same. I had been using the satellite in/out for protecting the direct tv feed to the dss receiver. Then i recently upgraded to a Tivo and now am pulling 2 satellite feeds into the HT area. Can I just use the Antenna or Additional TV jacks for protecting the 2nd satellite feed? Would that work? Internally are they the same? Thanks a lot.
