That's a really interesting problem! I'm not sure if it's related to what I discovered but here it is...
As David correctly pointed out, the 2 cables in the back of the King jack plate inside run to the outside sat/cable hookup and the powered antenna hookup respectively... What I've discovered is that, if I plug my Klein Coax Explorer directly into the coax behind the port, it detects the circuit, but if I plug it into the TV1 Jack on the outside of King jack plate (where your normal TV plugs into) with the amplifier turned OFF or ON, it does not detect a circuit to the outside cable connection, which leads me to believe the King circuit board interferes somehow with my little Coax Explorer tool. I don't have a cable TV connection nearby to test out to see if TV channels actually get through, but that would be interesting to see.
My hidden motivation was actually to connect a cable modem / Wi-Fi router inside of the Escape to hook it up to an internet connection at it's current location through said outside cable/sat jack, but I think I'm going to just leave it in a weatherpoof plastic enclosure and not bother with the jumble of cables and whatever untold effects from the radiation I'd be picking up sleeping 2 feet away from a Wi-Fi router. : )
Thank y'all both for your help.
