I was on a cruise ship out on the open seas once and at the big dinner the nice folks sitting at table with us were complaining they couldn't understand why they couldn't get get cable tv in their room.
Sooo... you're at an RV camp that provides cable tv?

Normally the King antenna is energized when you wish to receive OTA TV signals and is deenergized when using cable TV
The King Antenna manual on the internet says roughly the same thing and my experience is similar
Thanks for all the suggestions . Turned out to be one of the cable connectors on the back of the King switch did not get crimped. It probably test ok at ETI but the bouncing highways allowed the wire to pull right out.
