Default Using existing 72 ohm RV cabling

The coax is routed through the RV but not connected to the TV antenna system. In my case, I don't hook up to cable at the parks, and what TV I watch is Over the air.

Just a thought.
Bud, the coax for cable tv operation usually is routed via the TV pre-amplifier for the roof TV antenna. If the Amplifier is switched off, the cable tv routes through the amplifier. If the Amplifier is ON, the tv signal from the antenna is amplified. I would not use the cable tv coax for any ham rf use, unless you want to see and smell smoke.
