Interesting.. I dont have a power supply plate on this RV, but did on my 85 Pace, and it was not built like that. There are a few coupling caps and a choke or two.
There is no reason to break coax to the antenna, and especially since at UHF the coupling across that little slide switch is significant.
If it really is built that way and it was mine it would be fixed by the end of the day.
There really is nothing to "fix." The switch chooses input from either the outside cable connection or the antenna. The 12V power is applied to only the antenna for its built-in amplifier. If the two inputs were coupled, then 12V power would be supplied to the campground system.
The dimwits that built my trailer installed the switch where it could not be seen or reached. I thought that I could add a power switch installed where it could be used. When I pulled the plate I learned that it can't be done for the reasons mentioned above.
You didn't mention it's also an Ant-Ext switch. Obviously not the normal power inserter.
