External Antenna to Cable Connector

What you are calling the amplifier is most likey not.. It is however a switch (Even if it is the amplifer)

If you are the ORIGINAL owner and you or all previous owners, if you are not,, and still you.. have not re-wired (Which is very very common) then the park cable inlet should run to the back of the WINEGARD wall palte... TURN OFF the wall plate to select cable (turn it on to select the rooftop batwing).

As long as your external antenna doesn't need an amplifier, just hook it to the cable port and leave the power button off at the panel. Make sure you set your TV to scan the OTA channels, not cable channels. With the power switched off at the panel, the cable connection feeds straight through to the TV. We used that setup when parked at our upstate NY cottage before we switched to satellite.

Thanks for the help. I realize now that I have the same situation as folks with satellite and who only have a cable connector.

The problem you are going to run into is the antenna panel in your RV wants to send +12VDC up to your outdoor antenna built-in PREAMPLIFIER. The splitter in the CABLE TV LOOP will prevent this from happening.

If you can get around this problem it should work just fine.

I would setup another BAT WING or maybe one of those JACK Antennas at your house and once you manually point it correctly it will work great.

I was able to re-do my SAT SIDE of the two external cable connectors to be a straight thru connection all the way back to the antenna panel bypassing any splitters etc...

You can also generally get into the trailer parked under the metal roof pretty easy going through the basement door which has rubber seal on the edges. Other folks come down through the fridge vent.. being under the metal roof you could probably crack a window and come through the edge of that as well...

Drilling through the sides of the trailer is no big deal to mount another TV CONNECTOR but what I don't want to do is mess with the roof.

You could very easy have a RG cable connected to your TV SYSTEM coiled up laying in the basement area and run it outside when you are parked at home to connect up with your outside antenna...

You could even temporarily run this RG cable across the floors and direct connect to your TV when at home if you like...

Just some ideas here

The cable inlet is non amplified (the amp is in the antenna itself)- if you need boosted signal, I would buy a separate booster.
Other than that- it should pass a signal through, when the power button is off.
