Do all campers have a switch to amplify antenna?

I can only speak for mine. To use the campground cable, I have to connect it to the outside cable input, then push the lighted switch to change the tv to the outside input.

Then I have to change the tv set's input to cable and scan the input.

To change back, I push the antenna switch, the light comes on, the antenna switches back to the roof antenna. Then I have to select over the air input and scan for channels.
