To tell whether your antenna has an amplifier built into it, you will need to be able to get on the roof of the RV. If this is something that you can do safely and comfortably, then raise the antenna and find the “W” shaped hole in the bottom of the antenna housing. Look in this hole, you will find one of three things.1. Nothing or tiny little wire(s)2. A fairly large wire.3. A circuit board.
The first tells that you have a Non-amplified antenna. The other two are amplified.
