TV signals won't "penetrate through solid objects"...

That said, if you look at the roof of your RV, the antenna location is going to be behind something solid in at least one direction on almost all RV rooftops. That was the purpose of the older "crank up Winegard wingman antenna"... It got the antenna "up above the obstructions". It has an electronic amplifier (booster) in the antenna head. The power for that amplifier is provided through the coax cable that runs from "that little green light/switch" up thorough the roof to the antenna head.

If you are having problems with your Winegard wingman, it may be a loose connection, a power problem or the amplifier may have "bit the dust"...

Choosing to replace it with a "low mount antenna" may work well if the "stuff on your roof" is situated so that you can locate the antenna in a place where it's not blocked in any direction... Otherwise, having the ability to "get the antenna above the obstructions" is critical to getting TV reception from a station in that direction if you're camped in a "fringe area"....

Don't sell the "old technology" short. Many (maybe even most) reviews are positive for the "crank up Winegard" The same can't be said for most of the "low mount replacements."
