You should have a socket that looks like this one 12v outlet, aerial connection, the booster is the little red or black switch to the side, we had 2 aerial outlets the second was a standard outlet on the buffet cupboard inside the door next to bed (16-49-3) the booster has nothing to do with external source from park onsite connections.

Hi,
Just a quick question, I have the same booster Aeriel as quoted, I also have a TV outlet next to the door (inside on a 16.49.30OB).
Am I right to assume that this one is not connected to the Wineyard aerial and only to the Aerial plag on the outside of the van?
