This Winegard Retro Fit Kit winds-up and rotates manually from inside your RV (as per your original Sensar), however the advantage of this model over the SenSar is that it collects vertical and horizontal signals that covers all Australian Transmitter styles.
This antenna has been extensively developed in the United States with a great deal of Australian input to ensure you receive great picture quality anywhere in Australia.
Warning: This RetroFit Kit requires you to already have a Winegard Sensar installed. This replaces the elevating arm and antenna head.
ANTENNATEK Signal Commander , owners have also reported that replacing the elevating gear with a winegard Elevating gear - NOW INCLUDED will allow retrofit to the Commander antenna. You will need to reuse your connecting pin at the pivot point.
