The Winegard Sensar antenna was fitted to many caravans and motorhomes for years. Some similar wind-up antennas, including Commander-style units, work in a similar way, but the heads, arms and mounts are not always interchangeable.
If your old antenna struggles with digital TV, poor regional reception or vertical-polarity areas, there are three common upgrade paths: add a Wingman, replace the Sensar head with a Winegard FreeVision retrofit head, or replace the head with a King Jack-style head.
Do the simple checks first. A new antenna head will not fix a broken coax cable, failed booster, bad wall plate, water-damaged connection, wrong polarity, or a TV that has not been retuned for the current area.
For a step-by-step reception check, see our caravan TV reception guide.
The Sensar head is the roof antenna head fitted to the Winegard wind-up arm system. The winder, arms, roof plate, coax cable and 12V wall plate are separate parts of the same antenna system.
That matters because some upgrades replace only the head, while others replace the whole antenna system. A retrofit head is easiest when the existing Winegard arms, roof mount, cable and wall plate are sound.
The Wingman clips onto a compatible Winegard Sensar antenna head. It is the least invasive upgrade because it does not need a new roof hole, new winder or new cable run.
The local Wingman version is identified by NZ-WING on the packaging and is intended for Australian and New Zealand conditions. It mainly improves UHF performance, so it can help where the existing Sensar head is otherwise working but marginal.
Choose this path when the existing Sensar head, booster and cable are working and you want the simplest improvement.
The Winegard FreeVision retrofit kit replaces the existing Sensar head while keeping the Winegard arms, winder, cable and 12V wall plate. It is a better upgrade when the old head is damaged, poor on digital reception, or you want improved horizontal and vertical reception when the antenna is raised.
This is usually the best choice for an older Winegard Sensar setup when you want to keep the roof mechanism and avoid reworking the van interior.
The King Jack digital antenna head can suit some Winegard-style lifter and mast setups. It uses the existing support system in suitable installations, but compatibility depends on the exact mast and base.
This antenna is designed for horizontal signals. If you regularly camp in regional areas using vertical polarity, check whether that limitation suits your travel before choosing this path.
If your van has no roof antenna and you do not want to cut a hole through a pop-top or camper roof, consider a mast or foldaway antenna instead of a wind-up roof system.
A mast antenna can be easier on a pop-top, camper trailer or lightweight roof because it avoids adding a winder through the ceiling. You still need a safe cable path, a suitable wall plate or connection point, and a way to secure the antenna while travelling.
Many caravan antenna systems use a 12V booster or wall plate power supply. If your caravan is wired as 240V only, you still need the correct low-voltage supply for any 12V antenna amplifier. Do not connect a 12V amplifier directly to 240V.
If reception is lost after a branch catches the cable, after water gets into the antenna head, or after a roof repair, check the coax path carefully. A damaged masthead splitter, poor connector, crushed cable or corroded board can stop reception even when the antenna looks fine.
If the roof antenna has no signal but a portable antenna works on the same TV, the TV is probably not the problem. Work backwards through the wall plate, booster, coax cable and antenna head.
