KING REPLACEMENT HD ANTENNA

and just so you know, there is no such thing as an "HD" antenna. that's pure snake oil.

You may have a fuse that has blown which would not allow your 12 volt amplifier to supply power up through the coax to your antenna.
The King antenna used to come with it's own 12 volt power supply that you would use if your 12 volts is NOT available through an existing amplifier.
The King antenna is far superior to my old batwing which was a rattling hunk of aluminum pieces.

If the "wine-guard windup" is the Sensar (AKA Batwing) you most likely already have 12 volts going up the coax. You should have a wall plate near your TV where your coax attaches to. If there is an on/off button and an LED that lights when it's in the ON position, you should be all set. Just replace the Winegard antenna with the Jack.

The big question is why do you want to replace the antenna? The Batwing is considered the best RV antenna. If you are having poor reception, your problem most likely is not the antenna.

The Winegard SensarPro will insert power into the antenna coax, plus help you peak the signal. I added one to our amplified Phaeton's batwing antenna that had lost it's power source, now get a stronger digital signal. Paid about $70 at an RV club show.
