In this video, I demo how I maintain our Keystone Cougar trailers Winegard batwing style TV antenna.
Our rig has the standard Winegard bat-wing style, hand crank TV antenna. The manual states to lubricate it twice a year with silicone spray. It is important to use silicone lubricant because the crankshaft has a rubber O-ring seal in it. Silicone is safe on rubber and will lubricate the O-ring. Other types of lubricants may damage the rubber seal and cause possible leaks when it rains hard.
It takes a few trips to the roof and back, but it gives me a chance to check the other sealants up there anyway.
Helpful link for finding Over the Air TV signals – http://tvfool.com/ It shows stations in your locations and where to point the antenna.
