Do not waist your money on the Wineguard pancake antenna!
I thought was good idea, as not lowering or raising would be nice.
It works about as good as if I knocked off the batwing!
The old style fold ups are interesting too...add a amp and you would be set.
I patched hole by cutting a piece out to match attachment area of old antenna, made three non-touching doughnut circles with sealer, and pop-riveted it in place.
Used bytle<sp sealer from Depot, is gray and flows nice.
Is made for exterior panels that flex.
