Antenna replacement

Has anybody had their antenna break off at the mount on the roof? Mine broke off after the last snow storm. The screw that comes out of the mount broke off in the antenna.

I was wandering if it is difficult to replace the roof mount. My radio reception has suffered a little. If it's too much of a pain to replace, I'm going to wait. I got plenty of cds to listen to.

Thanks for any advice.

You just pry off the interior dome light with a screwdriver, which should access a couple screws that hold the base on. Then it's just unplugging it, and a gasket, and you should be set.
