The ST'S antenna scrapes the roof of my garage when I pull in. I was thinking of buying a Eurostyle 13" antenna, or maybe just a shorter one for the winter months. Anyone have any issues with the shorter one's. Guy I work with said I would probably loose my AM and some of my FM. I don't listen to AM much, except for the Game Days when I'm on the road. Any thoughts or suggestions would be helpful. Thanks
