shark fin antenna for 9-3
 

And, while I'm at it, wife's car also has broken shark fin antenna, and her FM is out. I've read varying things on the shark fin only doing sat or On Star, or it is the FM antenna. Confusing. Is it the main FM antenna on some cars? Or am I looking at a conincidental drop when it broke? What am I looking for, for the lowest price option, for a 04 Linear 9-3, with no OnStar or sat?
