mine did a similar thing, even did it at the dealership when i was about to buy the car. i asked the sales guy why it wouldn't go down all the way (stayed like a foot up) and he said it's the way the newer antennas are!! i was like you bastrd liar! anyway, if you pull up on the antenna, chances are there's a bend at the bottom that is hidden beneath the fender. mine looked straight when it was up all the way but i pulled up and like 2 inches of antenna came out of the fender and there was a nice bend there.
