I have been trying to find a shorter antenna too. I did find a Shark Fin style replacement: http://www.hyundai-forums.com/index.php?sh...c=43748&hl=
I may just get another one of the same antennas and cut it down to the size I want. I'll put a vacuum cap on it after I cut it down. I don't listen to the radio, I just use the USB port and CD's.
