I got tired of the long whip antenna trying to poke my eye out when I walked around the back of the bike so I replaced it with a generic flexible 14 inch rubber antenna. This is available at either Autozone or Advance Auto and probably other auto parts stores. Very enexpensive. It comes with different adaptors for the different threads but they don't work. The threds in the mount on the XC are the same as the new antenna. I found a 2 1/2 inch long screw that had the right threads and cut the head off. I then put some locktite on the screw and put it into the antenna. After it set up I screwed it into the antenna mount on the bike and the reception was just as good if not better. I believe the package said it was an amplified antenna.
