If it is (was) a little whip antenna like on my North Trail, I think it just screws into the base. Mine looks like the one I bought at O'Reilly auto parts for my golf cart. You'll probably have to buy the base and everything, but hopefully the antenna will just screw into the existing base. I had read on this forum somewhere that someone had found that their antenna was very loose. I then checked mine and sure enough, I had to screw it down.
