I got a GS racing antenna tube before and couldn't figure out how to use it. Theres no where on it for the wire to go through. Drilling a hole in an antenna breaks it.
Anyway, i cut the antenna near the mount, and slipped a piece of fuel line over it, and put the wire through that, and put it on the antenna. And of course my antenna was cracked so i just cut it on the crank, and i dont need a new one now
