I will check with my CB shop about that wire. I originally wanted the FS2, but he was out of stock. So I ended up getting the Wilson KW2 which looks just like the FS2. It was more expensive, the dealer told me its a better antenna. Do you have the Cobra 75? If so, where did you mount the antenna connector box?
