If you want to make your radio antenna into a CB antenna you'll need a special converter since they are not on the same frequencies. I've tried them and you might as well just hold a coat hanger out your window, they just don't cut it. Stick to a CB radio antenna since for CB you need every bit of signal you can squeak out the antenna!!

Griff, not sure what you mean but next to the cab like that is a pretty poor location to start with. If I follow you and you want to put the antenna between the metal of the bed and the back of the cab refer back to my coat hanger idea. lol!
