Antennas, well where you plan to mount it, determines what you can pick from. Most antennas will all hear about the same. 1/4 wave , base loaded antenna mounted on the truck lid works good. Alittle better, go with a roof mount, . The local trunk stop should have plenty. One of the best I have used was a Larsen base load NMO 27. Used for a couple of years. Went to a longer antenna, bigger is better in CB antennas, it was a Gray Francis antenna. It was about 10-13" shorter than a full quarter wave 108" whip. If I was driving in western Kansas , that was the antenna of choice. It was mounted on a ball mount up by the rear car window high on the fender. So shorter, more convenient, shorter range. Longer antennas, greater range, harder to park in garages.
