So... I am starting to research cb radios. I understand the different sizes of a CB antenna but is the goal to have a long antenna for range, or a HIGH up antenna. Basically what I am wondering is will a 5 ft antenna mounted to the rear bumper get better reception than a 2" antenna mounted to the roof (assuming they are even). I want the long range of a 5" antenna but I go in parking garages a lot for work and school.
