Thanks to everybody who responded to this post so far. This is all good stuff to know, as not only will I be using my truck out at Moab but I plan on using it regularly at a ranch where cellphone coverage is nonexistant and having a CB for convenience and to communicate in times of emergency would be a great thing. If I do mount the antenna on the roof, then how will the addition of a rack/basket such as the Load Warrior compromise the antenna?
