I have a couple of CBs that I picked up for not too much. I put one in my car, its the Cobra 19 Ultra III. I haven't messed with it much and I have the recommended antenna from Cobra(I think its the HG A1500 model its about 3ft. tall). I have a SWR from radio shack too. If anyone would be so kind as to walk me through the basic technical concepts that I am overlooking, I'd be most appreciative.

Thank You

P.S. If you know of any good CB shops around Charlotte NC, please let me know.
