Here is a brief overview about CBs you might find helpful and here are some great CB resources.You need as much ground plane as you can get -- which is why roof-top mounts work better.As for the mounting location... back passenger quarter panel!The coax quality is probably fine, but you want the shortest possible run -- and the coax needs to be tuned to the radio as well.I'm also using a cheapo 20' coax from Radio shack... which I've also learned might be too long and of poor quality!
I am sure it will work fine.The Radio seems nice for what it its... just not worth anything if the max range is 75 yards with clear line of sight!Fry's carries the meters -- but you really don't need one. Look up CB in your local yellow pages -- I am sure there is a store nearby. Or a truck stop!How do I go about getting the Radio and Antenna tuned? Any ideas on where I can get a SWR meter?
Here is an article that Chuck Kopelson wrote -- that is a great overview about CB's and might be helpful to you as well.
