If you go with a smaller unit like the unidenpro 510, she won't even notice it is there. I will have to post a shot of where I put my mic.
Also, one thing I wish that I had done was getting a pro520 or better yet a 538 (versus my uniden pro 510). The uniden 510 doesn't have gain, nor does is have sideband (which I don't even know what that is), but I really wish that I had the waether channels which I believe are available on the 538. The 520 is maybe $10 more and the 538 is another $10 on the 520.... I paid $40 for my CB.
I will also have to get a shot of how I have done my antenna, it's like the kilby setup, and I am pleased with it. (removed one of the lug nius of the rear spare, and threaded a bar 1/2-20 with a taper, and clamped my bracket to it.... I just need a heavier duty spring.
Also, if you are going with a firestick, MAKE SURE that it shows the screw in the top, and that the packaging DOES NOT say "cut to tune". I am pleased with my setup, and after using a radioshack magnetic base antenna, I will say that the firestick is a nice antenna.
