We use to have 2 portable hand held CB's with the magnet antenna mount back in the early 1980's. Two things changed all of that. 1). They quit using steel for the roof and fenders of automobiles, went to aluminum, and finally went to fiberglass, and now ... who know what they are using, but it sure isn't steel. 2) the invention of the cell phone. By 1990, our CB days were over. The first cell phone we had was a big old clunky thing about the size of a military 2 way radio, that came with it's own carrying case, and plugged into your cigarette lighter. We thought that was fantastic technology back then! And the CB ended up in the attic, ended up rusting, ended up in the trash.
I haven't thought about CB usage in ... what ... 24 years at least?
