A lot of 4x4 (=16) guys and gals use cb to talk whilst trail riding. Had a Francis Wheeler Dealer .25wl antennae on the Samurai, people told me it looked like an rc car.
Ahh, yes, the 102" (or 108") stainless steel whip, 1/4 wave for CB. Pretty hard to beat as a mobile antenna, especially with the massive spring at the bottom.
Yes, you can still buy CB radios and yes people still use CB radios. Here are some of the newer CB radios on the market:
Ranger (RCI) Superstar SS-158FB4. The SS 158FB4 is the latest incarnation of the famous Superstar 3900 series radios, this all-mode AM/FM/SSB beast includes a built-in amplifier and is rated at 100w carrier/400w PEP AM/SSB and covers has 12 bands to choose from covering 24.265 MHz to 29.655 MHz. An easy mod can change that to 24.715 MHz to 30.105 MHz, giving the operator full coverage of the 12 meter ham band, the 10 meter ham band, the CB band and all frequencies in between:
