No CB on mine (or my buddy's TJ) but instead, Btech UV25 mobile units with an external Comet dual band antenna. Those inexpensive Chinese radios operate within designated FCC band frequencies and beyond those, allowing GMRS as well as Rugged Radio "race frequencies". With dual band and all regional repeater frequencies programmed (keep a cheat sheet for quick reference), we have the ability to reach out well beyond short distance range of CB or GMRS in the case of a medical emergency or to report a wildfire. We use the same setups in our Can-Am Maverick Sport Xrc units (in combo with headsets connected to passive junction boxes). IMO, CB (or GMRS) units are OK for group communication but fall well short of using legal FCC repeaters in combo with a HAM license. Although reporting such emergencies is legal without an FCC license, understanding communication basics and how to obtain and program repeater frequencies has a learning curve that is well worth the time and effort...
