I had a cb and 1 or 2 antennas back in the day and had never tuned one. Bought a '90 Kawasaki Voyager 12 touring bike in late 2002. It had a cb on it. Decided to tune the antenna at one point, since the Clarion CB components on that bike had become somewhat scarce and pricey if you needed a part. Took a half hour or so, trimming the upper portion and rechecking, going slow so I didn't cut it too short. Bought another Voyager and it had a CB on it, but an aftermarket antenna. Tuned it, no problem. Eventually, the Clarion antenna base on the first bike fatigued/failed, so had to replace it with an aftermarket antenna also. The aftermarket antennas were Chinese, or worse than Chinese, and wiggled more than they should at freeway speeds. Eventually, you would get to your destination, but the antenna tip would be somewhere 300 miles back down the road having broken off due to metal fatigue. I got good at checking SWR and trimming cheap antenna tops.
Enter the Firestik II. I got tired of replacing antenna tips on the motorcycle and wanted to experiment with other options. The Firestik II and the Wilson Flex, both have tunable tips, where they have essentially, a screw in the end of the antenna where you just turn it out or turn it in (in small increments) to tune the SWR. Takes like 5 minutes. The Firestik was too heavy for the bike's fragile antenna mount and the Flex just has horrible SWR due to the flex. (unless I just got a bad one). So, back to the aftermarket antennas. I got smart and pre-tuned a replacement tip, and zip-tied it to the bottom of the trunk/tourpack. The Firestik is what I put on my TJ and it will be going to Moab.
Not sure you can get 12 or 17 Jeepers on a conference call for a 2 hour trail run, but for emergencies, that's good to know.
One could buy the GMRS radio and just listen on it, and not have to pay the license fee (if their conscience was the type that it might bug them, or if they're the type that always get busted, even when they're not guilty of anything). And like mentioned above, if everyone is on the FRS channels, then I'd be less than thrilled about having paid for the license when it could have paid for 2 tanks of gas instead.
