I have one, yes I think it's worth having one, but that's just because many of the places we go off roading, there is no cell signal. So we have another way to stay in touch with friends or if there's an emergency, we can call back into town. We haven't had to use it in an emergency, but it's been helpful in other ways too. Going down the highway, truckers will call out and inform of traffic issues, accidents, closed roads, road conditions, you name it. One year, coming back from Nashville, we were heading North and about to the boarder when someone called out "Heads up, there's a gator in the hammer lane at mile marker <mm>". I wasn't sure what that meant until I got there and saw a retread from a big rig that came apart and left a huge piece in the middle of the fast lane. This thing took up the entire lane and I had no choice other than to dive into the slow lane between two truckers. I then jumped on 19 and apologized to the trucker behind me for "slamming the front door shut" on him. He replied back that it was understandable and that he knew how much damage that tread would have made to my truck and PUP that we were pulling at the time.
I have a old Midland 77-285 model with a hustler top load antenna.
