Respectively disagree that CB's are of no use. The old CB's did NOT have all the functions the new handheld ones have.
I bought this hand held CB to add to my arsenal of being safe while Full-Timing. It sits on the dash, squelch turn down. I can't say enough about this CB.
Here are a few functions included in this handheld CB which is why it is 'always' in my MH.
1. Another form of communication if no cell towers in case of emergency.
2. Traffic. Traffic backup/accidents in REAL TIME from drivers right there AND you can get info from them on where to get off to avoid, etc when RV traveling in unfamiliar areas. Can't get that from your GPS and you don't have to update maps all the time! :W
3. NOAA All Weather
Emergency Radio. This CB comes with NOAA emergency alerts IN REAL TIME. For weather. This saved my hiney twice. Once when unknowingly I was driving right into the path of a tornado, the ER weather radio alarm went off on the CB. This feature alone IMHO is a reason for all RV'ers to have it on board. Especially when you don't always know what county you are driving thru which is how the weather alerts are given on the TV/MH radio.

It comes with a mag mount additional antenna with a very long cord to run out your window. BUT, in the ten years I have had it I have never had the need to use it. The antenna on the CB, and the CB on the dash brought in all I needed.
