I have been using CB's for years. I'm not interested in talking to someone 10 miles away. So I use a glass mount with a short antenna. Yeah, it only travels maybe 3 miles but it also doesn't pick up all the noise that all those transmissions produce. It is hardly noticeable and does a great job. I tucked the cable under the interior trim and stuck the small box on my rear window, as high up as it could go. I have had no problems with it since I installed some 11 years ago! I find that the truckers don't talk on CB's quite as much as they used to. But when they do....
That's what the squelch knob is for.
It helps to keep me awake and let's me know which lane to get in if there is a slow down in traffic. I don't talk on it much, just listen mainly.
