I started using a CB radio back in the late 70's. (Think of Smokey and the Bandit.) That's when CB radios were in their heyday. I got my call sign before the FCC stopped requiring them for citizen's band, KAEZ 4492.
These days, I still have a CB in my truck. I only use it for road trips. It's a nice line of communications to have when you're out on an interstate with hundreds of miles to travel. Not a lot of traffic on channel 19 these days. Most truckers have gone cellular and don't chatter much anymore. When you are facing a major slowdown or jam, getting an update from the OTR truckers on the situation is very helpful. You can save hours of delays by picking an alternate route, based on what they say.
This antenna is as good as any driver could want. It has a good base load, eliminating the need for a long whip antenna. The base has a powerful magnet that will NOT be dislodged by the wind. The base is also well sealed, preventing moisture from getting to the wiring. The coax is well made, long enough for any application and the terminal is universal and well made.
I'd recommend getting a tuner and adjusting the height for the most efficient broadcast signal. But, it's great right out of the box.

SWR was WAY off!
I installed this antenna in my 2015 Hyundai Accent and connected it to my inexpensive Uniden PRO505XL 40-Channel CB Radio. Installation was straightforward. Stick the magnet mount antenna on the roof, route the feedline through the car to the radio, and connect it to the SO-239 jack on the back of the radio. However, I did run into some difficulty with adjusting the SWR of the antenna. For those who don't know, when you mash the Push-To-Talk button on the radio a signal is sent out through the air via the antenna. All antennas will reflect some of that signal back into the radio. This ratio of the reflected to radiated signal is called Standing Wave Ratio (SWR.) The theoretically perfect SWR is 1:1 but practically that is impossible. An acceptable ratio is under 2:1 and the antenna must be the correct length to get a good ratio. The instructions that came with the radio discuss how to adjust the antenna length to reduce the SWR. When I first installed the antenna the lowest SWR I could attain by simply adjusting the length of the antenna was 3.5:1. Eventually I was able to get the SWR down to 1.24:1 on channel 17, which is a very good SWR. However, to attain this I had to use a Dremel tool and cut off about 1.5 inches of the antenna. I did this by cutting off about 1/4 inch at a time and then using my antenna analyzer to check the SWR. I had the tools and the test equipment so it was simple. But for those who are looking for an out-of-box solution you may need to enlist the help of someone with an SWR meter.
