I travel through the mountains each time I go to Florida. This antenna was not big enough to handle the hills and vallies.

If you have a small car, such as my Mazda, it is easy to install and route to the CB. I have mounted mine on the trunk, and it can be removed if necessary. The magnet is of good strength and works well. It has also taken a few knocks from my oak tree that branches out over my drive way.
So far, I am pleased with its performance.

Base loaded antennas are not worth a damn! center loaded like a Wilson trucker 2000/5000 or top loaded like a Firestik II will out perform this antenna 70%.

well engineered antenna for CB use. Requires knowledge of SWR for optimum assembly and use. Stable platform.Reasonable pricing.

So I purchased a handheld CB for emergency purposes, and I also purchased this antenna. I must say, this antenna is amazing in quality and range. It allowed me to talk to trucks from my university campus all the way across the river, out to US-22 where the Lehigh Valley mall is. That is some incredible range considering it is hilly with lots of large metal buildings around.

Anyways, I recommend this antenna to anyone with a CB, even a handheld. I know many people purchase a handheld CB for emergencies in the car, but many people don't purchase external antennas. Note to all of those people...having the CB in the car will diminish the transmitting range to almost nothing. Besides, if you have an emergency, do you really want to stand on top of your car and call for help b/c your manufacturer supplied antenna is a piece of junk? While pulled over you could set this antenna on top of your car and call for help. Or, whenever you are driving on a long trip, put it on top of your car ahead of time. It's also great for killing time and talking to people. I also purchased the Cobra telescoping antenna for true emergency purposes if I am separated from my vehicle and far from the high-way, I need to reach someone etc.

Overall...good to have...and it works on highways going over 80mph!
