My mom purchased this antenna for me for my 02 trailblazer. When she put shipping info in she put the wrong zip code. RCR was very quick to contact her and have her give the right zip code. Easiest antenna I have put on yet. No tuning of antenna required which I had to do with the lil wil I had.

5 stars for sure

I would like to thank you for your quick shipment of my new K-40 Magnetic base antenna. I only use my CB during hunting season. I have had great reception and transmission with my new antenna. I have an older version which is fiberglass and spring loaded which I can easily change if needed with the quarter turn release. I have used K-40 antenna products for the past 25 years. Great product and great service from Right Channel Radios.

Thanks Again For Great Service.

Hands down, the best mobile antenna next to a stainless steel whip or a monkey made. I have had mine for almost 7 years and it has been on 3 different cars. performs like the day I bought it new. I have had to use tape to cover a few nicks on the coax over the years, but other than that, it has been flawless.

I initially set the SWRs when I bought the unit 7 years ago, and they have gone unchanged since then. Two different radios have been used with this, a Galaxy DX88HL and my current rig, a Galaxy Pluto. The firm magnet has very positive engagement, and will stay on your car at 100 mph with no problems. the wide magnet base provides for a good ground plane, so there is usually no issues with feedback with radios that have echo boards.

The only con about this setup is I wish K40 had included a small locking plastic cap to make the base water tight when the load was not installed. It would not have taken much engineering to make a plastic cap with the same locking key system like the load has.

Well worth the money. Great product and performance. They are rated at 500 watts, so don't go too wild with the foot warmers.
