  • Description
K40 Trunk Mounted CB Antenna. Designed to be mounted to the lip of a trunk lid for a clean, no-drill installation. This base-loaded CB antenna can be converted into a magnetic antenna, just select the M40 magnet mount attachment on the right side of the page.

Every K40 is exactly the same. Unvarying. Totally consistent. In materials, construction, and most importantly in performance.

That's because we computer design each and every component. And then match and assemble them on a fully automated production line. With tolerances that you just can't get with old-fashioned hand assembly.

The result: Antenna performance that's far and away the best you can buy. At any price.

Used the K40 for about 2 years now. It is a good antenna.

Pros: Small in size, can get it in white or black and reception/transmission is good.

Cons: After 2 years plastic cracked, NOAA weather radio reception wasn't that good and cable seemed a bit small and fragile.

Overall: Good antenna for the money if you just want an antenna that is for CB use only. If your gonna use NOAA radio, might think about a Wilson!
