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.
