Other CB antennas are handmade. That means they're hand wound. Hand soldered. And hand glued. With so much variation, no two can ever be exactly alike. 

But 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. And that means whatever road you travel, you can use your K40 with that wonderful feeling of supreme confidence. Guaranteed.
