  Cut-a-way photo shows K40 out performs its competition

Because the RF signal travels on the surface of the wire, the larger the surface area (skin effect), the lower the resistance. The lower the resistance, the higher the efficiency of the antenna. Higher efficiency means less RF signal loss and more gain. Simply put, you talk further and receive clearer!

  Government testing proves K40 has more gain on every channel

In recent testing by the U.S. Dept. of Commerce, the K40 Trucker Antenna outperformed the Wilson 2000 in gain, VSWR and bandwidth on all 40 channels. Testing was performed by the National Institute of Standards and Technology- the same agency whose U.S. Atomic Clock is the world standard for all computer clocks and the Global Positioning System.
