K40 Trucker Antennas
K40 Trucker Antennas
Per the manufacturer the K40 Trucker Antenna design specs are as follows:
Center Loaded CB/Weather Band Antenna
5 Year Warranty, 26-30 MHz
1.6 MHz bandwith
1/4 wave length design

Tunable design
In recent testing by the U.S. Dept of Commerce, the K40 Trucker 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
Because the RF signal travels only 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.
