Wilson W1000 RT 62" Roof Mount Antenna
This is an oversize antenna. There is an extra $8.50 handling charge on UPS shipments.
The Wilson 1000's higher gain performance is a result of several new design developments that bring to you the most powerful CB base loaded antenna available in its price range.
A large portion of the power that goes into a typical base loaded CB antenna is lost as heat in the coil and as dielectric heat loss in the plastic inside the coil form. Many CB antennas lose more than 50% of the power put into them. The power is wasted as heat loss and not radiated as radio waves. Another weak link in other CB antennas is the capacitor used to match the coax to the antenna, which is a cheap and easy way to make the SWR look good, but has lots of power loss, plus blows out when high power is applied to it.
The first priority was to reduce the dielectric loss by removing as much of the plastic inside the coil as possible. This was accomplished by suspending the coil in air, supported only at four small points, 90 degrees apart, in effect removing 95% of the plastic from the inside surface of the coil. This reduced the dielectric loss to a negligible amount.
The second priority was to get rid of the resistive heat losses in the coil. Since most of the RF energy at 27 MHz travels on the surface of the wire, it was decided to increase the surface area by making the diameter of the wire larger 10 GA copper. Since silver is a much better conductor than copper, although very expensive, the wire was heavily silver plated. This reduced the resistive loss to a minimum.
Finally, to get rid of the losses in the matching between the coax and the loading coil, the lossy capacitor was eliminated and a difficult but more efficient means of coupling the antenna was used. A Scalar Network Analyzer was used to determine the very precise point to direct match the coil with the coax and obtain the best match with maximum power transfer, which gives the 3000 watts of power handling capability.
