The Wilson 500’s higher
gain performance for an economical antenna is the result of
several design modifications to the famous Wilson 1000. Using the
basic design of the W-1000, Wilson is able to produce a mid priced
magnetic antenna with great performance characteristics. This
produced 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.
Wilson’s 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 12 gauge copper.
Finally, to get rid of the losses in the matching
between the coax and the loading coil, the lossy capacitor was
eliminated and a more 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. The combination of
all these accumulated design points allows the W-500 to have a 2,000
watt power rating with a 20-25% increase in performance over the
Little Wil.
So far you have read about why the Wilson 500 performs
better, but the Wilson 500 is also a very rugged antenna. It is made
with Thermoplastic. It costs a lot more, but it’s the best available.
All of these are the reasons you get a 2-year warranty.).
For an even shorter antenna you can install
this 36" "Short
Load" whip in place of the factory 54" whip. |

*TEST RESULTS:
Test by Dr. Dwight Heim, Professor Emeritus, University of Michigan,
shows that the Wilson 500 magnetic mount has 28% more power gain than
the American K40 CB Antenna (on channel 40). This means that the
Wilson 500 gives you 28% more gain on both transmit and receive, on
channel 40.
ANTENNA POWER GAIN : the amount of
improvement in power amplification over another antenna. The higher
gain antenna will transmit & receive farther, but the actual distance
will vary depending on the gain, ground terrain and other
environmental factors. Individual test results may vary due to the
vehicle's ground plane and matching configuration.
