THE Wilson "500" PERFORMS BETTER
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
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 and your Wilson 500 is guaranteed to outperform any CB
mobile antenna (except the Wilson 1000 or 5000), or your money back.
*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. This
means that the Wilson 500 gives you 28% more gain on both transmit
GUARANTEE: The Wilson 500 CB antenna will transmit
and receive farther than the antenna it replaces or your money
back. This guarantee is good for 15 days from the date of purchase
at the original purchase point only, and with dated sales receipt.
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
value and performance, you can't beat a Wilson CB antenna
the ultimate in performance and power handling see the Wilson 5000
base load antenna.
Short load - Info and specifications
height is a concern and you desire a shorter antenna, the Wilson
Short Load is the answer. Designed for maximum efficiency, it
is only 39 inches long and replaces the 62" whip that is standard
for the Wilson 1000 and the Wilson 5000. The
Short Load adapts to the Wilson 500 and all models of the Wilson
1000, 5000, Trucker 2000 and the Trucker 5000. The band width
will still be wide enough for most uses - 1-1.2 MHz, and the
power handling is 500 watts. The Wilson Short Load is the perfect
solution for individuals that require performance and desire
a shorter antenna.
