The "Wilson Creek Classic" which covers 80/40/20 meters and is pre-tuned for 3.85, 7.225, and 14.250 Mhz. It is only 98 ft long and will handle legal limit of power. Works well with 75 or 52 ohm feed line between 75 and 100ft long. Made in Texas
WILSON CREEK CLASSIC :
Specifications: Assembled Wire Antenna: Antenna Type: Multi-band,
coaxial trap dipole resonant Antenna; Power Rating: 1,500 W, Maximum
Wire Antenna Length: 98.00 ft. Antenna Tuner not required by can be used:
Feedline Connection Type: UHF female, SO-239; Recommended
Feedpoint Height: 35 ft.
Antenna can be used as a flat top dipole or an inverted vee
configuaration. Both will yield good results. We recommend a good
earth ground and a 50 ohm feedline for best results.
TUNING INSTRUCTIONS WILSON CRK CLASSIC
The Wilson Creek Classic comes pre-tuned for 3.8, 7.2, and 14.25 Mhz. However,
many Hams prefer to customize their antennas to favor certain portions of the
band. In some cases the antenna may have to be adjusted to compensate for
location and or localized interactions from nearby objects.
Here is how it is done: To raise the resonant frequency on 40 meters you will
have to remove some of the wire at point A on the drawing. You should not have
to remove but approx 3-6 inches of wire. This will raise the resonant frequency
from the 7.2 Mhz to approx 7.250 or 7.275. Should you want to lower the
resonant frequency you will need to add wire at point A on the drawing.
***Note*** Removing some of the wire at point A on the drawing will also raise
the resonant frequency on 80 meters. If needed, you can add wire at point B on
the drawing and this will in effect lower the 80 meter point of resonance. You can
also raise the resonant frequency on 80 meters by removing wire at point B. It
will have no effect on adjustments on 40 meters.
20 meters should really need no adjustment however if it can be adjusted by
adding or reducing it’s length. This is done at point C on the drawing. Add or
reduce it’s length by no more than 1 inch at a time.
Remember: To raise the point of resonance you shorten the antenna length. To
Lower the point of resonance you lengthen the antenna.
