WOLF RIVER COILS Silver Bullet HV User manual

Thank you for purchasing the Wolf River Coil Silver Bullet HV Wire
Antenna.
The
Silver Bullet
HV Wire Antenna was developed as a simple
portable wire antenna capable of operating the lower amateur
frequency without the need of an antenna tuner. The ante
nna
will resonate 10.2 MHz thru 3.5 MHz. The antenna can be
mounted either horizontal or vertical. Depending on the
installation a ground counter poise may be necessary. A 4 foot
ground rod has proven to work very well for both antenna
mounting and coun
terpoise. A 3/16 hole is required thru the
ground rod for direct mounting of the coil ground side and
support.
Your antenna comes with a Sil
ver Bullet 1.25 coil, 20 feet of antenna wire and
antenna insulator.
Simply attached the antenna wire to the top
of the coil by removing
the 5/8 nut slipping the antenna terminal ring over the 5/8 stud and
replacing the 5/8 nut. You can hand tighten for portable operation.
Add the coax braid to the
negative side of the antenna coil
(this is the side without any
wires connected to the
mounting screw), then add the coax center conductor to
the coil (this is the side with the coil lead and coupling
wire attached).
If necessary a ground counterpoise can
also be attached to the negative side of the coil.
Lastly
attach a support to the antenna insulator to a support that
can elevate the antenna (like a tree limb). For attic installation you
can attach string or other non
-
conductive support to mount the
coil and wire.

for mounting ideas.

Once your antenna is mounted and secure simply tune your radio to the desire operation
frequency and slid the tuning coupler up and down the coil until maximum noise or signal is
heard. An an
tenna analyzer can aid in finding the lowest SWR for the desired frequency. A
SWR of 1.4 or less should be obtainable. Once you find you desired coil setting a marker can
be used to mark the coil for the coupler location for easy tuning the next time you
use your
antenna. Tune the coupler near the top of the coil for 30 and 40 meters, and towards the
bottom of the coil for 80 meters. 60 meters is halfway in the middle of the coil. You may need
to hold the base of the coil with one hand while sliding th
e tuning coupler up and down on the
coil.
