FireStik (FG4-648-B) - FS II No-Groundplane CB Antenna
Kit, Tunable-Tip, Fiberglass, 4ft, Black, 5/8 Wave, 100
Watt, Top Loaded, with Mount, Spring and NGP Coax
Description:
PURPOSE: The FGX-648 (where X = antenna length in
feet) series, 'No ground plane" (NGP) CB antenna
kits were specifically designed to solve the problems
associated with the lack of ground plane (counterpoise).
This normally occurs on vehicles constructed of plastic,
fiberglass, wood or aluminum. This includes, but is not
limited to, motorhomes, boats, automobiles and 18-wheeler
trucks. Ground plane problems typically show up in the
form of high standing wave ratio (SWR) and poor
performance. The isolated ground plane that is built into
the FGX-648 series kits can also eliminate problems on
metal base vehicles that lack the sufficient ground plane
for proper operation. This could be due to the size of
available ground plane (ATV, bicycle, motorcycle,
wheelchair, etc.), or because the operator chooses to
mount the antenna in a location that is unable too
properly take advantage of available ground plane. The
versatility of these kits goes way beyond the normal
expected uses of a typical mobile antenna kit. Aside from
vehicular installations, these kits can be mounted on a
pack frame for hunting or Search and Rescue operations.
Apartment dwellers can mount them on a balcony railing,
or a temporary base station can set up in the forest
using a tree for a tower.
ANTENNA: The antennas used in these kits utilize
the same 5/8 wave design as the patented FireStik II
tunable tip antennas. The antenna's frequency is
altered in order to maintain a desirable center band
position when used with the tuned coaxial feedline.
Accordingly, these antennas may only be used with the
FireStik NGP cable. The core material is a 3/8-inch
(0.375" or 10mm) diameter reinforced plastic
(fiberglass). The custom blended formula offers a
preferred balance of flexibility and strength. The chrome
plated machine brass mounting base has standard
3/8"-24 threads. A high efficiency, voltage
increasing helical wind is utilized. Heavy insulated
copper wire is used to guard against shorted coils and
corrosion induced resistance commonly found on
non-FireStik brand antennas. The antenna used in these
kits have FireStik's patented "no tools
required" tunable tip for fast and easy SWR
adjustments. The rated wattage for these kits is 100
watts. Each antenna is covered with a static reducing,
heavy PVC shrink tubing with both pigment and UV
stabilizers mixed in. Available colors are black or white
with a red tip or, red or blue with a white tip.
COAXIAL FEEDLINE: The seventeen-foot (5.2 M)
coaxial cable used in these kits is of the highest
quality. As a matter of fact ... the NGP cable assembly
utilizes a custom manufactured coaxial cable that can
only be found at FireStik. Unable to find the performance
characteristics in any of the commercially available
coaxial cable ... FireStik designed their own. First they
used a multi-wire stranded center conductor to the
prevent breakage that can occur with solid center
conductor cable. A condition known as "cold
working" occurs where vibration is present and this
action can cause solid conductors to become brittle and
eventually break. Surrounding the center conductor is a
long life, flexible, polyethylene insulation. Since
shielding is extremely critical on NGP systems, FireStik
used a double shield around the center conductor. First,
a 100% aluminum tape covers the center conductor
insulator and then a copper wire braid (averages 95%
coverage versus the industry standard of 70%) is applied
over the aluminum tape. The coaxial feedline, besides
being the conduit for the signal to reach the antenna,
serves as a tuned circuit that creates the necessary
counterpoise. If a longer cable length is required, the
user may add standard RG-58 A/U cable between the radio
and system cable, preferably in lengths that are
multiples of nine feet. Because it is a tuned circuit,
the length cannot be reduced without causing
non-repairable damage. Should the cable become damaged,
order replacement cable model K-8NGP.
MOUNT, SPRING AND HARDWARE: To compliment the
quality of the antenna and feedline, the mount used in
these kits is the FireStik stainless steel, 3-way 90
Degree angle mount. Mounting options are, 1) any vertical
bar, rail or post, or 2) any horizontal bar, rail or
post, and 3) any flat vertical surface such as the side
of the vehicle. A stainless steel spring with machined
brass ends acts as the coupling between the antenna and
the feedline.
ADDITIONAL FEATURES: Each kit includes a FREE
microphone hanger and comes complete with user
installation documentation.
And don't forget ... ALL antennas, regardless of
style or manufacturer, MUST be tuned after installation
on the vehicle. Transmitting antennas are not
"plug-n-play" devices.
