FireStik (FS4-64A9A-B) - FS II 40 Channel Plus Co-Phase
CB Antenna Kit, Tunable Tips, Fiberglass, 4ft, Black, 5/8
Wave, Top Loaded, With Dual 3-Way Mounting Brackets,
Springs and Co-Phase
Description:
This high performance CB antenna kit comes complete with
4 foot antennas and 3-way mounting brackets that will
allow you to mount the antennas on a vertical or
horizontal mirror arm or rail as well as directly to any
flat vertical surface. The kits also includes
FireStik's dual-18 foot Fire-Flex cophase harness
made from top grade RG-59A/U coaxial cable complete with
three screw-on PL-259 connections. And, as a bonus for
purchasing a complete kit, FireStik throws in 2 FREE
stainless steel springs and a FREE microphone hanger.
Co-phased (or dual) antennas are normally chosen for use
by vehicle owners that spend much of their time on the
interstate highways. Dual antenna systems create a
transmission pattern that has increased field strength
directly in front and behind the vehicle. This is
especially helpful on vehicles pulling large trailers
that tend to shield the antennas radiated energy in one
or more directions. Co-phase antenna systems are also
useful on vehicles that are lacking in ground plane
(composite materials, etc.) as they use the magnetic
field from one another as the RF field counterpoise.
However, to work properly the antenna mounts MUST have a
good chassis ground and the antennas MUST have
unobstructed line-of-site between the top 50% or more of
the antennas overall length.
There is also much talk regarding the spacing between the
antennas. Many people believe that dual antennas will not
work unless they are spaced 1/4 wave length (approx 9ft)
apart. While this may be true to the nth degree, it does
not mean that they will not work with lesser spacing. The
spacing will have some effect on the radiation pattern
but short of testing every installation and weighing the
results against a 9ft spaced installation on the same
vehicle, it cannot be assumed that the spacing is better
or worse for performance on that particular vehicle.
FireStik has seen satisfactory results with antennas
spaced as close as 5ft apart.
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.
