Congratulations on having selected the 02635 477 MHz
Antenna. This antenna system will allow you to gain
good performance in all types of terrain, when properly
used. The kit contains all components necessary
to install the system, however it does not include a
mounting bracket, since there are many varieties
of these. The type of bracket will depend upon your
application.
Following these instructions will allow your system
to perform to your requirements and meet your
expectations.
This antenna is supplied with a stainless steel base and
spring assembly, a 3 dB Short Antenna, a 6dB longer
antenna, 5 meters of coaxial cable fitted with an FME
female connector a PL-259 plug/adaptor that suits all
477MHz transceivers.
INSTALLATION INSTRuCTIONS
1.0 SELECTING THE POINT OF INSTALLATION
The mounting position of the antenna on the vehicle
will depend on the type of vehicle you have and what
method of fitting you prefer. This antenna is a ground
independent antenna. This means it does not rely on
the vehicle body for its performance. Hence the antenna
can be mounted virtually anywhere on the vehicle and
still perform well. It is preferred, however, to mount
the antenna as high as practicable to achieve the best
results. It is important to remember that the antenna
must be mounted at least 60cm from any vertical metal
objects.
Suggested mounting positions in order of performance
are:
1)
Roof Rack
, using a 02728 Roof-rack Mounting
Bracket.
2)
Roof Gutter,
using a 02726S H/Duty Gutter Bracket.
3)
Truck Mirror
, using a 02728 Mirror Bracket.
4)
Bull Bar
, using a 02730 Bull bar Bracket. This can
be a poor option for trucks, however, a good option for
4WD’s.
5)
Guard
, using a 02734 “Z” Bracket
2.0 FITTING THE BASE TuBE & SPRING ASSEMBLY
The exploded view on left shows the assembly of the
base and spring.
2.1
Fit the antenna base and cable assembly to the
spring base. It is possible to use the antenna without
the spring, however, we highly recommended that the
spring be used in all types of installations. The spring
should be firmly tightened to the base tube. There are
ventilation holes in the base tube, refer to the diagram.
These holes must be clear at all times.
2.2
Remove the nut and washer from the antenna
spring assembly. Feed all of the cable lead through
the hole in the relevant mounting bracket that you will
be using to mount to your vehicle. Locate the base
tube and spring assembly into the bracket. Locate the
washer over the cable followed by the nut. Tightened
the nut with a spanner sufficiently to ensure a solid
mounting. Excessive pressure could cause damage –
DO NOT over tighten.
NOTE: it is important to ensure that the cable
is not crushed, crimped or damaged in any way
throughout the installation.
2.4
Fit the bracket and antenna assembly to the vehicle
according to the selected mounting position.
2.5
Route the cable through the vehicle to the radio
ensuring the cable is not crimped crushed or damaged
in any way.
3.0 FITTING THE ADAPTOR
3.1
Locate the adaptor onto the FME connector end of
the cable lead and screw it home.
3.2
Tighten the nut on the connector with a spanner
sufficiently to ensure connections. DO NOT over tighten
3.3
Connect to the CB radio antenna socket.
INSTRuCTION FOR uSE
This kit comes with two antennas for several
reasons. The shorter 3dB antenna is ideal for city
areas where height in car parks is a concern. The
3dB antenna also provides the best performance
in hilly or mountainous areas. It is convenient as
a backup antenna in case the 6dB antenna is
accidentally broken.
The 6dB antenna will provide the best performance
for long-range flat open terrain. The radiation from
this antenna is best suited to this application.
And may provide degraded performance in
mountainous regions.
It is important to use the correct antenna for
the terrain in which you are travelling to ensure
optimum performance at all times.
WARNING
DO NOT attempt to transmit (use YOuR CB)
until the antenna has been mounted and the
connector has been properly terminated,
otherwise the transceiver could be damaged.

range flat open terrain. The radiation from this
antenna is best suited to this application..
NOTE
:
The antenna
system will work well in all
directions providing there
are no vertical metal
objects in the path of the
radiating signal i.e. the
antenna will work best if
you can see it from all
directions. Keep in mind
that the higher the
mounting positio
ns, the
better it works!
WARNING
DO NOT attempt to Transmit (use YOuR CB) until
the antenna has been mounted and the connector
has been properly terminated, otherwise the
transceiver could be damaged.
This antenna radiates in all
directions. Regardless of
mounting position, unless
obstructed
