Procom GF 1804 - Manual (Page 2)

For the antenna to be delivered with silicone glue
to secure the mount using a double-adhesion
procedure, add an M to the antenna designation:
GF 1804M.
INSTALLATION
1. BEFORE INSTALLATION
When selecting mounting location take into consideration: positions of
back view mirror, wiper blade paths and defogger wires (when mounting
on rear window). The driver’s view should not be obstructed.
Max. allowed curvature of the glass surface on the mounting spot is 2
mm deflection per 100 mm length.
Environmental- and car temperature must be above 15° C at installation,
and installation surfaces must be dry and clean.
2. INSTALLATION
3. TUNING INSTRUCTIONS
Insert a forward/reflection-type wattmeter between the transmitter and
the antenna.
Key the transmitter and observe the forward and the reflected power.
Adjust the tuning screw on the matching unit until minimum returned
power is obtained. For duplex operation, the antenna can be off-tuned
slightly to favorize the matching on the RX. Turning the screw clockwise
will shift the antenna resonance to a lower frequency and vice versa.
The SWR on the TX should, however, never exceed 1:1.5.
4. ADHESION ADVICE
It is essential for a good adhesion result that the surfaces are properly
cleaned and dry.
A high application pressure improves the binding power.
Ideal application temperature range is +20° C to +38° C but may be
extended down to +15° C. When applied, binding strength is maintained
between -30° C and +70° C.
Binding power increases considerably with time. To ensure full strength
of the assembly it is recommended to keep the whip off the mount for
24 hours.
To accelerate attainment of full binding power, the joined parts may be
heat-treated with a warm-air gun.
PLEASE NOTE:Do not heat parts to more than 65° C and take care not
to spoil other nearby car parts.
REINSTALLATION KIT
A reinstallation kit including all necessary parts for transfer of the antenna to
another vehicle is available under order No. »GF-RK 900«.
WARNING
SAFETY PRECAUTIONS
Antennas mounted on the windscreen may cause relatively high field
strengths in the passenger cabin and near the dashboard.
1. To prevent health hazard due to RF radiation, persons must not be closer
than 30 cm to the antenna whip (transmitter output power to the matching
unit: 20 watts). (DIN 57 848).
2. The RF signals at the dashboard may cause interference in the car’s
electronic equipment such as broadcast radio, computer automatics, braking
systems, electronic ignition, relays etc. Some cars are more susceptible to
disturbances than others.It is the responsibility of the installer to carry out a
thorough check of the proper functioning under any conditions of such
circuits before finishing installation.
