GF 2/70
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 surfaces
to be glued must be dry and clean.
2. INSTALLATION
Do not use sealer on rubber gasket or other places.
PROCOM A/S reserves the right to
amend specifications without prior notice
3. AFTER INSTALLATION
Allow the silicone gluings to dry off 2 hours at a temperature above 15° C. To ensure full
strength of the glue, it is recommended to keep the whip off the mount for 24 hours.
4. TUNING INSTRUCTIONS
Insert a forward/reflection-type wattmeter between the transmitter and the antenna.
Key the transmitter on the 2 m band and observe the forward and the reflected power.
Adjust the tuning screw marked "2 m" on the matching unit until minimum returned power is
obtained.
Repeat steps •2. and •3. with the transmitter on the 70 cm band and using the tuning screw
marked "70 cm".
Check that the reflected power is still minimum at the 2 m band. Fine-tune using the "2 m"
tuning screw if necessary.
REINSTALLATION KIT
A reinstallation kit including all necessary parts for transfer of the antenna to another vehicle
is available under order No. »GF-RK«.
WARNING
SAFETY PRECAUTIONS
Antennas mounted on the windscreen may cause relatively high field strengths in the
passenger cabin and near the dashboard.
To prevent health hazard due to RF radiation, persons must not be closer than30 cm to the
antenna whip (transmitter output power to the matching unit: 20 W). (DIN 57 848).
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.
The enclosed silicone adhesive contains acetic acid and fungicides. Keep out of reach of
children and dispose properly.
OPERATION USING A DIPLEXER
In case of operating two transceivers on one antenna at the same time, a diplexer, type DIPX
225/330 is necessary to complete the system. The tasks of the diplexer are to protect the two
receiver inputs from being destroyed by the transmitter in the contrary band, and to ensure a
low-loss path between the transceiver and the antenna, which is not loaded by the other
branch. For further details please see the separate data sheet on the DIPX 225/330. The
diplexer fully covers both bands and, consequently, tuning to specific frequencies is not
required.
