0 dB Mobile GlassFix® Antenna for the 450 MHz Band
DESCRIPTION
Half-wave, 0 dB mobile antenna for the 450 MHz band using the GlassFix® mounting
principle.
Mounting on car window glass – no holes required.
Double-adhesion procedure ensures fast and reliable fixing.
Internal matching unit feeds external antenna through window glass.
Half-wave design – no ground plane required.
High positioning gives performance equal to conventionally mounted car roof antenna.
FME FastCabling system (cable to be ordered separately).
Simple tuning procedure by means of tuning screw on matching unit.
Easily removable whip for cleaning in car-washing machine.
Swivel joint for 180° angle adjustment.
If removal of antenna installation is necessary, a quick dismantling procedure leaves no
trace of the installation.
NOTE
GF antennas are not suitable for car models with windows having heat reflective
coating.

1. BEFORE INSTALLATION
When selecting mounting location take into consideration: positions of back view mirror,
wiper blade paths and defrosting 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.
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 and observe the forward and the reflected power.
Adjust the tuning screw on the matching unit until minimum returned power is obtained.
REINSTALLATION KIT
A reinstallation kit including all necessary parts for transfer of the antenna to another vehicle
is available under order No. »GF-RK« (130000329).
WARING
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 closer than 30 cm to
the antenna whip (transmitter output power to the matching unit: 20 W). (DIN 57 848).
2. The RF signals at the dashboard may cause interference in 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 supplied silicone adhesive contains acetic acid and fungicides. Keep out of reach of
children and dispose properly.
