GF 230-DAB

0 dB Mobile GlassFix® Antenna for the DAB Band

  • Half-wave, 0 dB mobile antenna for the DAB band using the GlassFix® mounting principle.
  • Mounting on car window glass – no holes required.

NOTE

GF antennas are not suitable for car models with windows that have heat reflective coating.

Description

  • 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.
  • Easy removable whip for car wash.
  • Swivel joint for 180° angle adjustment.
  • If removal of antenna installation is necessary, a quick dismantling procedure leaves no trace of the installation.

ASSEMBLY DETAILS

 

 

 

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. INSTALLATIONS

 

 

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«.

 

 

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
    than 30 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.
