Reinstallation Kit for the GF 900/1800 GlassFix® Antenna

DESCRIPTION

The “GF-RK 900/1800” GlassFix® reinstallation kit contains all new parts

necessary to reinstall the GF 900/1800 GlassFix® antenna. The

following tools are necessary: A knife with a long, bendable blade.

Acetone and a dry cloth.

NOTE

GF antennas are not suitable for car models with windows

that have heat reflective coating.

ORDERING DESIGNATION

TYPE NO. PRODUCT NO.

GF-RK 900/1800

1. DISMANTLING AN EXISTING INSTALLATION

The external antenna mount and the internal matching unit are removed

using a knife with a long, bendable blade. While bent, the knife blade is

led in between the glass surface and the unit to be removed, and with

slow, twisting movements the units can be easened off.

The external antenna mount is scrapped.

Clean the glass surface with acetone.

2. REGENERATING THE GLASSFIX® ANTENNA

Strip off the double adhesive tape remains on the matching unit. The old

tape may stick very effectively to the printed circuit board surface, and

the tape may have to be scraped off carefully with a knife.

Clean the exposed surface with acetone and mount the new double-

sided tape-pad from the “GF-RK 900/1800” kit on the unit. Align the

tape carefully while fixing it.

The antenna is now re-established and can be mounted following the normal

GlassFix® mounting procedure.

REINSTALLATION

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 by 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.
