8 Mounting of the Transponder
Mounting of the Transponder
Passive UHF transponders operating at a frequency of 865–928 MHz are used for identification of vehicles
with the vehicle access control reader. To ensure a reliable identification of the transponder and to reduce
interfering environmental influences such as metal, it is recommended to mount the transponder label in the
middle of the windshield behind the interior mirror. The transponders optionally available from
FEIG ELECTRONIC GmbH are self-adhesive labels. To mount these transponders, simply remove the
protective foil on the back and attach the transponder to the windshield.
Before mounting the transponder the windshield should be thoroughly cleaned to ensure optimum adhesion
of the self-adhesive labels.
Vehicles with integrated windshield heating require special mounting of the transponder. In this case the
transponder should be mounted in an area of the windshield where no wires of the windshield heating run.
Usually corresponding information can be found in the manual of the vehicle. Otherwise, the information can
be obtained from the manufacturer.
Vehicles with tinted, vaporized or metallized windshields may occasionally experience problems identifying
the transponder. These vehicles usually also have an area in the windshield where no coating has been
applied to enable radio systems to communicate with the exterior. If possible the transponder should be
mounted at such an uncoated position. The position of the uncoated area can usually be found in the manual
of the vehicle or can be obtained from the manufacturer.
