Function
As the antenna passes over the Transponder, it energizes the latter with an energy field
of 128 kHz. The transponder transmits its code back at half this frequency.
The relative Transponder position is measured. This relative position does not provide
the knowledge of the heading of the vehicle, as the field of the Transponder is rotation-
symmetric to the longitudinal axis of the Transponder. Via a cable with the max. length
of 20 meters (RS 422, CAN) Antenna HG 98860 is connected to the vehicle control
electronic.
