1. General Remarks
For optimal performance HITAG antennas have to be tuned during production, respectively by
start-up or, for service purposes, during operation. The HITAG Antenna Tuning Device is a
very easy to handle and cost effective solution for the tuning of 125 kHz HITAG antennas.
The device is - besides the HITAG antenna training - the optimal complement for antenna
design. The HT OT840 therefore is an unrenouncable tool for everybody who designs,
produces or even uses HITAG antennas.
The HITAG Antenna Tuning Device can be used for tuning HITAG long range as well as
HITAG proximity antennas.
