Where is the OBU installed?

[StKai]

Best installation locations are as follows: 1. Height should be no less than 1.2 meters and no more than 2.5 meters. 2. Installation angle N should be between 30-90 degrees (the angle between the electronic tag surface and the horizontal plane). 3. For small vehicles such as cars and minivans, the OBU device should be installed in the upper middle part of the front windshield. For large vehicles like trucks and buses, the installation position should be in the middle lower part. 4. If the vehicle has anti-explosion film or is fitted with anti-explosion film later, since the film contains metal ions that may affect microwave communication signal transmission, it should be installed in the "microwave window" area or a rectangular area of 8cmX10cm should be cut out from the anti-explosion film.
