It is recommended to mount the antenna at the side of the roadway on a mast. The mounting height depends
on the type of vehicle that should be detected.
Vehicle Type
Recommended Mounting Height
cars only
approx. 2.0 m
lorries and busses only
approx. 2.5 m
cars, lorries & busses
approx. 2.0 m
Table 12: Recommended mounting height depending on vehicle type
The antenna should be mounted at an angle of approx. 45° to the roadway.
If the vehicle access control reader is used to control a barrier, the antenna should be mounted at a sufficient
distance in front of the barrier. The distance depends on the permitted or desired speed of the vehicles. In
this way, it is possible for the individual vehicles to access the respective area smoothly and without delay.
In case an access from two different directions is possible, or in case of difficult environmental conditions at
the point of installation, a second additional antenna can be installed and connected to the reader.
