Mounting – Chapter 3

3.2 Antenna HG 98780-A

Figure 3

Mounting the antenna

The casing of the antenna has bore holes for 4 screws (also refer to Figure 4 below).
We recommend the usage of M6 hexagon socket screws. The length of the screws
depends on where the antenna is to be mounted. Please make sure that in the direc

tion of travel there is enough free space for the connections. Depending on the vari

ant up to 140 mm are needed (the picture above shows the ZA/WA variants).

Unexpected position calculations.



Observe the correct positioning and orientation of the antenna when
mounting it. The following image shows the correct positioning.
