2 antennas:
If the GSM network access is via
4G (LTE) or the auto mode, 2 anten-
nas must be used. In this case, one
antenna is connected to the main
antenna connector and the second
antenna to the diversity antenna con-
nector.

If GSM network access is via only 2G
and/or 3G, it is possible to install and
use just 1 antenna in this case. The
antenna must be connected to the main
antenna connector.
The antenna mounting bracket has different
mounting bores that permit variable and univer-
sal mounting of antennas on different types of
panel housing.
