MOUNTING THE GPRS/UMTS ANTENNA
If a SlingShot modem is used, in addition to the GPS-
antenna, two GPRS / UMTS antennas and a GPS patch
should be mounted.
The GPRS / UMTS-antennas should be mounted at
least 100 cm of each other (like the CNH antenna-
bracket in Figure 30). If a standard GPS-antenna
bracket is mounted, one of the GPRS / UMTS-antennas
should be mounted on this bracket (Figure 29). The
second GPRS / UMTS-antenna should be mounted on
a metal bracket on the cabin (Figure 31).
It is important that the following conditions are met at
all times:
The GPRS/UMTS antenna is equipped with a
magnetic base and must be placed on top of
the cabin.
The antenna should have a clear reception all
round.
Label the antenna cables inside the cabin with
labels ‘Cellular’ and ‘Diversity’ (Figure 32).
Mount a grey SMA grip on both connectors
(Figure 32).

MOUNTING GPS PATCH ANTENNA
When using a SlingShot modem also a GPS Patch
antenna should be mounted (Figure 31). The GPS
Patch antenna is magnetic. Mount the GPS Patch
antenna always on the roof of the cabin. Be careful
with mounting the GPS patch antenna; the GPS patch
antenna cable is quite thin and fragile. Label the GPS
Patch antenna cable inside the cabin with label ‘GPS’
and mount a blue SMA grip to the connector (Figure
32).
