4.4. Mounting the GPRS/UMTS antenna
If a SlingShot modem is used, in addition to the GPS-
antenna and two GPRS / UMTS antennas, a GPS patch
should be mounted.
Mount the GPRS/UMTS antennas at least 1.0 meter
from each other. The base of the GPRS/UMTS
antennas are magnetic and can be placed in
longitudinal (front/rear) or transversal direction
(left/right) on the cabin. One of the GPRS/UMTS
antenna should preferably be mounted to the GPS
antenna bracket (Figure 12). For mounting the second
GPRS/UMTS antenna an additional metal plate is
supplied in a SlingShot tractor kit (see chapter 1.2 and
Figure 15).
The base of the SlingShot GPS patch antenna is also
magnetic. Preferably mount the SlingShot GPS patch
antenna also on the universal GPS-antenna bracket
next to the GPRS/UMTS-antenna. However, another
position can be used, as long as the SlingShot GPS
patch antenna is mounted on the roof of the tractor
with a clear view.
Furthermore, it is important to meet the following
conditions at all times:
•
The GPRS/UMTS antenna is equipped with a
magnetic base and must be placed on top of the
cabin.
•
The antennas should have a clear reception all
round.
Label the GPRS/UMTS antenna cables inside the
•
cabin with labels 'Cellular' and 'Diversity' (Figure
14).
Mount a grey SMA grip on both connectors
•
(Figure 14).
