8.2 External GPS Antenna Positioning (Optional)
TMD2 works with two types of antennas.
The technologies used are GPS, for the reception of information via
satellite, and GPRS, for data communication between the device installed
on the vehicle and the fleet manager.
The GPRS antenna is always inside the device while the GPS one can also
be external (optional).
The best place to position the GPRS antenna is on the vehicle's roof and
it can be fastened with glues, double-sided tape or with the magnet it is
provided with, by placing it on a metallic surface.
When installing the antenna, remember that the higher the position with
respect to the ground, the better the efficiency of the signal reception.
If you are installing the device inside the vehicle, the GPS antenna must
be placed where it is not covered by metallic parts or by other materials
that would screen the radio waves. Furthermore make sure you position it
with its top side up, possibly sky-facing.
If the cable provided is long enough, the best place to install the GPS
antenna is near the windshield.
The GPS antenna must be connected to the device only with the
provided connection cable.
