Installing GSM/GPRS Antenna
To install the GSM/GPRS modem, you need to mount the antenna to the
mast and insert the SIM card into the modem (see section Preparing
GSM/GPRS Modem on page 94).
The GSM/GPRS antenna is an omnidirectional antenna. The antenna
provides high gain, enabling better signal at installation sites where long
distances to the base station or the terrain cause uncertain connections. In
addition to giving a stable connection, a strong signal also reduces the
power consumption of the station. The antenna cable is high-quality
coaxial cable.
1. Install the GSM/GPRS antenna to the mast at the height of
approximately 5 meters. Check that the antenna cable reaches its
connector well and that there is some loose cable.
2. Bind the cables to the mast with cable ties.
3. Connect the antenna cable to the GSM Antenna connector on the
bottom of the enclosure; see section Connecting Sensor Cables on
page 95.
