3.4 Connecting the GSM/GPRS and GPS Antenna
The GSM/GPRS/GPS combo Antenna is available from CES Wireless Technologies in three versions:
magnetic mount, through-hole or loose/covert. These antennas are:
 ANT-06 Magnetic mount, combo, multi band GSM/GPS antenna
 ANT-07 Through-hole/fixed mount, combo, multi band GSM/GPS antenna
 ANT-13 Loose/covert, combo, multi band GSM/GPS antenna
 ANT-19 Fixed mount, GSM only antenna
 ANT-01 Magnetic mount, GPS only antenna

ANT-02 Fixed mount, GPS only antenna
- The GSM/GPRS antenna connector on the GPS-205 is a TNC female connector. The antenna has to be
connected to the connector labeled “CELLULAR ANT”.
- The GPS antenna connector on the GPS-205 is a SMA female connector. The antenna has to be
connected to the connector labeled “GPS ANT”.
3.5 Connecting Power
The GPS-205 has an input voltage range of 9 – 30 V DC. (See Table 2 and Table 3). The power and
ignition pins can support 9 – 30 V DC input voltage. The user has an option to connect these wires
depending on the desired functionality. Described below are the desired functionality and their associated
wire connecting procedure:
GPS-205 (@ 12 Volts) Average Current (mAmps) Peak Current (mAmps)
GSM 1TX/RX 390 mA
1RX 180 mA
GSM 850/900
Idle 65 mA
0.600@32.5
GSM 1TX/RX 400 mA
1RX 190 mA
GSM1800/1900
Idle 55 mA
0.570@32.0
