1 INTRODUCTION
1.1 General
This manual describes the electrical, mechanical and environmental
specifications of the FALCOM device FAL-ANT-7. This antenna is the
replacement for FAL-ANT-5 and it is recommended for use with STEPPIII devices.
FAL-ANT-7 remains the same form factor but compared to FAL-ANT 5 it has an
improved performance.
The FAL-ANT-7 represents combined active GPS and Quad Band GSM
850/900/1800/1900 MHz antenna. The unit is designed for in-vehicle (windows
plane) mounting. The antenna is delivered with 2.5 m cable set with two FAKRASMB-female connectors. The device can be connected directly to the FALCOM
STEPPIII GSM/GPS terminal, but it can be used with any other equipment that
provides the proper electrical and mechanical antenna interfaces.
The compact form-factor, the sample installation and the excellent price/
performance are making out of the FAL-ANT-7 perfect accessory for vehicle
tracking systems as well as related applications.

2 INSTALLATION INSTRUCTIONS
1. With a cleaning-cloth (not included) clean the inner side of the car
windshield, where the antenna is supposed to be installed.
2. There is a sticked adhesive pad at the bottom side of the antenna head.
Remove the protecting sheet (yellow sticker) from the adhesive pad. (On
the figure below the adhesive pad is separated, but in the delivery packing
it will be sticked at the bottom side of the antenna head).
3. Place the adhesive pad of the FAL-ANT-7 on to cleaned area of the
windshield and press the other side of the antenna head to avoid air
bubbles.
4. The FAL-ANT-7 antenna with FAKRA-SMB-female connectors has two
different colours, the blue colour has to be connected to the GPS SMBmale antenna interface of the equipment and the bordeaux colour has to
be connected to the SMB-male antenna interface of the equipment.
