INTRODUCTION
This manual describes the electrical, mechanical and environmental specifications of the
FALCOM device FAL-ANT-11.
1.1 General
The FAL-ANT-11 antenna has been specifically designed for replacing the FAL-ANT-5/7
combined antennas and for the demands of today’s Telematics and AVL systems. The new
antenna comes with improved performance over existing antenna design. Combining a quadband (850/900/1800/1900MHz) cellular dipole with a high performance amplified GPS
antenna in a single, low profile windscreen mounted disc antenna. The FAL-ANT-11 is ideally
suited to the current market trend of manufacturers supplying GPS receivers with an
integrated LNA. Delivering 18dBi (nominal) at the connector, it also meets the specification of
most “high sensitivity” GPS receivers. It is supplied in black, with 2.5 metres of RG174 cable
and is terminated with FAKRA connectors.
The compact form-factor, easy installation and excellent price/performance are making out
of the FAL-ANT-11 perfect accessory for AVL or fleet management applications.

INSTALLATION INSTRUCTIONS
The FAL-ANT-11 has 2 antennas combined in a single housing - one for receiving GPS signals
and another for transmitting and receiving GSM signals. The most critical part in this antenna
is the location of GPS part as the location of the GSM part is much less critical. The FAL-ANT11 is designed for in-vehicle mouning applications. The optimal location to mount the antenna
in the vehicle is although windscreen with a clear and unobstructed view of the sky. It is not
recommended to mount the FAL-ANT-11 antenna on the windscreen in the vehicles with
heated front and steeply raked windscreens. However under a plastic dash locations are often
acceptable, but sometimes may lead to a temporally loss of GPS signals. For GSM, the most
important issue is to consider the potential interference with other in-car equipments, such as
entertainment systems. Therefore, prevent locating the FAL-ANT-11 antenna close to the
audio equipment and loudspeakers to avoid any signal interference.
Follow this procedure to mount the FAL-ANT-11 antenna:
1. Select an appropriate mounting position for the antenna (be sure that no metallic parts
are blocking the view of the sky - see more details above).
2. Peel the protective material from the supplied double-sided adhesive pad and attach it to
the antenna making sure that the satellite side of the antenna marked with the text "THIS
SIDE TO THE SKY" must face up, towards the sky when attached to the selected area.
3. Before attaching the antenna to the selected area, first test the GSM and GPS signal
strength on your PC with the help of the Workbench software to determine in which
location and in what direction you will get the best signal strength.
4. Clean the surface area of the vehicle where you will be installing the antenna with a
cleaning-cloth (not included).
5. Peel the other side of the protective material from the adhesive pad and attach the
antenna to the cleaned area and firmly press the antenna into place on the vehicle to
avoid air bubbles.
6. Double check that the location of the antenna is correct, and continue to press firmly
down on the antenna for another 20 seconds. The maximum adhesion usually occurs
within 24 hours after mounting. During this time, avoid any contact with the antenna.
7. When you have successfully mounted the antenna, route the cable from the antenna to
the connection points of your AVL device and connect the FAKRA connector bordeauxcode to the GSM antenna connector on the device and FAKRA connector blue-code to the
GPS antenna connector.
CAUTION
[1] Install the antenna inside the vehicle on the immovable windshields.
[2] Do not impair the sight of the driver !
[3] FAL-ANT-11 is non waterproof antenna. Do not contact it to water.
