0 Introduction
0.1 General
This manual describes the electrical, mechanical and environmental
specifications of the FALCOM device FAL-ANT-3. It contains information
about purpose and application area of the device.
The FAL-ANT-3 represents an active GPS antenna with a magnetic base
integrated inside the casing. For optional performance the antenna must be
placed on the metal surface, so that a ground plane is formed. The device is
designed for in-vehicle mounting. It is delivered with 2.5 m cable set with
SMA-male connector. The FAL-ANT-3 can be used with each type of GPS
embedded equipment that provides the proper electrical and mechanical
antenna interfaces. A range of cable adapters as an additional accessory is
provided by FALCOM too.
Users are advised to quickly proceed to the “Security” chapter and read
the hints carefully.

1 Security
This chapter contains important information for the safe and reliable use of
the GPS antenna. Please read this chapter carefully before starting to use the
GPS antenna.
1.1 General information
The Global Positioning System uses satellite navigation, an entirely new
concept in navigation. GPS has become established in many areas, for
example, in civil aviation or deep-sea shipping. It is making deep inroads in
vehicle manufacturing and before long everyone of us will use it this way or
another.
The GPS system is operated by the government of the United States of
America, which also has sole responsibility for the accuracy and
maintenance of the system. The system is constantly being improved and
may entail modifications effecting the accuracy and performance of the GPS
equipment.
1.2 Restricted use
Certain restrictions on the use of the GPS antenna may have to be observed
on board a plane, in hospitals, public places or government institutions,
laboratories etc. Follow these instructions.
1.3 Children
Do not allow children to play with the GPS antenna. It is not a toy and
children could hurt themselves or others.
1.4 Operation/antenna
Place the GPS antenna at a place where no obstruction between the antenna
and the satellite.
Make absolutely sure that the antenna socket and antenna head are correctly
installed.
Do not use a damaged antenna. Replace a damaged antenna without delay.
Technical modifications and additions may contravene local radiofrequency emission regulations or invalidate the type approval.

2 Installation instructions
Determine the mounting location for the FAL-ANT-3 antenna. The antenna
should be mounted in a horizontal or near-horizontal position. There should
be a clear horizon-round view from the mounting position, i.e. the antenna
should not be mounted in a depression or beside objects that block part of
the view. The antenna is designed for mounting on a sheet-metal structure.
The bottom side of the FAL-ANT-3 has a magnetic base, which should be
attached only to a metal sheet.
Extend the antenna cable and connect the SMA-male connector of the
antenna to the SMA-female antenna interface of the GPS receiver.
Hints
♦

♦
Proper functionality requires on-metal-mounting
Do not install the device on unmetalized parts.
To be installed inside the vehicle.
FAL-ANT-3 is not water resistant. Do not contact it to water.
