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

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

2 Installation instructions<br />
Determine the mounting location for the <strong>FAL</strong>-<strong>ANT</strong>-3 antenna. The antenna<br />
should be mounted in a horizontal or near-horizontal position. There should<br />
be a clear horizon-round view from the mounting position, i.e. the antenna<br />
should not be mounted in a depression or beside objects that block part of<br />
the view. The antenna is designed for mounting on a sheet-metal structure.<br />
The bottom side of the <strong>FAL</strong>-<strong>ANT</strong>-3 has a magnetic base, which should be<br />
attached only to a metal sheet.<br />
Extend the antenna cable and connect the SMA-male connector of the<br />
antenna to the SMA-female antenna interface of the GPS receiver.<br />
Hints<br />
♦<br />
♦<br />
♦<br />
♦<br />
Proper functionality requires on-metal-mounting<br />
Do not install the device on unmetalized parts.<br />
To be installed inside the vehicle.<br />
<strong>FAL</strong>-<strong>ANT</strong>-3 is not water resistant. Do not contact it to water.<br />
