8 Installation of the GPS Antenna

Danger of death from falling!

-  Ensure that you work safely when installing antennas!

WARNING!

Do not mount the antenna without an effective fall arrester!

Danger of death from electric shock!

WARNING!

-  Never work without an effective fall arrester!

Do not work on the antenna system during thunderstorms!

-  Do not carry out any work on the antenna system or the antenna cable
 

if there is a risk of lightning strike.

-  Do not carry out any work on the antenna system if it is not possible to maintain
    the prescribed safe distance to exposed lines and electrical substations.

Selecting the Antenna Location

To avoid difficulties with synchronization, select a location that allows for an unobstructed view of the sky
so as to ensure that enough satellites can be found. The line of sight between the antenna and satellites should
not be obstructed in any way. The antenna must also not be installed under power lines or other electrical
lighting or power circuits.

Installation Conditions for Optimum Operation:

clear view of 8

above the horizon or

clear view towards equator (if clear view of 8

not possible) or

clear view between 55th north and 55th south parallels (satellite orbits).

Note:

Problems may arise if all of these views are obstructed, as four

satellites must be located to calculate a new position.
