8.2 GNSS Antenna for Stationary Installation

The

Multi GNSS Antenna

is an active GNSS antenna which can receive the signals of the GPS, GLONASS,

Galileo and Beidou satellite systems. It is very well suited for stationary installations, operates with a 5V DC
supply voltage provided by the receiver, and has an integrated surge protection.

The antenna cable length can be up to 70 meters if a H155 low-loss coaxial cable is used.

WARNING!

Antenna mounting without effective anti-fall protection

Danger to life due to fall!

- Pay attention to effective working safety when installing antennas!
- Never work without an effective anti-fall equipment!

WARNING!

Working on the antenna system during thunderstorms

Danger to life due to electrical shock!

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

if there is a risk of a lightning strike.

- Do not carry out any work on the antenna system if the safety distance

to free lines and sequential circuits is exceeded.
