IRF2000 series – DNV GL variant
WARNING
Radio interference and possible health damage due to exceeding the permitted
transmission power!
The maximum permitted field strength can be exceeded when using directional
antennas with a high level of antenna gain.
•
Comply with the maximum permitted signal strength (EIRP) as per the
national or local regulations (see calculation example for EIRP).
•
Observe the regulations and standards which apply at the installation site of
the antennas.
•
Always have the planning, installation and acceptance of antenna systems
carried out by a specialist with electro-technical qualifications.
