IRF2000 series - standard
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
(e.g. the standards for antenna erection VDE 0855 and for lightning
protection VDE 0185-305).
•
Always have the planning, installation and acceptance of antenna systems
carried out by a specialist with electro-technical qualifications.
To comply with FCC / IC regulations limiting both maximum RF output power
•
and human exposure to RF radiation, the maximum antenna gain including
cable loss in a mobile-only exposure condition must not exceed:
6.5 dBi in Cellular band
3.0 dBi in PCS band
3.0 dBi in LTE Band 2
6.0 dBi in LTE Band 4
6.5 dBi in LTE Band 5
9.0 dBi in LTE Band 13
9.0 dBi in LTE Band 17
3.0 dBi in LTE Band 25
