IRF1000 series
WARNING
Radio interference and possible damage to health 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.
Per the requirements of the U.S. Federal Communications Commission
•
(FCC) and the Canadian ISED (Industry Canada), the antenna gain
(including power losses) must not exceed the following values when
operating in North America:
LTE
Band 2 (1850–1910 MHz)
Band 4 (1710–1755 MHz)
Band 5 (824–849 MHz)
Band 7 (2500–2570 MHz)
Band 12 (699–716 MHz)
Band 13 (777–787 MHz)
Band 25 (1850–1915 MHz) 6 dBi
Band 26 (814–849 MHz)
Band 30 (2305–2315 MHz) 1 dBi (external vehicle antennas not permitted!)
Band 41 (2496–2690 MHz) 9 dBi
UMTS
Band 2 (1850–1910 MHz)
Band 4 (1710–1755 MHz)
Band 5 (824–849 MHz)
