Hinged Right Angle 800/1900 MHz Cellular Modem Antenna ANF21HRA
Hinged Right Angle 850/900/1800/1900 MHz Cellular Modem Antenna ANQB-1HRA
43BPTCRB Requirements Note:
There cannot be any alteration to the authorized antenna system. The antenna system must be the same type with similar in-
band and out-of-band radiation patterns and maintain the same specifications.
44BFCC Requirements Note:
The antenna gain, including cable loss, must not exceed 3.0 dBi at 1900 MHz / 1.6 dBi at 850 MHz for mobile operating
configurations and 7.0 dBi at 1900 MHz / 2.3 dBi at 850 MHz for fixed mounted operations, as defined in 2.1091 and 1.1307 of
the rules for satisfying RF exposure compliance.
