PTCRB 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.
FCC 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.
