For mobile and fixed operating configurations the antenna gain, including cable loss, must not exceed 2 dBi at
1900 MHz and 3 dBi at 850 MHz as defined in 2.1091 for satisfying RF exposure compliance. Under no condition
may an antenna gain be used that would exceed the 7W erp Part 22 and the 2W eirp Part 24 power limits.
