Antenna gain for M876-4
Note
Depending on the selected wireless standard and the wireless frequency used, antennas
with different antenna gains can be used. If you change the frequency band during
operation, it is possible that the maximum permitted antenna again also changes. Check
whether the antenna you are using is approved for the changed frequency range. If
necessary, change the antenna so as not to violate the operational requirements. Or use an
antenna with a gain less than 3.58 dBi to cover all bands.
