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.
