External cable with loss > 9dB.

BU-YU16-900

External cable with loss > 9dB.

External cable with loss > 15 dB

You must carefully select antennas for BU-905U-L-T modules to avoid contravening the maximum power limit on the unlicensed channel. The net gain of the antenna/cable configuration should be no more than 6dB in North America (USA, Canada, Mexico) and no more than 0 dB in Australia / New Zealand.

Note: The net gain of an antenna/cable configuration is the gain of the antenna (in dBi) less the loss in the coaxial cable (in dB).
