Supported Antennas
You can use the following antennas with the units:
Antenna	Additional information	Total gain (including cable)
BU-WH900-SMA	Whip antenna for mounting directly onto the module -	-6 dBi
	operation up to ½ mile (1 km).
BU-CFD890EL	0 dBi Dipole antenna with 15’ of Cellfoil cable and SMA connector.	0 dBi
SG900EL	5dBi Collinear omni-directional antenna with N-type connector.	5 dBi
BU-SG900-6	8dBi Collinear omni-directional antenna with N-type connector.	8 dBi
BU-YU6-900	10dBi Yagi directional antenna with N-type connector.	10 dBi
BU-YU16-900	15dBi Yagi directional antenna with N-type connector.	15 dBi
You can use the following cables with the units:
The following table shows compatible cables for different antennas when used with the BU-905U-L-T:
Antenna	North America	Australia/NZ
BU-SG900EL	Any cable.	CC10 or CC20.
BU-SG900-6	Any cable.	CC20.
BU-YU6-900	CC20.	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).
