This section explains how to install your antenna and contains the following sections:

Section Description For more information, see …

Supported antennas and cables Details the antennas and cables you can use with the units. Supported antennas on page 9.

Radio transmission distances Details the distances for reliable operation. Radio transmission distances

on page 10.

on page 11

Omni-directional antennas Details important information about using dipole and collinear Dipole and collinear antennas

antennas. on page 11.

Yagi directional antennas Details important information about using Yagi antennas. Yagi antennas on page 13.

For more information, see the next sections.

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).
