Built-in WiMAX Antenna
One high-gain internal antenna is built into the ODU for WiMAX communications.
The antenna must be aligned towards the direction of the WiMAX service provider's
base station.

Depending on a user's location, the use of an external antenna may provide a better
connection to the WiMAX base station.

using Ethernet cable. The Ethernet port connection provides power to the ODU as
well as a data link to the IDU.

A Subscriber Unit Alignment Unit (SAU) port is included for connecting an optional
SAU device that provides indicator status LEDs for antenna alignment.
