Connectorized ODU antenna interfaces
The connectorized ODU also has interfaces to connect to an external antenna (Figure
1-5) via an N type connector with RF cable of type LMR100, LMR200, LMR300,
LMR400 or LMR600. The ‘V’ interface is for vertical polarization and the ‘H interface
is for horizontal polarization.

Mounting brackets
The ODU is supplied with a bracket for mounting it to a pole of 50mm (2”) to 75mm
(3”) in diameter.
The bracket allows for adjustment in both azimuth and elevation. The bracket may be
split to allow the pole mount section of the bracket to be mounted to the pole first.
This allows the installer to take the weight of the unit and secure it, one handed, with
a single mounting bolt.
Network connection
The network connection to the ODU is made via a 1000BaseT (Gigabit) Ethernet
connection. Power is provided to the ODU over the 1000BaseT Ethernet connection
using a standard IEEE 802.3at power supply.
