Spring loaded latches
The ODU has four spring loaded latches. These are used to fasten the ODU to the
antenna or remote mount kit.
Waveguide polarization arrow
The waveguide polarization arrow indicates the orientation of the waveguide
interface. The arrow is parallel to the short dimension of the rectangular waveguide
aperture.
Ground connector
This is used to ground the ODU by attaching it to the mast top lightning protection
unit (LPU).
RSSI connector
The received signal strength indication (RSSI) connector is a standard BNC female
connector that provides access to an analogue voltage proportional to the received
power at the ODU input. A voltmeter is attached to the RSSI connector to measure
the voltage when aligning the antenna. For more information, see
antennas
CMU connector
This connects the ODU to the CMU. For more information, see
page 1-7.
