Trango Systems, Inc. GigaPlus User Manual Rev 3.1 72
Antenna Installation
Antennas are typically installed and are coarse aligned using either visually or with third
party equipment. Alternatively, some operators prefer to install the radio equipment
onto the antenna prior to installing the antenna on the rooftop or tower.
Consult the specific antenna manual for the antenna being used for detailed installation
instructions.
The Link Configuration section covers the alignment of the antennas.
Install the IDU
The IDU is supplied with mounting brackets and screws for installation into a standard
19 inch rack. The IDU is provided with a ground lug that should be connected to the rack
ground with a short length of stranded copper wire to ensure a low impedance path to
ground. When tightening screws follow the recommended torque in the Table below

A single IDU with the Rack Ears installed is shown in the Figure below. It is
recommended to always install the IDU on the left side to reduce the length of the
grounding wire to the rack.
