Installing the IDU
See the installation guide for the specific IDU you are installing.
Grounding
The antenna assembly must be grounded. For grounding information, refer to your
training, best grounding practices, the Hughes Field Service Bulletin (FSB) HNS
Broadband Requirements for RG-6 and RG-11 IFL Cable Connectors, Ground Blocks
and Ground Block Location (FSB 050518_01), and applicable parts of the National
Electrical Code (NEC).
Approved cables
For a list of approved coaxial cable types for the IFL between the antenna and the
IDU, see the Hughes FSB, IFL Cable, Approved List (with lengths) for SPACEWAY
Domestic Installations (FSB 080202_01). The FSB lists the maximum cable length for
each approved cable type for all relevant radio types.
Because it is impossible to predict the requirements specific to each installation site,
you must use your own judgment and best practices to determine how to route and
connect the IFL transmit and receive cables.
