Antenna installation safety
Observe the following precautions when installing the antenna. This manual also includes other safety alerts where appropriate concerning specific installation procedures.
WARNING
Only Hughes-certified installers may install o r service Hughes antennas and their components. Installers must expressly acknowledge the Hughes requirements for Hughes installations.
DANGER

WARNING
• Do not work in high wind or ra in; or if a st orm, lightning, or other adverse weather condit ions are either present or approaching.
• Do not attempt to assemble, move, or mount the antenna on a windy day. Even a slight wind can unexpectedly creat e sudden strong f orces on the antenna surface.
CAUTION
If the antenna or mount assembly begins to fall during the installation, do not attempt to catch it. Move away and let it fall.
WARNING
Antennas that have been impr oper ly insta lled or attac hed to an unstable structure are suscepti ble to wind damage, which can be very serious or even life threatening.

Each satellite modem at a customer site requires an antenna and radio assembly to communicate with both the system satellite and the Network Operations Control Center (NOCC). The antenna is connected to the satellite modem by an intra-facility link (IFL) consisting of two cables: a transmit cable and a receive cable.
The Hughes model AN8-098R antenna is designed for Ka-band applications. Figure 1 shows the AN8-098R assembled, with a radio assembly.

T asks related to antenna installation
This section explains where to find information on tasks related to antenna installation.
Selecting the
installation site
Installing the
antenna mount
The first and most important consideration when choosing a prospective antenna site is whether the area can provide an acceptable line of sight (LOS) to the satellite. A site with a clear, unobstructed view of the southern sky is necessary. Also, consider obstructions that may occur in the future, such as the growth of trees. Select your antenna site before performing the installation, so that the antenna will be able to receive the strongest signal available.
Before selecting an installation site, check the reference sheet to see if a customer-specific installation site has been pre-determined and specified. Also, refer to the HughesNet
Antenna Site Preparation and Mount Installation Guide
(1035678-0001), which discusses the factors that you should consider when selecting an antenna installation site.
As with any type of construction, a required before installing the antenna. It is the property owner's responsibility to obtain all permits. Install the antenna in accordance with local building codes.
Before installing the antenna, you must first install a suitable antenna mount. If the system requires a pole mount installation, be sure to obtain information about the underground utilities in the proposed location. Hav e the appropriate utility compan y mark the location of any underground telephone wires, storm drains, etc. Also, because soils vary widely in composition and load capacity, it may be neces sary to consult a local professional engineer to determine the appropriate foundation design.

least Be sure to plan and schedule the installation accordingly.
For complete information regarding antenna mount instal including various mounting methods, refer to:
• The

Refer to the installation reference guidelines concerning the mount installation. Use only the installation method described in the reference sheet.
sheet for any customer-specific
lation,
If the installation reference sheet does not specify a method, use only the mount installation methods documented in the HughesNet Antenna Site Preparation and Mount Installation Guide. Most installations in a commercial, industrial, or institutional environment use a non-penetrating roof mount.
Installing the
satellite modem
Grounding
Approved cables
See the installation guide for the specific satellite modem you are installing.
The entire 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).
For a list of approved cables for the IFL between the antenna and the satellite modem, see the Hughes FSB, IFL Cable, Appro ved List (with lengths) for SPACEWAY Domestic Installations (FSB 080111_01). The FSB lists the maximum cable length for
approved cable type for all relevant radio types.
