Understanding safety alert messages
Safety alert messages call attention to potential safety hazards and tell you how to avoid them. These messages are identif ied b y the signal words DANGER, WARNING, CAUTION, or NOTICE, as illustrated below. To avoid possible property damage, personal injury, or in some cases death, read and comply with all safety alert messages.
Messages concerning personal injury
The signal words DANGER, WARNING, and CAUTION indicate hazards that could result in personal injury or in some cases death, as explained below. Each of these signal words indicates the severity of the potential hazard.
DANGER
DANGER indicates a potentially hazardous situ ation which, if not avoided, will result in death or serious injury.
WARNING
WARNING indicates a potentially hazardous situation which, if not avoided, could result in death or serious injury.
CAUTION
CAUTION indicates a potentially hazardous situation which, if not avoided, could result in minor or moderate injury.
Messages concerning property damage
A NOTICE concerns property damage only.
NOTICE
NOTICE is used for advisory messages concerning possible property damage, product damage or malfunction, data loss, or other unwanted results—but not personal injury.

WARNING
WARNING
• Do not work in high wind or rain; or if a storm, lightning, or other adverse weather conditions are either present or approaching.
• Do not attempt to assemble , mo v e, or mount the antenn a on a windy day. Even a slight wind can unexpectedly create sudden strong forces 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 improperly installed or attached to an unstable structure are susceptible to wind damage, which can be very serious or even life threatening. The product owner and installer assume full responsibility that the installation is structurally sound to support all loads (weight, wind, and ice) and is properly sealed against leaks.

The Hughes model AN8-098P antenna is designed for Ka-band applications. Each HughesNet antenna station consists of an antenna assembly and an indoor unit (IDU), which can be either a satellite modem or a satellite router. The IDU communicates with both the HughesNet satellite and the Network Operations Control Center (NOCC) via the antenna and radio assembly.
The antenna is connected to the ID (IFL) consisting of two cables: a transmit cable and a receive cable.

T asks related to antenna installation
This section discusses tasks related to antenna installation and explains where to find additional information.
Selecting the
installation site
Installing the
antenna mount
Before selecting an installation site, check the installation reference sheet to see if a customer-specific site has been pre-determined and specifie d. 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.
The first and most important consideration when c 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.
As with any type of construction, a local b required before installing the antenna. It is the property owner's responsibility to obtain all permits. If necessary, modify the installation instructions in this manual in accordance with local building codes.
Before installing the antenna itself, 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. Have the appropriate utility company mark the location of any underground telephone wires, storm drains, etc. Also, because soils vary widely in composition and load capacity, it may be necessary to consult a local professional engineer to determine the appropriate foundation design.

lation methods documented in the
Installing the IDU
Grounding
Cabling Information
See the installation guide for the specific IDU 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 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 radios types.
Because it is impossible to predict the requirements specif each installation site, you must use your own judgement and best practices to determine how to route the IFL transmit and receive cables.
