Understanding safety alert messages
Safety alert messages call attention to potential safety hazards
and tell you how to avoid them. These messages are identified by
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.
Messages concerning
property damage A NOTICE concerns property damage only.
DANGER
DANGER indicates a potentially hazardous situation 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.
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.

xii 1037312-0001 Revision B
Safety symbols The generic safety alert symbol
calls attention to a potential personal injury hazard. It appears
next to the DANGER, WARNING, and CAUTION signal words
as part of the signal word label. Other symbols may appear next
to DANGER, WARNING, or CAUTION to indicate a specific
type of hazard (for example, fire or electric shock). If other
hazard symbols are used in this document they are identified in
this section.
Additional symbols This document uses the following hazard symbols:
Indicates a safety alert message that concerns a
potential electric shock hazard.
Indicates a safety alert message concerning a
potentially hazardous situation in which you could
fall.
Indicates a safety alert message concerning a
potentially hazardous situation in which you could
be exposed to radio frequency energy.

Antenna installation
safety Observe the following precautions when installing the satellite
antenna. This guide also includes other safety alerts where
appropriate concerning specific installation procedures.
WARNING
Only Hughes-certified installers may install or service Hughes
antennas and their components. Installers must expressly
acknowledge the Hughes requirements for Hughes installations.
DANGER
If you work on a roof, tower, or other high structure or use a
ladder or scaffold to access the work site, follow these
precautions to prevent personal injury or death:
•Walk only on sound roof structures.
•Make sure the antenna assembly and installation surface
are structurally sound so that they can support all loads
(equipment weight, ice, and wind).
•Use safety equipment (for example, a lifeline) appropriate for
the work location.
•Follow all manufacturer safety precautions for all safety and
other equipment used.
•Perform as many procedures as possible on the ground.
DANGER
•To avoid electric shock, stay at least 20 ft from power lines.
•If any part of the antenna or mount assembly comes in
contact with a power line, call the local power company to
remove it.
Do not try to remove it yourself.
•For pole mount installations, be sure to obtain information
regarding underground utilities in the proposed location
before digging.
WARNING
Properly ground the antenna assembly in accordance with all
local and national electrical codes.

• Understanding safety alert messages
xiv 1037312-0001 Revision B
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, move, or mount the antenna 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.

• Understanding safety alert messages
1037312-0001 Revision B xv
CAUTION
Observe these precautions to avoid exposure to RF radiation, a
potential safety hazard:
•The antenna must be installed in a location not readily
accessible to children and in a manner that prevents human
exposure to potentially harmful levels of radiation.
•Antennas mounted in Puerto Rico, the continental United
States, or at any site with a greater than 30° elevation angle
must be installed such that the lower lip of the antenna
reflector is at least 5 ft above any surface upon which a
person might be expected to stand, and 3 ft 3 inches from
any opening (such as a door or window) in a building or
adjacent structure.
•Antennas mounted in Canada, Alaska, Hawaii, or any site
with a less than 30° elevation must be installed such that the
lower lip of the antenna reflector is at least 5 ft 9 inches
above any surface upon which a person might be expected
to stand, and 3 ft 3 inches from any opening (such as a door
or window) in a building or adjacent structure.
•The antenna must be mounted such that no object that
could reasonably be expected to support a person is within 6
ft 7 inches of the edges of a cylindrical space projecting
outward from the antenna reflector toward the satellite.
•If the above distance requirements cannot be met, the
antenna must be mounted in a controlled area inaccessible
to the general public, such as a fenced enclosure or a roof.
•A fenced installation must have a locked entry, and the
fenced area must be large enough to protect the general
public from exposure to potentially harmful levels of
radiation.
•Access to a roof installation in a commercial, industrial, or
institutional environment must be limited by a door or a
permanently fastened ladder that is locked to deny access to
the general public.
•Once the transmitter becomes operational, maintain a safe
distance; at least 3 ft.
Failure to observe these cautions could result in injury to eyes or
other personal injury.

The model AN6-098P
antenna Each remote terminal at a customer site consists of an antenna
assembly and an indoor unit (IDU). The IDU at a customer site
requires an antenna and radio assembly to communicate with the
system satellite and the Network Operations Center (NOC). The
antenna is connected to the IDU by an intra-facility link (IFL)
consisting of two cables, a transmit cable and a receive cable.
The Hughes model AN6-098P 0.98 m antenna is designed for
Ku-band applications. Figure 1 shows the antenna assembled,
with a radio assembly installed. The main parts are labeled. The
antenna shown is not yet connected, so no cables are present.

Tasksrelatedto antenna
installation This section explains where you can find information on tasks
related to antenna installation.
Selecting the
installation site Before selecting an installation site, check the installation
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 installation site.
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. Be sure to select an appropriate antenna site
before performing the installation, so that the antenna will be able
to receive the strongest signal possible.
As with any type of construction, a local building permit may be
required before installing the antenna. It is the property owner's
responsibility to obtain all permits. If necessary, adapt the
installation instructions in this guide in accordance with local
building codes.
Installing the
antenna mount Before installing the antenna, you must first install a suitable
antenna mount. Acceptable mounting methods are:
•Non-penetrating mount
•Trimast (may be used on a wood-frame roof or wood or
masonry wall)
•Pole mount
Most installations in a commercial, industrial, or institutional
environment use a non-penetrating roof 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.
For pole mounts that require a concrete base, you must allow at
least 24 hr for the concrete to cure before installing the antenna.
Be sure to plan and schedule the installation accordingly.
