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.

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.

r to the IDU in accordance with

the instructions in the IDU installation guide.

Ground connection

Ground the antenna mast at the Az/El mount by attaching the
ground wire to the elevation lockdown bolt as shown in
Figure 33. For specific grounding proc edures, refer to the sources
listed in Grounding on

Note: Although the radio transmitter contains a ground screw, a
separate ground wire to the radio assembly is not required; the
radio assembly is grounded through the metallic shield of the
coaxial cable.

This completes the installation. Yo

u must now point the antenna.

See the Ka-Band Antenna Pointing Guide (1037663-0001) for

Adjusting the antenna

azimuth and elevation

This chapter describes the process by which to adjust the antenna
azimuth and elevation to the correct position for optimum
transmission and reception. As the installer, you will perform
these procedures during the antenna pointing process. This
chapter discusses the mechanical adjustments used to modify the
position of the antenna only. It does not discuss the pointing
process itself. For information on pointing the AN8-098P and all
HughesNet Ka-Band antennas, see the HughesNet Ka-Band
Antenna Pointing Guide (1037663-0001).

Adjusting the elevation

To adjust the antenna elevation:

1. Unlock the elevation by loosening the

5/16-inch elevation
lockdown nuts on either side of the Az/El mount. Figure 34
shows the location of the nuts (only one nut is shown).

Figure 34: Elevation adjustment components

2. Loosen the top elevation adjustment

nut and spin it
counter-clockwise until it rides an inch or two up the
elevation adjustment rod.

3. Use the lower nut to adjust the elevation.

4. As shown in Figure 35, the black line on the bar behind the
lockdown nut acts as a pointer to

indicate the value in the
elevation scale. F or example, the antenna shown in the figure
is adjusted to 26°.

Adjusting the azimuth

To adjust the antenna azimuth:

1. Ensure that the three 5/16-inch azimuth lockdo

wn nuts at the
bottom of the Az/El canister (shown in Figure 36) are loose
enough that the antenna assembly rotates

freely on the mast.

2. Manually point the antenna reflector as accurately as possible
in the appropriate

direction as indicated on the installation

reference sheet.

NOTICE

Do not attempt to adjust the azimuth manually by pulling on the
antenna reflector or feed support arm. Doing so could cause
permanent damage to the antenna.

3. Tighten the three lockdown nuts just enough so th
antenna does not rotate freely.

4. Using a ½-inch wrench, rotate the azimuth adjustment bolt
shown in Figure 36 in either direction to achieve the desired
azimuth angle.

Note: Azimuth measurements are calibrated relative to true
north, not magnetic north.

5. Verify the azimuth with a compass

and tighten the three

lockdown nuts fully to secure the antenna in position.
