DANGER indicates a potentially hazardous situation which, if not avoided, will result in death or serious injury.
WARNING indicates a potentially hazardous situation which, if not avoided, could result in death or serious injury.
CAUTION indicates a potentially hazardous situation which, if not avoided, could result in minor or moderate injury.
NOTICE is used for advisory messages concerning possible property damage, product damage or malfunction, data loss, or other unwanted results – but not personal injury.
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 possible 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.

weather conditions are either present or approaching.
a slight wind can unexpectedly create sudden strong forces on the antenna surface.
If the antenna or mount assembly begins to fall during the installation, do not attempt to catch it. Move away and let it fall.
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.

Overview
This installation guide explains how to assemble and install the Hughes AN8-074P
0.74 m Ka-band antenna. It is written for qualified installers who are familiar with satellite antenna installation practices, and are capable of properly applying the information presented.

Model AN8-074P antenna description
The Hughes model AN8-074P 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 IDU by an intra-facility link (IFL) consisting of two cables: a transmit cable and a receive cable.
Figure 1 shows the AN8-074P antenna, with radio assembly, assembled and installed on a trimast mount.

Tasks related to antenna installation
This section discusses tasks related to antenna installation and explains where to find additional information.
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 antenna 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. 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 building permit may be required before installing the antenna. It is the property owner's responsibility to obtain necessary permits and comply with local building codes.
Installing the antenna mount
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.
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.
For complete information regarding antenna mount installation, including various mounting methods, refer to:
The customer-specific installation reference sheet The HughesNet Antenna Site Preparation and Mount Installation Guide
(1035678-0001)
Refer to the installation reference sheet for any customer-specific guidelines concerning the mount installation. Use only the installation method described in the reference sheet.
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 (1035678-0001). Most installations in a commercial, industrial, or institutional environment use a non-penetrating roof mount.
Chapter 1 Overview
1037749-0001 Revision F
15
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.
Antenna parts and recommended tools

Antenna parts and recommended tools
This chapter identifies the main components and parts provided with the AN8-074P Ka-band antenna kit. It includes the following sections:
Antenna kit components Small hardware parts list on page 22 Tools on page 23
Antenna kit components
When you receive the equipment, unpack and inspect the antenna components and hardware to make sure all parts have been received in good condition.
If any parts appear to have been damaged in transit, immediately contact the freight carrier. If any parts appear to be missing or damaged, but not as a result of handling in transit, contact your dealer or distributor.
The antenna kit is shipped in two boxes; the radio assembly is shipped separately in a third box.
Note: To avoid potential damage, leave all components in their protective
packages until required.

Antenna parts and recommended tools 1037749-0001 Revision F
The main components of the antenna kit are:
Az/El mount assembly Reflector bracket and tilt plate Antenna reflector Feed support arm Radio assembly (shipped separately) Feed horn
The following sections describe and illustrate each component of the antenna kit.
Az/El mount assembly
The Az/El mount assembly, shown in Figure 2, includes components that allow you to adjust the antenna elevation and azimuththe Az/El canister, the elevation scale, and the azimuth and elevation adjustment tools.
The Az/El canister supports the antenna and secures it to the mast. The elevation scale is used to measure the angle of antenna elevation. The azimuth and elevation adjustment tools are used to finely adjust the azimuth and elevation of the reflector during antenna pointing. See the HughesNet Ka-Band Antenna Pointing Guide (1037663-0001) for detailed instructions.
