Antenna installation safety

Observe the following precautions when installing the satellite antenna. This manual also includes additional safety alerts where appropriate concerning specific installation procedures.

WARNING

Only Hughes-certified installers may install or service Hughes earth stations and 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 they can support all loads (equipment weight, ice, and wind).

• Use appropriate safety equipment (for example, a lifeline), depending on the work location.

• Follow all safety precautions from the manufacturers of all safety equipment 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 your local power company to remove it. Do not try to remove it yourself.

Failure to heed these warnings could result in serious injury or death.

• Important safety information 1037312-0001 Revision A

WARNING

• Do not work in high wind or rain or if a storm, lightning, or other adverse weather conditions are present or approaching.

• Do not attempt to assemble, move, or mount the antenna on a windy day. Even a slight wind can unexpectedly create strong, unexpected forces on the antenna surface.

• Important safety information

1037312-0001 Revision A

CAUTION

Observe these precautions to avoid exposure to RF radiation, a potential safety hazard:

• The antenna must be installed in a location or manner 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 greater than a 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

ft 3 inches from any opening (such as a door or

3 window) in a building or adjacent structure.

• Antennas mounted in Canada, Alaska, Hawaii, or any site with less than a 30° elevation must be installed such that the lower lip of the antenna reflector is at least

ft 9 inches above any surface upon which a person

5 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 which 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.

• The antenna must be mounted such that there is no object outside the controlled area which could reasonably be expected to support a person within

ft 7 inches of the edges of a cylindrical space

6 projecting outward from the antenna reflector toward the satellite.

• 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.

Failure to observe these cautions could result in injury to eyes or other personal injury.

• Important safety information 1037312-0001 Revision A

vii

CAUTION

• All installations of any type or size must carry an industry standard and government approved Radiation Hazard Caution label on the feed arm.

• A fenced or roof installation in a commercial, industrial, or institutional environment must carry a Radiation Hazard Caution sign on the access door, gate, or permanently mounted access ladder that is within plain sight of anyone approaching the antenna from the front or sides of the reflector.

Failure to observe these cautions could result in injury to eyes or other personal injury.

Some installations may require additional precautions. See also the HN System Antenna Site Preparation and Mount Installation Guide (1035678-0001).

The model AN6-098P antenna

Each remote terminal 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 remote terminal (also known as the indoor unit, or IDU) by a transmit cable and a receive cable.

The Hughes model AN6-098P .98 m Ku-band antenna is designed for both Ku-band and Ka-band applications. shows the model AN6-098P antenna, installed, with a radio assembly.

Antenna installation summary

The antenna installation steps and related tasks are summarized below. The steps in bold type are documented in this manual.

1. Choose an installation site.

2. Select a method for mounting the antenna.

3. Install the antenna mount.

Note: A critical requirement is that the mast must be plumb. The antenna assembly cannot be adjusted to correct for a mast that is not plumb.

4. Install the IDU.

Note: Install the IDU before installing the antenna so you can use the installation software to determine the pointing values (azimuth, elevation, and polarization).

5. Determine the pointing values (azimuth, elevation, and polarization) – Chapter 3

6. Install the Az/El and reflector bracket assembly on the mast – Chapter

7. Install the antenna reflector – Chapter 3

8. Install the feed rods and feed support tube – Chapter 3

9. Install the radio assembly – Chapter 4 (J-type radio) or Chapter 5 (cradle-type radio)

Note: The J-type and cradle-type radio assemblies are described in

Radio assembly types on page 15.

10. Run cables between the IDU and ODU locations.

11. Ground the antenna assembly.

Tasks related to antenna installation

This section explains where you can find information on tasks related to antenna installation.

Selecting the installation

site

Installing the antenna

mount

Factors you should consider in selecting an installation site are discussed in the HN System Antenna Site Preparation and Mount Installation Guide (1035678-0001). The installation site and mounting method may be specified in the customer-specific installation specification.

A suitable antenna mount must be installed before the antenna can be installed. Acceptable mounting methods are:

• Non-penetrating mount

• Trimast (may be used on a wood-frame roof or wood or

masonry wall)

• Pole or pedestal mount

Most installations in a commercial, industrial, or institutional environment use a non-penetrating roof mount.

For pole or pedestal mounts that require a concrete base, you must allow at least 24 hr for the concrete to cure before you can install the antenna. Plan accordingly.

For complete information concerning antenna mount installation, refer to:

• The customer-specific installation specification

• The HN System Antenna Site Preparation and Mount

Installation Guide

Installing the IDU

Chapter 1 • Overview

1037312-0001 Revision A

Grounding

The customer-specific installation specification may include customer-specific guidelines concerning mount installation. Use only the mounting method described in the specification. For mount installation instructions, see the HN Preparation and Mount Installation Guide.

See the installation manual for the IDU (also referred to as a remote terminal.)

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 50518_01C);

and applicable parts of the National Electrical Code (NEC).

System Antenna Site

Approved cables

For a list of approved cables for the interfacility link (IFL) between the antenna and the remote terminal, see the Hughes FSB, IFL Cable, Approved List (with lengths) for DW7x00,

DW60xx, and DW40xx Domestic Installations

(FSB_060316_01A). The FSB lists the maximum cable length for each approved cable type, for both 1-W and 2-W radios.

How the cable is run depends on the specific installation site. Route and connect the IFL cable according to your training and best practices.

Two antenna kits for two

radio types

You can install the .98 m antenna with either of two radio types, the J-type radio or cradle-type radio, which are described in Radio assembly types on page 15.

To support these two radio types, the antenna kit is available in two configurations, as listed in

Table 1. In this manual, the

antenna kit is used to refer to either kit.

Each antenna kit consists of two boxes of parts, as detailed in Figure 2. Most parts are common to both antenna kits. The main parts that are different in the two kits are the feed support tube, feed rods, and parts used to mount the radio assembly.

Before proceeding, refer to Table 1 and make sure you have the correct antenna kit.
