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).

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

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.

J-type refers to the overall design of the radio; therefore, two radios with different model numbers may both be J-type radios.

Vertical shim kit (if required)

A vertical transmit shim kit may be required for the J-type radio assembly only. If the installation specification states that vertical transmit polarization is required, you will need to obtain and install a vertical shim kit (

Figure 11) in the radio assembly.

Otherwise, a vertical shim is not required. For more information,

Assembling the antenna

This chapter explains how to install:

• The Az/El and reflector bracket assembly – The Az/El

mount assembly and reflector bracket assembly are pre-assembled for installation as a single unit, as shown in Figure 3 on page 10.

• The antenna reflector

• The feed rods and feed support tube – The feed rods attach

to the reflector and help support the feed support tube.

Radio installation is covered in Chapter 4 for the J-type radio and Chapter 5 for the cradle-type radio.

Topics in this chapter include:

• Determining the pointing values on page 21

• General instructions for assembling the antenna on page 22

• Installing the Az/El and reflector bracket assembly on

page 23

• Attaching the reflector on page 25

• Installing the feed support tube on page 27

Determining the pointing values

CAUTION

Before you install the antenna, read all safety information in the section titled

Satellite-based commissioning (SBC) is an automated web-based method for pointing the antenna. SBC configures the IDU, calculates its exact location, and uses the location and other information to help you point the antenna. SBC calculates the values you use to set the antenna’s azimuth, elevation, and polarization, based on the information you enter and the satellite you select. It then downloads the necessary software and completes the IDU registration process.

Important safety information on page iii.

Chapter 3 • Assembling the antenna

1037312-0001 Revision A

In this manual, installation software refers to installation, pointing, and commissioning software accessed through the IDU, which works in conjunction with SBC.

Before proceeding, use the installation software to determine the initial values to use for setting azimuth, elevation, and polarization. Record these values and keep them handy for reference as you install and point the antenna. To use the installation software, follow the instructions in the IDU installation manual for commissioning the IDU.

General instructions for assembling the antenna

Before you assemble the antenna, read these important instructions:

• Mast – The mast must be installed before you can install the antenna. For information on antenna mounting methods, see

the HN System Antenna Site Preparation and Mount Installation Guide (1035678-0001). The mast must have an

outside diameter of 2-

⁄8 inches (2.375 inches).

• Sequence of steps – When you assemble the antenna, follow

the instructions in this chapter in the order they are presented.

• Tightening hardware– Do not tighten any nuts or other hardware until you are instructed to do so. (See also the next

item, Torque.)

• Torque – To ensure successful installation of the antenna, you must tighten all nuts and socket-head cap screws to the maximum torque values shown in

Tabl e 6. This is a critical

requirement.

Chapter 3 • Assembling the antenna 1037312-0001 Revision A

For bolts that use a split lock washer, tighten the bolt until the washer is flattened, but do not tighten the bolt further. When the washer is flattened, this indicates that sufficient torque has been applied.

Installing the Az/El and reflector bracket assembly

Bubble must be centered between marks.

Follow these steps to install the Az/El and reflector bracket assembly onto the mast:

1. Before you install the Az/El and reflector bracket assembly onto the mast pipe, use a bubble level to make sure the mast is plumb.

Check the mast at two perpendicular locations, as shown in Figure 14.

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

To make sure the mast is plumb, check with the level in two positions at right angles to each other.

3. Optional: If you adjust the antenna elevation now to the coarse elevation value, before installing the reflector, it’s easier than making this adjustment after the reflector is attached. You can make this adjustment now or do it as part of the antenna pointing procedure. (See

Setting coarse

elevation on page 61.)

4. Rotate the Az/El and reflector bracket assembly until the reflector side is oriented in the general direction of the satellite.

If necessary, loosen the canister nuts just enough to allow the assembly to rotate.

5. Snug the three canister nuts just enough to prevent the assembly from rotating. Do not tighten the nuts at this time.

Chapter 3 • Assembling the antenna 1037312-0001 Revision A

Attaching the reflector

Follow these instructions to attach the antenna reflector to the reflector bracket.

Note: This task is easier if someone assists you.

1. Orient the reflector so the HughesNet logo on the front is near the top, as shown in

Figure 16.

2. Lift the reflector and align the four mounting holes on the back of the reflector with the four mounting holes on the reflector bracket. See

Note: To make it easier to position the reflector and insert the screws (steps Az/El and reflector bracket assembly beyond the 80° mark on the elevation scale so the surface of the reflector bracket that attaches to the reflector is nearly horizontal. Then you can lay the reflector on the bracket, with the holes in the reflector facing the bracket. This method (not illustrated here) is especially useful when one person installs the antenna.

To use this method you must loosen the fine elevation adjustment nuts and elevation lockdown bolts identified in Figure 48 on page 60. Be sure to tighten the elevation lockdown bolts before laying the reflector on the bracket.

Chapter 3 • Assembling the antenna 1037312-0001 Revision A

Installing the feed support tube

Install the feed rods and feed support tube as explained in the following two sections. These instructions apply to both types of feed support tubes and feed rods, that is, the tube and feed rods for the J-type radio or cradle-type radio.

Note: If you are installing an antenna that will use a cradle-type radio assembly, make sure the feed support tube and feed rods are stamped TG. (Other letters or numbers may appear with TG.) If these parts are not stamped TG, they are the wrong parts for the cradle-type radio. Contact Installer Support to obtain the correct parts.

Attaching the feed rods

Attach the feed rods to the reflector:

1. Attach the feed rods to the rim of the reflector as shown in Figure 18. The feed rod end with the longer flat part attaches to the reflector rim; the end with the shorter flat part attaches to the feed support tube (as shown in

Figure 19 on page 28).

Point the lower end of each feed rod inward, toward the space in front of the lower part of the reflector. When both feed rods are correctly installed, their lower ends are just a few inches apart.

Installing a shim for vertical transmit polarization

Follow the instructions in this section only if the installation specification or service order states that vertical transmit polarization is required. (The vertical shim kit is not used with

the cradle-type radio.)

If vertical transmit polarization is not required, go to Installing the radio assembly on page 36.

The radio assembly is shipped with a horizontal transmit polarization shim installed. If vertical transmit polarization is required, you must remove the horizontal shim and replace it with a vertical transmit polarization shim.

Note: If you need to change from horizontal to vertical transmit polarization on an antenna that has the radio assembly already installed on the feed support tube, you will have to remove the radio assembly from the feed support tube before you can follow the instructions in this section.

Figure 23 shows where the shim is located and shows three of the four Allen screws that hold the shim in place.

To replace the horizontal shim with a vertical shim, follow these steps:

1. Obtain a vertical transmit polarization shim kit (Hughes model VTX-SHIM-KIT, P/N 1033809-0001). Figure 24 on page 33 shows what a vertical shim looks like.

2. Loosen and remove the four Allen screws that hold the shim in place. See

Figure 23.

3. Separate the end of the waveguide from the shim.

5. Install the vertical shim and O-ring in the same location. Because of its shape and alignment pins on the transmit/receive isolation assembly (TRIA), the vertical shim can only be installed in the position shown in

Figure 24 (upper right photo). Note the position of the alignment pins. Likewise, the horizontal shim can only be installed in one position.

Because of the shim’s alignment pins, you must rotate the TRIA 90

° from its horizontal polarization position. You must rotate the TRIA before you re-attach the waveguide end so you can insert the shim alignment pins into the waveguide end plate. See Figures

25 and 26.

To calculate the polarization setting, refer to the section for the type of uplink and downlink that will be used. In these instructions, SBC initial value refers to the polarization value calculated by the installation software.

To calculate the radio polarization setting for a horizontal

/ vertical downlink:

uplink

1. Multiply the SBC initial value by –1, then offset the result by 90° as follows: If the SBC initial value is positive, add 90. If the SBC initial value is negative, subtract 90.

Example 1, positive initial value of 41°

41 × –1 = –41 Add 90: –41 + 90 = 49 Radio polarization setting = 49°

Example 2, negative initial value of –41°

–41 × –1 = 41 Subtract 90: 41 – 90 = –49 Radio polarization setting = –49°.

For a vertical uplink /

horizontal downlink

2. Make a note of the setting.

3. Go to Setting the radio polarization on page 48.

To calculate the radio polarization setting for a vertical uplink

Cabling and connections

This chapter illustrates where the ODU ground, transmit, and receive connectors are located; shows how to route the transmit and receive cables at the ODU; and explains how to connect the transmit and receive cables to the radio assembly. You must connect the transmit, receive, and ground cables before you can point the antenna (

The chapter includes these sections:

• Previous cabling work on page 49

• Routing the cables at the ODU on page 50

• Ground connection on page 51

• Connecting the transmit and receive cables on page 52

Chapter 7 – Pointing the antenna).

Previous cabling work

Before you can complete the steps explained in this chapter, you must route and terminate the transmit and receive cables from the IDU to the ODU.

For a list of approved cables for the IFL between the antenna and the remote terminal, see the Field Service Bulletin (FSB), IFL

Cable, Approved List (with lengths) for DW7x00, DW60xx, and DW40xx Domestic Installations (FSB_060316_01A). This FSB

lists the maximum cable length for each approved cable type, for both 1-W and 2-W radios.

How the cables are run depends on the specific installation site. Route and connect the cables according to your training and best practices.

CAUTION

Coaxial connectors and cable can corrode if exposed to moisture. Use only compression type connectors, and weatherproof them with dielectric grease and weatherproof tape.

As you perform these procedures, observe the following safety precautions:

• This device emits radio frequency energy when in transmit mode. To avoid injury, do not place head or other body parts between feed horn and antenna when system is operational. Keep at least 2 ft away from the area between the feed horn and the reflector when the system is operational.

• Make sure the cylindrical space projecting outward from the antenna reflector toward the satellite does not intersect or come close to any inhabited areas.

• Disconnect power from the IDU before performing maintenance or adding upgrades to any antenna components.

1037312-0001 Revision A

Antenna pointing overview

This chapter describes a general procedure for pointing the antenna. The objectives of antenna pointing are to:

• Locate and detect the satellite signal

• Peak the signal to achieve the greatest possible signal

strength

Using the installation

software

Peaking the signal

(description)

The IDU installation software guides you through a step-by-step process for installing the IDU and pointing the antenna. It calculates your exact location and the values you use to set elevation, polarization, and azimuth. (See also pointing values on page 21.)

Use the information in this chapter as a guide for the overall pointing process and for instructions on how to make mechanical adjustments to the antenna. For specific steps, follow the instructions in the IDU installation guide and on the installation software screens.

In general you will alternate between these two activities:

• Following the software prompts and instructions

• Adjusting the antenna (elevation, polarization, and azimuth)

to acquire and then peak the satellite signal. The required adjustments are different for each installation location.

Correct antenna alignment is critical to the operation of the system. When the antenna is pointed directly at the satellite, it receives a strong signal. If it is not pointed properly, the signal may be weak, and errors may result during data transfers.

Antenna pointing is accomplished by first receive pointing the antenna and then isolating the transmit signal. Receive pointing adjusts the antenna to obtain the best receive signal. Isolating the transmit signal fine tunes the antenna alignment for the strongest possible signal received by the HN are explained later in this chapter.

System NOC. Both processes

Determining the

Chapter 7 • Pointing the antenna 1037312-0001 Revision A

To point the antenna, you go through cycles of making small adjustments to the antenna until you are satisfied you cannot get a stronger satellite signal. When you have achieved the strongest possible signal, you have peaked the signal.

You may achieve the strongest signal strength after just a few adjustments, or you may find that several adjustments are needed. By obtaining the strongest possible signal you ensure that the terminal can operate with peak performance.

Personnel requirements

One person can point the antenna if an outdoor pointing interface (OPI) is used. Otherwise, pointing is usually a two-person task. If an OPI is not used, one person aims and adjusts the antenna while the other watches the signal strength display on a computer and relays the readings to the person at the antenna. A portable telephone or walkie-talkie is helpful for this.

Pointing parameters

Prerequisites for antenna pointing

Outdoor pointing interface

Prior to antenna pointing, you use the installation software to enter parameters such as longitude, latitude, and polarization angle. Or you can enter the local ZIP code and let the software calculate these values.

The following are required for antenna pointing:

• The antenna must be installed.

• The IDU must be installed.

• The transmit and receive cables must be connected to the

IDU and ODU.

• The OPI, if used, must be installed. (See Installing the OPI on page 58.)

• The ODU and IDU must be grounded.

• You must have access to the installation software through the

IDU.

The OPI (Hughes P/N 1031393-0002), shown in Figure 45, is an optional tool that displays signal strength values.

Adjusting the antenna

Note: When recording or using antenna pointing

values, you must pay attention to whether values are positive (+) or negative (-).

Elevation

To point the antenna you make three adjustments to the position of the antenna reflector:

• Elevation – Adjustment up and down

• Polarization – Rotational adjustment

• Azimuth – Side-to-side adjustment

These adjustments are illustrated in Figure 47. The corresponding mechanical adjustments on the antenna are shown in Figure 48.

Chapter 7 • Pointing the antenna 1037312-0001 Revision A

Setting coarse elevation

The antenna pointing procedure begins with the steps described in this section and continues through the end of this chapter. Follow the instructions in the order they are presented.

Set the initial (coarse) antenna elevation to the initial elevation value given by the installation software, as follows:

1. Loosen the two fine elevation adjustment nuts indicated in Figure 49 so the antenna reflector can move forward and backward.

2. Loosen the two elevation lockdown bolts indicated in Figure 49, a little at a time, until you can rotate the antenna reflector forward and backward to adjust the elevation.

Note: Do not tighten the elevation lockdown bolts yet because you will be adjusting elevation further, as explained

Fine elevation adjustment on page 62.

3. Set the elevation to the value given by the installation software.

Fine elevation adjustment

The fine elevation adjustment rod (shown in Figure 50) allows you to make fine adjustments of the antenna elevation. Where subsequent instructions call for fine adjustment of the antenna elevation, fine-tune the elevation setting as follows:

1. Make sure the two elevation lockdown bolts are loose enough to allow the reflector to move as indicated by the arrow in Figure 50.

2. While watching the signal strength display, adjust the fine elevation adjustment nuts ( signal strength:

a. Move the top nut to allow movement, then make

adjustments with the bottom nut.

b. Adjust by turning the bottom nut a few turns clockwise and

counterclockwise, until you peak the signal.

3. When the signal is peaked, tighten the two elevation lockdown bolts.

Receive pointing peaks the receive signal. You must peak the signal even if the antenna is locked to it.

You use the installation software to check the signal strength. Then you adjust the antenna to peak the signal. The installation software shows numerical and graphic indications of signal strength. Detailed instructions for these procedures are given in the following sections.

Initial elevation setting

Make sure the antenna reflector is set to the initial elevation value given by the installation software.

Setting polarization

Polarization refers to rotation of the antenna (as shown in Figure 47 on page 59) and is measured in degrees from zero (no rotation), positive or negative. Polarization is positive east of the satellite longitude and negative west of the satellite longitude.

For an antenna with a J-type radio, you adjust polarization on the antenna only. For an antenna with a cradle-type radio, you set polarization on the antenna to 0° and then set polarization on the radio. If you are installing the antenna with a cradle-type radio,

Setting polarization for the cradle-type radio on page 47.

see (You will also use the instructions in this section.)

Set the antenna (reflector) polarization as follows:

1. Loosen the four polarization lockdown nuts just enough so you can rotate the antenna reflector. See

Figure 51. Do not adjust the center nut on each side, as noted in Figure 51.

2. Rotate the antenna to the desired polarization value as indicated by the polarization scale (shown in

Figure 51).

J-type radio: Set the antenna polarization to the initial polarization value given by the installation software.

Cradle-type radio: Set the antenna polarization to 0° ; then

Setting azimuth

With the elevation and polarization set to the initial values given by the installation software, follow these steps to set the antenna azimuth to the initial value specified by the installation software and then adjust it as necessary:

1. Use a compass to determine the azimuth bearing specified by the installation software.

2. Prepare to make azimuth adjustments as follows: a. Fully loosen the three canister nuts shown in Figure 52. b. Tighten the top nut only, just enough so you cannot rotate

the Az/El assembly around the mast.

c. Loosen the top nut incrementally until you can rotate the

Az/El assembly by holding and moving it.

Canister

Loosen these three nuts to rotate Az/El assembly and reflector from side to side.

View from behind reflector

3. Stand behind the antenna, grasp the antenna reflector bracket (not the reflector), and rotate the antenna assembly about the mast until the reflector is pointed in the approximate azimuth heading.

4. Adjust the azimuth to the right about

⁄8 inch.

5. Let go of the reflector bracket and count slowly to 5 while reading the signal strength value from the OPI or computer.

You must allow the IDU enough time to track and register the signal strength.

Note: Make small adjustments (not more than azimuth as measured at the mast). Wait 5 sec between adjustments to give the IDU enough time to lock onto the satellite signal.

⁄8 inch of

6. After acquiring a signal, adjust the azimuth to obtain the highest signal quality.

7. Go to Peaking the signal (procedure) on page 66 and follow the instructions there.

If you cannot detect a signal Follow the steps in this section (steps 1 through 3 and/or steps 1

through 6) only if you cannot detect a signal.

If no signal is present:

1. Repeat steps 3 through 5 in Setting azimuth on page 64. (Adjust the reflector to about

⁄8 inch to the right of the

approximate azimuth.)

2. Keep moving the antenna reflector to the right a little at a time until you detect a signal.

3. If there is no signal, sweep back

⁄8 inch at a time to the left

until you detect a signal.

If you still cannot detect a signal, there may be an error. If there is no signal, perform the following quick checks.

1. Check the coaxial cable connections at the LNB, IDU, and all the connections in between.

2. Make sure there are no obstructions such as trees blocking the signal.

3. Make sure you recorded and properly set the azimuth, elevation, and polarization values.

4. Verify the azimuth setting by moving 15 ft in front of or behind the antenna and taking another compass reading. Metal near the compass, such as a car or even a belt buckle, can give a false reading.

5. Point the front of the antenna reflector to the left of the estimated bearing.

6. Go back to step 3 in Setting azimuth on page 64 and try again.

When you have acquired a signal and adjusted azimuth to obtain the highest signal quality, go to

Peaking the signal (procedure) on

page 66 and follow the instructions there.

Chapter 7 • Pointing the antenna

1037312-0001 Revision A

Peaking the signal

(procedure)

After the satellite signal is detected, peak the signal as follows:

1. Mark the mast with a pencil so you can find the azimuth bearing again.

2. After detecting the satellite, continue turning the antenna reflector a small amount in the same direction you were turning it when you began receiving the satellite signal.

Pause for 5 sec after each time you move the reflector.

3. Turn the reflector in this fashion until the signal strength values displayed by the installation software begin to decrease.

4. When the numbers begin to decrease, slowly turn the reflector in the opposite direction until you regain the highest number that was previously achieved.

(Achieving this maximum signal strength is called peaking the signal.)

Make a note of the peaked signal strength for reference as you complete the pointing process.

5. When you have peaked the azimuth, snug down the three canister nuts as follows: a. Alternately and incrementally tighten the lower two nuts

until the flanges makes contact.

b. Snug the top nut.

6. Fine tune the elevation adjustment to verify that signal strength remains at the highest level.

7. If necessary, fine tune the adjustments for azimuth, elevation, and polarization to make sure you have achieved and maintained the highest possible signal strength.

8. Erase all marks previously made on the mast.

9. Lock down (fully tighten) all adjustment nuts.

Chapter 7 • Pointing the antenna 1037312-0001 Revision A

Isolating the transmit signal

To prevent signal cross talk, you use a procedure known as Automated Cross Polarization (ACP) to isolate the transmit signal from the receive signal. ACP test functions are included in the installation software.

The ACP software operates in two different modes—manual or automatic. Manual mode gives real-time feedback of cross polarization isolation measurements while you adjust the antenna. Automatic mode takes a snapshot of the cross polarization isolation measurement.

ACP fine pointing consists of testing using both the manual and automatic modes and adjusting the antenna by small increments (if necessary) until it passes both the manual and automatic ACP tests.

Follow the general instructions below for the ACP tests. Use the installation software screens to initiate tests and see the test results.

Manual ACP test

First run a manual ACP test:

1. Lock down all antenna adjustment nuts and bolts.

2. Initiate the manual ACP test by selecting the manual cross polarization test type.

If the manual ACP test passes, stop the test and proceed to Automatic ACP test on page 68.

If the manual ACP test fails, let the test continue and follow these

steps:

1. Make small, 1 ° or less changes in polarization while observing the transmitter isolation.

2. Peak the polarization to the highest possible transmitter isolation.

3. Tighten the polarization lockdown nuts.

4. Check the signal strength.

When the manual ACP test passes, stop the test and proceed to Automatic ACP test.

Chapter 7 • Pointing the antenna

1037312-0001 Revision A

Automatic ACP test

Verify that the signal is still peaked by initiating an automatic ACP test. To initiate this test, select the automatic cross polarization test type. If the antenna passes the automatic ACP test and maintains signal strength within 3 strength scale, it is pointed and ready to be registered.

If the antenna fails the automatic ACP test, follow these steps:

1. Initiate a manual ACP test.

2. When the test starts, make small, 1 ° or less changes in polarization while observing the transmitter isolation.

3. Peak the polarization to the highest possible transmitter isolation.

4. Tighten the polarization lockdown nuts.

5. If the antenna passes the manual test, stop the manual test and run the automatic ACP test again.

6. Check the signal strength.

If the antenna passes the automatic ACP test and maintains signal strength within 3 and ready to be registered.

If the antenna passes the automatic ACP test, but the signal strength drops more than 3 points after the test, you must repeat

the fine adjustments for azimuth and elevation:

points on the signal strength scale, it is pointed

points on the signal

1. Repeat the fine adjustments for both azimuth and elevation to maximize the signal strength.

2. Repeat the automatic ACP test.

3. Check the signal strength.

If the antenna passes the automatic ACP test and maintains signal strength within 3 and ready to be registered.

If the antenna still does not meet both criteria, repeat very small polarization, azimuth, and elevation adjustments and ACP tests as many times as necessary until you have peaked the signal and the antenna passes the automatic ACP test and signal strength is maintained within 3

Important: When you are finished pointing the antenna, lock down all pointing adjustments. All adjustment points are shown in

Figure 48 on page 60.

Final steps

Complete the following steps before leaving the installation site.

Remove the OPI

Check for safety labels and

signs

Subsequent steps

Remove the OPI so you can re-use it for subsequent installations:

1. Disconnect the OPI and block, if used.

2. Reconnect the receive cable to the radio.

Make sure the required safety labels and/or signs are present:

• Make sure a Radiation Hazard Caution label is present, legible, and visible on the feed arm and on the back of the antenna reflector.

• If the antenna is enclosed by a fence, make sure a Radiation Hazard Caution sign is present, legible, and visible on the

entrance gate.

• If the antenna is installed on a roof with a permanently mounted access ladder, make sure a Radiation Hazard Caution sign is present, legible, and visible on or near the ladder.

The antenna is now installed and pointed, ready for operation.

To commission the IDU (remote terminal), refer to the IDU installation manual.
