1. Introduction
WARNING: RF Radiation Hazard -This stabilized antenna system is designed to be used with
transmit/receive equipment manufactured by others. Refer to the documentation supplied by the
manufacturer which will describe potential hazards, including exposure to RF radiation, associated with
the improper use of the transmit/receive equipment. Note that the transmit/receive equipment will
operate independently of the stabilized antenna system.
The ultimate responsibility for safety rests with the facility operator and the individuals who
work on the system.
1.1. General System Description
Your system includes a fully stabilized antenna that has been designed and manufactured so as to be inherently
reliable, easy to maintain, and simple to operate. The equipment essentially permits unattended operation except for
start-ups or when changing to different transponders, or satellites.
1.2. Purpose
This shipboard Transmit-Receive (TXRX) system provides you with two-way satellite voice/data broadband
communications while underway on an ocean-going vessel. This can be used to provide a wide variety of telephone,
fax and high speed data applications. Your antenna system can transmit to and receive from any desired Ku-band
satellite which has adequate signal coverage in your current geographic area. This input will be distributed to your
satellite modem and then to all of your other below decks computer, fax and telephone equipment.
1.3. System Components
Your Series 09 TXRX system consists of two major groups of equipment; an above-decks group and a below-decks
group. Each group is comprised of, but is not limited to, the items listed below. All equipment comprising the Above
Decks is incorporated inside the radome assembly and is integrated into a single operational entity. For inputs, this
system requires only an unobstructed line-of-sight view to the satellite, Gyro Compass input and AC electrical power.
For more information about these components, refer to the Basic System Information section of this manual.
A. Above-Decks Equipment (ADE) Group
1. Stabilized antenna pedestal
2. Antenna Reflector
3. Feed Assembly with LNB(s)

1.4. General scope of this manual
This manual describes the Sea Tel Series 09 Antenna (also called the Above Decks Equipment), its’ operation and
installation. Refer to the manual provided with your Antenna Control Unit for its’ installation and operating
instructions.
1.5. Quick Overview of contents
The information in this manual is organized into chapters. Operation, basic system information, installation, setup,
functional testing, maintenance, specifications and drawings relating to this Antenna are all contained in this manual
PRELIMINARY

Operation 6009-33 Broadband At Sea
2-1
2. Operation
Operation of your system is accomplished from the DAC-2202 Antenna Control Unit (ACU). Refer to the operation section of
the DAC-2202 Antenna Control Unit manual.
2.1. System Power-up
Turn the Power switch on rear panel of the Antenna Control Unit (ACU) ON.
2.2. Antenna Initialization
A functional operation check can be made on the antenna stabilization system by observing its behavior during the 3
phases of initialization.
Turn the pedestal power supply ON. This will release the elevation and cross-level bakes and the PCU will initialize the
stabilized portion of the mass in the following phases:
1. Elevation axis activates - Input from the LV axis sensors are used to drive the Elevation of the equipment
frame and dish to an elevation angle of 45.0 degrees.
2. Cross-Level axis activates - Input from the CL axis sensors are used to drive cross-level of the equipment
frame to bring the cross-level beam to level.
3. Azimuth axis activates -Antenna drives clockwise in azimuth until the “Home Flag” signal is produced. This
signal is produced when the home switch sensor is in close proximity to the metal home tab mounted under
the power ring. An yellow LED in the back of the home switch sensor flashes when the metal home tab is first
sensed.
This completes the phases of initialization. At this time the antenna elevation should 45.0 degrees and Relative
azimuth should be at home flag (typically this is in-line with the bow of the ship). The PCU will keep the antenna
actively stabilized at its current azimuth and elevation pointing angle
If any of these steps fail, or the Antenna Control Unit reports model number as "xx09" re-configure the PCU as
described in section the Setup section of this manual. If initialization still fails, refer to the troubleshooting section of
this manual.
2.3. Antenna Stabilization
After initialization has completed, real-time stabilization of the antenna is an automatic function of the PCU.
2.4. Stabilized Pedestal Assembly Operation
Operation of the stabilized antenna Pedestal Control Unit (PCU) is accomplished remotely by the Antenna Control Unit
(ACU). Refer to the Operation section of the Antenna Control Unit manual for more specific operation details. There
are no other operating instructions applicable to the pedestal assembly by itself.
2.5. Tracking Operation
Tracking optimizes the antenna pointing, in very fine step increments, to maximize the level of the satellite signal
being received. The mode of tracking used in this antenna is a variation of Conical Scanning called DishScan. Tracking
is controlled by the ACU. You can toggle Tracking ON/OFF from the ACU.
DishScan continuously drives the antenna in a very small circular pattern at 60 RPM. The ACU evaluates the received
signal throughout each rotation to determine where the strongest signal level is (Up, Right, Down or Left) and then
issues the appropriate Azimuth and/or Elevation steps to move the antenna toward where stronger signal is.
The pedestal cannot control tracking. Refer to the ACU manual for more Tracking information.
2.6. Antenna Polarization Operation
Linear feeds are equipped with a polarization motor and potentiometer feedback and are controlled from the Antenna
Control Unit. Circular feeds do NOT require polarization adjustment.
Auto-Polarization mode is the default polarization mode of operation fromthe ACU. Polarization may be operated
manually from the ACU. Refer to the Antenna Control Unit manual (POL TYPE parameter) for more operation
information.
PRELIMINARY

6009-33 Broadband At Sea Operation

2.7. Low Noise Block Converter Operation/Selection:
There are three controls applicable to the LNB's installed on this system; 1 operational voltage selection, 2 operational
tone control and selection of Co-Pol OR Cross-Pol Receive IF. Voltage and Tone, used to select the frequency band of
the LNB, are supplied to the LNB which has been selected by the Co-Pol/Cross-Pol switch. DC voltage is supplied by
the pedestal modem and Tone is supplied by the tone generator. The Band and Polarity of the Receive IF is selected
by the Tracking Band setting in the ACU. Your service provider will determine which frequency band and whether to
use Co-Pol or Cross-Pol for normal operation. The chart below may be used to determine what tracking band setting
to utilize and only applies when the “TrackDisp” parameter is set to 0130 (refer to chapter 5 for detailed information
on this parameter).
Tracking Band Setting Tone, LNB Voltage & Switch state Receive IF Polarity
Xp B1 Tone OFF, Volt 13, Aux 0 Cross-Pol Band 1
Xp B2 Tone ON, Volt 13, Aux 0 Cross-Pol Band 2
Xp B3 Tone OFF, Volt 18, Aux 0 Cross-Pol Band 3
Xp B4 Tone ON, Volt 18, Aux 0 Cross-Pol Band 4
Cp B1 ToneOFF, Volt 13, Aux 1 Co-Pol Band 1
Cp B2 Tone ON, Volt 13, Aux 1 Co-Pol Band 2
Cp B3 ToneOFF, Volt 18, Aux 1 Co-Pol Band 3
Cp B4 Tone ON, Volt 18, Aux 1 Co-Pol Band 4
2.8. RF Equipment
The RF Equipment is not operated or controlled by the antenna pedestal or Antenna Control Unit. Refer to the vendor
supplied manuals for the RF Equipment and Satellite Modem which were provided with your system.
2.9. FCC TX Mute Function
FCC TX Mute function provides a transmit inhibit, or mute, signal to the Satellite Modem to disable transmit whenever
the antenna is blocked, searching, targeting, unwrapping, or is mispointed >0.5 degrees from peak satellite position.
This functionality is provided by software in the ACU & PCU. Hardware wiring connection between the ACU Terminal
Mounting Strip and the Satellite Modem and proper setup of the ACU “SYSTEM TYPE” parameter are also required for
this function to operate properly.
After being properly installed and setup correctly the FCC TX Mute function operation is automatic, therefore, requires
no operator intervention. Refer to the Installation and Setup chapters in this manual and in your Antenna Control Unit
manual.
2.10. Radome Assembly Operation
When operating the system it is necessary that the radome access hatch (and/or side door) be closed and secured in
place at all times. This prevents rain, salt water and wind from entering the radome. Water and excessive
condensation promote rust & corrosion of the antenna pedestal. Wind gusts will disturb the antenna pointing.
There are no other operating instructions applicable to the radome assembly by itself.

3. Installation
Your antenna pedestal comes completely assembled in its radome. This section contains instructions for unpacking, final
assembly and installation of the equipment. It is highly recommended that installation of the system be performed by trained
technicians.
3.1. Unpacking and Inspection
Exercise caution when unpacking the equipment. Carefully inspect the radome surface for evidence of shipping
damage.
3.2. Site Selection Aboard Ship
The radome assembly should be installed at a location aboard ship where:
•The antenna has a clear line-of-sight to as much of the sky (horizon to zenith at all bearings) as is practical.
•The antenna is a minimum of 15 Feet from the ship's Radar, further away if they arehigh power Radar arrays.
•The antenna is not mounted on the same plane as the ship's Radar, so that it is not directly in the Radar beam
path.
•The antenna isa minimum of 15 Feet from high power short wave transmitting antennas.
•The Above Decks Equipment (ADE) and the Below Decks Equipment (BDE) should be positioned as close to
one another as possible. This is necessary to reduce the losses associated with long cable runs.
•The mounting location is robust enough that it will not flex or sway in ships motion and be sufficiently well
re-enforced to prevent flex and vibration forces from being exerted on the antenna and radome.
•If the radome is to be mounted on a raised pedestal, it MUST have adequate gussets, or be well guyed, to
prevent flexing or swaying in ships motion. Robust,.
•This mounting platform must also be robust enough to withstand the forces exerted by full rated wind load
on the radome.
If these conditions cannot be entirely satisfied, the site selection will inevitably be a “best” compromise between the
various considerations.
3.3. Assembly Notes and Warnings
NOTE: Unless otherwise indicated, all nuts and bolts should be assembled
with Loctite 271 or its equivalent.
WARNING: Assure that all nut & bolt assemblies are tightened according the tightening

3.4. Installing the ADE
The antenna pedestal is shipped completely assembled in its radome.
WARNING: Hoisting with other than a webbed four-part sling may result in catastrophic crushing
of the radome. Refer to the specifications and drawings for the fully assembled weight of your
model Antenna/Radome and assure that equipment used to lift/hoist this system is rated
accordingly.
CAUTION: The antenna/radome assembly is very light for its size and is subject to large swaying
motions if hoisted under windy conditions. Always ensure that tag lines, attached to the radome
base frame, are attended while the antenna assembly is being hoisted to its assigned location
aboard ship.
WARNING: Assure that all nut & bolt assemblies are tightened according the tightening torque

Preparing The Single Piece 80.8” Radome Assembly
2. Remove the shipping hold-down bolts which mount the ADE to its’ pallet.
3. Attach a four-part lifting sling to the four lifting eyes in
the base of the radome and lift the radome
assembly free of its shipping pallet. Place the radome
assembly on temporary support blocks at least 22 inches
high.
4. Loosely assemble the radome base frame's eight
legs and eleven braces as shown in the Radome Base
Frame Assembly drawing using the hardware
provided. Insure that a split washer is used under
each nut. When assembled, tighten all hardware.
5. Using the four-part lifting sling, and with a tag line
attached to the radome base frame, hoist the antenna
assembly to its assigned location aboard ship by means
of a suitably-sized crane or derrick.
6. The radome assembly should be positioned with
the BOW marker aligned as close as possible to the ship centerline. Any variation from actual
alignment can be compensated with the AZIMUTH TRIM adjustment in the ACU, so precise
alignment is not required.

7. Bolt or weld the legs of the radome base frame directly to the ship's deck. If the deck is uneven or
not level, weld clips to the deck and attach them to the legs of the radome base frame. When
completed the radome base must be level.
8. Disconnect the lifting sling from the four lifting eyes in the base of the radome.
3.4.2.
1. Open the radome hatch (if you didn’t previously) and enter part way into the radome.
Antenna Pedestal Mechanical Checklist
2. Inspect the pedestal assembly and reflector for signs of shipping damage.
3. Remove the tiewrap(s) and web strap(s) that are restraining the pedestal. Save the web strap
shipping restraints so that they can be re-used to restrain the antenna if the system will
be un-energized while the ship is underway.
4. Check to assure that the antenna moves freely in azimuth without hitting any area of the interior of
the radome or fouling in any of the cables in the base of the radome. Elevation and cross are held
by the brakes built into those motors.
5. Check that all pedestal wiring and cabling is properly dressed and clamped in place.
6. Assure that the radome hatch is closed and secured when entry into the radome is no longer
required.
3.5. Cable Installation
3.5.1.
Shipboard Cable Installation
CAUTION:Rough handling, tight bending, kinking, crushing and other careless
handling of the cables and their connectors can cause severe damage.
The cables must be routed from the above-decks equipment group through the deck and through various ship
spaces to the vicinity of the below-decks equipment group. When pulling the cables in place, avoid sharp
bends, kinking, and the use of excessive force. After placement, seal the deck penetration gland and tie the
cables securely in place.

4. Set-up & Configuration
The components in the system will have been configured with IP Addresses at the factory. The Front Title Page of this manual
has a list of recorded IP address information, serial number information and Modem software version.
In the paragraphs below you will verify the configuration of these components, which will also verify that each of them are
communicating. If one of the components has been replaced, it will have to be configured correctly to properly operate as part
of this system.
Contact Sea Tel for the Internet Service Provider (ISP) Network Operation Center (NOC) ASSIGNED IP address, SubNet Mask
and the Primary & Secondary DNS addresses if they have not been previously provided to you, or if you have changed
providers.
4.1. Operator Settings
Refer to the Operation chapter of this manual to set the Ship information. Latitude and Longitude should
automatically update when the GPS engine mounted above decks triangulates an accurate location, but you may enter
this information manually to begin. If your gyro source is providing Heading information in any format other than
NMEA-0183 format, you will have to enter in the initial Ship’s Heading position, the Gyro Compass will then keep the
ACU updated.
Set the Satellite information, for the satellite you will be using. The receiver settings are especially important. At this
point you should be able to target the desired satellite. Continue with the setup steps below to optimize the
parameters for your installation.
4.2. Optimizing Targeting
First, assure that all of your Ship & Satellite settings in the ACU are correct. Target the desired satellite, immediately
turn Tracking OFF, and record the Azimuth and Elevation positions in the “ANTENNA“ display of the ACU (these are
the Calculated positions). Turn Tracking ON, allow the antenna to “Search” for the targeted satellite and assure that it
has acquired (and peaks up on) the satellite that you targeted. Allow several minutes for the antenna to “peak” on the
signal, and then record the Azimuth and Elevation positions while peaked on satellite (these are the Peak positions).
Again, assure that it has acquired the satellite that you targeted!
Subtract the Peak Positions from the Calculated Positions to determine the amount of Trim which is required. Refer to
the ACU Setup information to key in the required value of Elevation Trim. Continue with Azimuth trim, then re-target
the satellite several times to verify that targeting is now driving the antenna to a position that is within +/- 1.0 degrees
of where the satellite signal is located.
EXAMPLE: The ACU targets to an Elevation position of 30.0 degrees and an Azimuth position of 180.2 (Calculated),
you find that Peak Elevation while ON your desired satellite is 31.5 degrees and Peak Azimuth is 178.0. You would
enter an EL TRIM value of –1.5 degrees and an AZ TRIM of +2.2 degrees. After these trims values had been set, your
peak on satellite Azimuth and Elevation displays would be very near 180.2 and 30.0 respectively.
4.3. Optimizing Auto-Polarization TX/RX
If your system is fitted with a circular feed you do not need to optimize the polarity angle and can skip this procedure.
This procedure optimizes the linear polarization of the feed. Verify that tracking is ON and that the antenna is peaked
on your targeted satellite (targeting calculates the azimuth, elevation and polarization angles). Assure that you are in
Auto-Pol mode (POL TYPE parameter in the ACU is set to 0072) and set your satellite modem (or spectrum analyzer) to
view its signal level display. Go to the TX POLARITY parameter in the Setup menu of the ACU and set this parameter
to your assigned Transmit polarity (Horizontal or Vertical). Go to the POL OFFSET parameter in the Setup menu of the
ACU.
Default setting is 0040 and may be incremented, or decremented, to adjust polarization while in Auto-Pol mode. Each
increment equals one degree of polarization rotation (0048 = +8 degrees), decrement below 40 for minus polarization
(0032 = -8 degrees). Press the UP arrow to increment or the DOWN arrow to decrement the value and then hit the
ENTER key to adjust the feed to the new value. Allow 30 to 60 seconds between increments or decrements to allow
time for feed assembly to drive to new position
During commissioning, under guidance from the network operation center, you will be adjusting to minimize the effect
of your transmission on the opposite polarization which maximizes your Cross-Pol isolation. Contact your satellite
provider to help you (over the phone) to optimize the polarity angle for maximum Cross-Pol isolation (this optimizes

your transmit polarity and is much more accurate than you trying to optimize your receive polarity). Save your new
TX POLARITY and POL OFFSET values (refer to Save New Parameters in your ACU manual).
4.4. Calibrating Relative Antenna Position (Home Flag Offset)
During initialization, azimuth drives the CW antenna until the Home Switch is contacted, which “presets” the relative
position counter to the value stored in the Home Flag Offset. This assures that the encoder input
increments/decrements from this initialization value so that the encoder does not have to be precision aligned.
The Home Switch is a hall sensor which is actuated by a magnet mounted on the azimuth driven sprocket, which
produces the “Home Flag” signal.
The Home Flag Offset is a value saved in NVRam (Non-Volatile RAM) in the PCU. This value is the relative position of
the antenna when the home switch is engaged. Presetting the counter to this value assures that when the antenna is
pointed in-line with the bow of the ship the counter will read 000.0 Relative (360.0 =000.0).
In most cases when the antenna stops at the home
flag, it will be pointed in-line with the Bow of the ship.
In these cases Home Flag Offset (HFO) should be set
to zero. When “Optimizing Targeting” small variations
(up to +/- 5.0 degrees) in Azimuth can be corrected
using If it AZ TRIM as described in the Optimizing
Targeting procedure above.
Large variations in Azimuth position indicate that the
Relative position is incorrect and should be
“calibrated” using the correct HFO value instead of an
Azimuth Trim offset. This is especially true if sector
blockage mapping is used.
If the antenna stops at the home flag, but it is NOT
pointed in-line with the Bow of the ship, it is
important to assure that the antennas actual position
(relative to the bow of the ship) is the value that gets
“preset” into the Relative position counter. By saving
the antennas actual Relative position when at the
home flag into HFO, you have calibrated the antenna
to the ship.
4.4.1.
If Targeting has been optimized by entering a large value of AZ TRIM; First, verify that you are able to
repeatably accurately target a desired satellite (within +/- 1.0 degrees). Then you can use the AZ TRIM value
to calculate the value of HFO you should use (so you can set AZ TRIM to zero). AZ Trim is entered as the
number of tenths of degrees. You will have to convert the AZ TRIM value to the nearest whole degree
(round up or down as needed). Calculated HFO value is also rounded to the nearest whole number.
To Calculate HFO:
If AZ TRIM was a plus value: HFO = (TRIM / 360) x 255 Example: AZ TRIM was 0200 (plus 20 degrees).
HFO = (20/360) x 255 = (0.0556) x 255 = 14.16 round off to 14.
If AZ TRIM was a negative value: HFO = ((360-TRIM) / 360)) x 255 Example: AZ TRIM = -0450 (minus 45
degrees). HFO = ((360 – 45) / 360)) x 255 = (315 / 360) x 255 = 0.875 x 255 = 223.125 round of to 223.
If Targeting has NOT been optimized, allow the antenna to initialize to its home flag position. Visually
compare the antennas pointing to the bow-line of the ship (parallel to the Bow). Note the antennas position
relative to the Bow. If it appears to be very close to being parallel to the bow, HFO will probably not be
needed and you can proceed with Optimizing Targeting. If it is NOT close [initialization was driving the
azimuth CW], note if the antenna appears to have stopped before it got to the Bow or if it went past the Bow.
You may be able to guess an approximate amount of how many degrees the antenna is from the bow. This is
only intended to help you initially find the satellite (which direction you will have to drive and approximately
how far you will have to drive). Refer, in general terms, to the Optimizing Targeting procedure.
