INSTALLATION AND OPERATION MANUAL

FOR SEA TEL MODEL

9711-44 KU-BAND TX/RX ANTENNA

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. Prior to work on

the stabilized antenna system, the power to the transmit/receive system must be locked

out and tagged.

When the transmit/receive system is in operation, no one should be allowed anywhere

within the radiated beam being emitted from the reflector.

The ultimate responsibility for safety rests with the facility operator and the

individuals who work on the system.

These commodities, technology or software were exported from the United

States in accordance with the Export Administration Regulations. Diversion

contrary to U.S. law is prohibited.

Sea Tel Marine Stabilized Antenna systems are manufactured in the United

States of America.

FCC Declaration of Conformity

1. Sea Tel, Inc. designs, develops, manufactures and services marine stabilized antenna systems for

satellite communication at sea. These products are in turn used by our customers as part of their Ku-

band Earth Station on Vessels (ESV) networks.

2. FCC regulation 47 C.F.R. § 25.222 defines the provisions for blanket licensing of ESV antennas

operating in the Ku Band. This declaration covers the requirements for meeting § 25.222 (a)(1) by

the demonstrations outlined in paragraphs (b)(1)(i) and (b)(1)(iii). The requirements for meeting §

25.222 (a)(3)-(a)(7) are left to the applicant. The paragraph numbers in this declaration refer to the

2009 version of FCC 47 C.F.R. § 25.222.

3. Sea Tel hereby declares that the antennas listed below will meet the off-axis EIRP spectral density

requirements of § 25.222 (a)(1)(i) with an N value of 1, when the following Input Power spectral

density limitations are met:

*0.6 Meter Ku Band, Models 2406 and USAT-24 are limited to -21.6 dBW/4kHz

*0.75 Meter Ku Band, Models 3011 and USAT-30 are limited to -21.6 dBW/4kHz

0.9 Meter Ku Band, Model 3612 is limited to -20.3 dBW/4kHz

1.0 Meter Ku Band, Models 4003/4006/4009/4010 are limited to -16.3 dBW/4kHz

1.0 Meter Ku Band Model 4012 is limited to -16.6 dBW/4kHz

1.2 Meter Ku Band, Models 4996/5009/5010/5012 are limited to -14.0 dBW/4kHz

1.5 Meter Ku Band, Models 6006/6009/6012 are limited to -14.0 dBW/4kHz

2.4 Meter Ku Band, Models 9797 and 9711QOR are limited to -14.0 dBW/4kHz

4. Sea Tel hereby declares that the antennas referenced in paragraph 3 above, will maintain a

stabilization pointing accuracy of better than 0.2 degrees under specified ship motion conditions,

thus meeting the requirements of § 25.222 (a)(1)(ii)(A). Those antennas marked with * will

maintain a stabilization pointing accuracy of better than 0.3 degrees. The Input Power spectral

density limits for these antenna have been adjusted to meet the requirements of§ 25.222 (a)(1)(ii)(B).

5. Sea Tel hereby declares that the antennas referenced in paragraph 3 above, will automatically cease

transmission within 100 milliseconds if the pointing error should exceed 0.5 degrees and will not

resume transmission until the error drops below 0.2 degrees, thus meeting the requirements of §

25.222 (a)(1)(iii).

6. Sea Tel maintains all relevant test data, which is available upon request, to verify these declarations.

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 C-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. Other Inputs to the System

Multi-conductor cables from Ship’s Gyro Compass, GPS, phone, fax and computer equipment may be connected in the

system.

1.4. System Components

The Series 11 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.

1.5. Dual Antenna Configuration

Sometimes, due to very large blockage conditions, you may need to install a dual antenna configuration to provide

uninterrupted services. Two full antenna systems are installed and the ACU control outputs are connected to an

arbitrator switch panel which then is connected to the below decks equipment. NOTE: The RXIF from EACH antenna

MUST be connected to the RF IN (J6) on the rear panel of its respective ACU then RFOUT (J7) is connected to the RXIF

input of the Dual Antenna Arbitrator. This connection scheme is required for ACU “A” to be able to control Antenna

“A” (and ONLY Antenna “A”) AND ACU “B” to be able to control Antenna “B” (and ONLY Antenna “B”).

You will program the blockage zone(s) for each of the two antennas (refer to Setup – Blockage Zones). The blockage

output from the ACU is fed to the Terminal Mounting Strip so that the output of each ACU can be connected to the

arbitrator panel to control it. The blockage output is available on SW2 terminal of the Terminal Mounting Strip to

provide a transistor “short” to ground when the antenna is within a blockage zone programmed into the ACU. When

not blocked the SW2 terminal will be an “open”.

When one antenna is blocked, its blockage output will command the arbitrator panel to switch services to the modem

from that antenna to the other antenna. The arbitrator panel provides a logic latch to prevent excess switching when

the ship heading is yawing, therefore, causing if the antenna to be repeatedly blocked – unblocked – blocked.

9711-44 Ku-Band TXRX Introduction

1-3

1.6. Dual Antenna Arbitrator

The Dual Antenna Arbitrator panel can pass LNB voltages (and handle 250-400 ma of current) and the RXIF signals on

the RX connections. TXIF, Reference and BUC supply voltage can pass through this arbitrator panel to the antenna, but

it is not recommended that BUC power be supplied through the dual channel rotary joint of the antenna (a BUC power

supply is provided on all Series 09 antenna pedestals).

The blockage (SW2) output, GPS output and modem lock input from the two terminal mounting strips (antenna “A”

and antenna “B”) are wired through the arbitrator panel to the satellite modem. When antenna “A” is blocked, the

arbitrator PCB will toggle the coax switches so that antenna “B” provides signal to the BDE distribution (multi-switch or

modem). When antenna “A” is no longer blocked the arbitrator will do nothing (because it is a latch circuit). When

antenna “B” is blocked the panel will switch so that antenna “A” is again providing signal the BDE distribution.

To provide a seamless switching transition, refer to the arbitrator installation instructions to balance the TX and RX

signal levels between the two antennas.

1.7. Open Antenna-Modem Interface Protocol (OpenAMIP™) Specification:

1.7.1. Overview:

OpenAMIPTM, an ASCII message based protocol invented and Trademarked by iDirect is a specification for

the interchange of information between an antenna controller and a satellite modem. This protocol allows

the satellite modem to command the ACU (via TCP port 2002) to seek a particular satellite as well as allowing

exchange of information necessary to permit the modem to initiate and maintain communication via the

antenna and the satellite. In general, OpenAMIPTM is not intended for any purpose except to permit a

modem and the ACU to perform synchronized automatic beam switching. It is NOT a status logging system

or a diagnostic system. In addition, OpenAMIPTM is intended for a typical installation whereby a specific

satellite modem and Antenna system are properly configured to work together. The protocol does not make

specific provisions for auto-discovery or parameter negotiation. It is still the responsibility of the installer to

ensure that the parameters of both the satellite modem (proper option files) and the ACU/PCU (setup

parameters) are actually compatible for the intended satellite(s).

9711-44 Ku-Band TXRX Site Survey

2-1

2. Site Survey

There are three objective of the site survey. The first is to find the best place to mount the antenna and the BDE. The second is

to identify the length and routing of the cables and any other items or materials that are required to install the system. The third

is to identify any other issues that must be resolved before or during the installation.

2.1. Site Selection Aboard The Ship

The radome assembly should be installed at a location aboard ship where:

•The antenna has a clear line-of-sight to view as much of the sky (horizon to zenith at all bearings) as is practical.

•X-Band (3cm) Navigational Radars:

•The ADE should be mounted more than 0.6 meters/2 feet from 2kW (24 km) radars

•The ADE should be mounted more than 2 meters/8 feet from 10kW (72 km) radars

•The ADE should be mounted more than 4 meters/12 feet from 160kW (250km) radars

•S-Band (10cm) Navigational Radars:

•If the ADE is/has C-Band it should be mounted more than 4 meters/12 feet from the S-band Radar.

•The ADE should not be mounted on the same plane as the ship's radar, so that it is not directly in the radar beam path.

•The ADE should be mounted more than 2.5 meters/8 feet from any high power MF/HF antennas (<400W).

•The ADE should be mounted more than 4 meters/12 feet from any high power MF/HF antennas (1000W).

•The ADE should also be mounted more than 4 meters/12 feet from any short range (VHF/UHF) antennae.

•The ADE should be mounted more than 2.5 meters/8 feet away from any L-band satellite antenna.

•The ADE should be mounted more than 3 meters/10 feet away from any magnetic compass installations.

•The ADE should be mounted more than 2.5 meters/8 feet away from any GPS receiver antennae.

•Another consideration for any satellite antenna mounting is multi-path signals (reflection of the satellite signal off of

nearby surfaces arriving out of phase with the direct signal from the satellite) to the antenna. This is particularly a

problem for the onboard GPS, and/or the GPS based satellite compass.

•The ADE and the BDE should be positioned as close to one another as possible. This is necessary to reduce the losses

associated with long cable runs.

•This mounting platform must also be robust enough to withstand the forces exerted by full rated wind load on the

radome.

•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 size, wall thickness and gussets to

prevent flexing or swaying in ships motion. In simple terms it must be robust.

If these conditions cannot be entirely satisfied, the site selection will inevitably be a “best” compromise between the

various considerations.

2.2. Antenna Shadowing (Blockage) and RF Interference

At the transmission frequencies of C and Ku band satellite antenna systems, any substantial structures in the way of

the beam path will cause significant degradation of the signal. Care should be taken to locate the ADE so that it has

direct line-of-sight with the satellite without any structures in the beam path through the full 360 degree ships turn.

Wire rope stays, lifelines, small diameter handrails and other accessories may pass through the beam path in limited

numbers; however, even these relatively insignificant shadows can produce measurable signal loss at these

frequencies.

2.3. Mounting Foundation

2.3.1. Mounting on Deck or Deckhouse

While mounting the ADE on a mast is a common solution to elevate the ADE far enough above the various

obstructions, sometimes the best mounting position is on a deck or deckhouse top. These installations are

inherently stiffer than a mast installation as the design of the deck/deckhouse structure is prescribed by the

ship’s classification society. In the deck/deckhouse design rules, the minimum plating and stiffener guidelines

are chosen to preclude high local vibration amplitudes.

Most installations will have a base frame with multiple attachment points around the perimeter of the base

frame to mount the ADE onto a deck or deckhouse structure of the ship. The base frame may be mounted

using the supplied legs & braces to raise the ADE above the deck for radome hatch access. The base frame

may be directly attached to the deck, in which case the access panel in the floor of the base frame cannot be

utilized. In this case, the installation must allow acces through a door in one of the side panels or an access

opening directly under the hacth. Some care must be taken to ensure the mounting pedestal is properly

aligned with the stiffeners under the deck plating.

Alternately, a specifically designed and stiffened mast may be used to mount the base frame above the deck;

although, this should only be attempted if sufficient deck space high on the ship is not available.

2.3.2. ADE Mounting Considerations

Mounting the radome directly on the deck, or platform prevents access to the hatch in the base of the

radome unless an opening is designed into the mounting surface to allow such entry. If there is no access to

the hatch the only way to service the antenna is to remove the radome top.

Ladder rungs must be provided on all mounting stanchions greater than 3-4 feet tall to allow footing for

personnel safety when entering the hatch of the radome.

The recommended cable passage is through the bottom (near center) of the radome base, down through the

ADE support pedestal (if used), through the deck and into the interior of the ship.

2.3.3. Sizing of the support pedestal

The following should be taken into account when choosing the height of a mounting support stand:

1. The height of the pedestal should be kept as short as possible, taking into account recommendations

given in other Sea Tel Guidelines.

2. The minimum height of the pedestal above a flat deck or platform to allow access into the radome

for maintenance should be 0.6 meters (24 inches).

3. The connection of the ADE mounting plate to the stanchion and the connection of the pedestal to

the ship should be properly braced with triangular gussets (see graphic above). Care should be taken

to align the pedestal gussets to the ship’s stiffeners as much as possible. Doublers or other

reinforcing plates should be considered to distribute the forces when under-deck stiffeners are

inadequate.

4. The diameter of the pedestal stanchion shall not be smaller than 100 millimeters (4 inches). Where

the ADE base diameter exceeds 1.5 meters (60 inches), additional stanchions (quantity greater than

3) should be placed rather than a single large stanchion.

5. Shear and bending should be taken into account in sizing the ADE mounting plate and associated

gussets.

6. Shear and bending must be taken into account when sizing the pedestal to ship connection.

7. All welding should be full penetration welds –V-groove welds with additional fillet welds – with

throats equivalent to the thickness of the thinnest base material.

8. For an ADE mounted greater than 0.6 meters (24 inches) above the ship’s structure, at least one (1)

foot rung should be added. Additional rungs should be added for every 0.3 meter (12 inches) of

pedestal height above the ship’s structure.

9. For an ADE mounted greater than 3 meters (9 feet) above the ship’s structure, a fully enclosing cage

should be included in way of the access ladder, starting 2.3 meters (7 feet) above the ship’s

structure.

2.4. Mounting Height and Fore-Aft Location

Installations with mast or deck vibrations at frequencies between 2 and 15 Hertz have been identified by Sea Tel as

causing problems with the isolation systems of the ADE. Preventing problems prior to installation due to these

vibrations is one of the primary considerations in choosing where to mount the antenna.

In some installations, though, the combination of mounting height, fore-aft location and ship motion can impart

significant accelerations on the entire ADE. Installations where the ADE is situated high on the ship – usually at the

top of a mast – places the ADE is a position where the low frequency ship motion in roll and/or pitch creates two

accelerations – tangential and radial. These accelerations vary in a periodic function, out-of-phase from the ship

response to the wave motions.

Radial acceleration is the acceleration acting on the mass of the ADE pulling away from the center of the axis (roll or

pitch). In this sense, it would be a force trying to ‘pull’ the ADE away from the ship. We normally are not too

concerned with radial acceleration, since it must become far greater than gravity to have a detrimental effect on the

ADE.

Tangential acceleration is the acceleration acting on the mass of the ADE pulling across the center of the axis (roll or

pitch). This acceleration becomes a force trying to pull the ADE to the side. The tangential acceleration has an effect

on both the strength of the ADE pedestal and the tracking accuracy of the control algorithm.

The effect of tangential acceleration is felt by the structure of the ADE before it truly affects the tracking accuracy.

For instance, Sea Tel normally accepts that a tracking error of 0.1 degrees RMS at 0.5 G to be within acceptable error

margins. A 0.5 G tangential acceleration on the ADE means that ½ of the weight of the ADE is acting sideways on the

pedestal structure.

The higher up you mount the antenna above the pivot point of the ship the higher the tangential acceleration (g-

force) exerted on the antenna will be (see chart below). When the g-force exerted on the antenna is light, antenna

stabilization and overall performance will not be affected.

If the g-force exerted on the antenna is high enough (> 1 G), antenna stabilization and overall performance will be

affected.

If the g-force exerted on the antenna is excessive (1-2 Gs), the antenna will not maintain stabilization and may even

be physically damaged by the g-force.

2.5. Mast Configurations

Sea Tel recommends the ADE be mounted on the ship in a location which has both a clear line-of-sight to the target

satellites in all potential azimuth/elevation ranges and sufficient support against vibration excitement. If possible,

mounting the ADE pedestal directly to ship deckhouse structures or other box stiffened structures is preferred.

However, in many cases, this imposes limits on the clear line-of-sight the antenna system has.

Site Survey 9711-44 Ku-Band TXRX

2-4

Often the solution for providing the full azimuth/elevation range the antenna needs is to mount the ADE on the ship’s

mast. Unfortunately, masts do not consider equipment masses in design and often have harmonic frequencies of their

own.

For these large systems, the mast for the ADE should be designed specifically for the ADE. Other equipment may be

mounted alongside, but the mast should be configured to accept the mass, loads and resonance of the ADE primarily.

The following sections describe various mast configurations and some considerations for mast design.

2.5.1. Vertical Masts

Vertical masts are a very ancient and common mast design. In essence, it is the mast derived from the sailing

mast and adapted for mounting the ever-increasing array of antennae which ships need to communicate with

the world. This drawing of a vertical mast shows

the preferred mounting of the ADE center-line

above the plane of the radar. Alternatively the ADE

is mounted below the plane of the radar signal

Vertical masts are most commonly found on cargo

ships – they are simple, inelegant and functional.

They are also fairly stiff against torsional reaction

and lateral vibrations, as long as the ADE is

mounted on a stiff pedestal near the vertical

centerline of the mast. If centerline mounting is

impractical or otherwise prohibited, the mast

platform the ADE is mounted on should be checked

for torsional vibration about the centerline of the

mast and the orthogonal centerline of the platform.

If the estimated natural frequency of the mast or platform is less than 35 Hertz, the mast or platform should

be stiffened by the addition of deeper gussets under the platform or behind the mast.

2.5.2. Raked Masts

Raked masts are found on vessels where the style

or appearance of the entire vessel is important.

Again, the inclined mast is a direct descendant from

the masts of sailing ships – as ship owners wanted

their vessels to look more unique and less

utilitarian, they ‘raked’ the masts aft to make the

vessel appear capable of speed. This drawing

shows a raked mast, again with the preferred ADE

mounting above the radar and alternate with the

ADE below the radar.

Raked masts pose special problems in both

evaluating the mast for stiffness and mounting of

antennae. As can be seen in the drawing, all

antennae must be mounted on platforms or other

horizontal structures in order to maintain the

vertical orientation of the antenna centerline. This

implies a secondary member which has a different

natural frequency than the raked mast’s natural frequency. In order to reduce the mass of these platforms,

they tend to be less stiff than the main box structure of the raked mast. Thus, they will have lower natural

frequencies than the raked mast itself. Unfortunately, the vibratory forces will act through the stiff structure

of the raked mast and excite these lighter platforms, to the detriment of the antenna.
