1.4. Simplified Block Diagram of a Series 09 System
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.

1.5. Dual Antenna Configuration
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 that is then 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 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”.

09 Series System Configuration(s) 4009-9 Installation Manual
1-3
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.
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).

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 which create signal blockages, sometimes the best mounting position is on a deck or
deckhouse top. These installations are inherently stiffer than a mast installation, if for no other reason
than 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 onto a deck or deckhouse structure will require a mounting pedestal to raise the ADE
above the deck for radome hatch access and to allow the full range of elevation (see ADE mounting
considerations above). Some care must be taken to ensure the mounting pedestal is properly aligned
with the stiffeners under the deck plating.
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.
If there is no access to the hatch, the only way to service
the antenna is to remove the radome top. Two people are
required to take the top off of the radome without
cracking or losing control of it, but even with two people a
gust of wind may cause them to lose control and the
radome top may be catastrophically damaged (see repair
information in the radome specifications).
If access to the hatch cannot be provided in the mounting
surface, provide a short ADE support pedestal to mount
the ADE on which is tall enough to allow access into the
radome via the hatch.
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 in the 50, 60 and 66
inch radomes is through the bottom center of the radome base, down through the ADE support pedestal,
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

Site Survey 4009-9 Installation Manual
2-3
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
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 low, antenna stabilization and overall performance are not affected.
If the g-force exerted on the antenna is high enough (> 1 G), antenna stabilization and overall performance are
affected.
If the g-force exerted on the antenna is excessive (1-2 Gs), the antenna does not maintain stabilization and may be
physically damaged by the g-force.

2.5. Mast Configurations
Sea Tel recommends mounting the ADE in a location that 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 antenna system’s clear line-of-sight.
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.
There are many designs of masts used on ships – masts are nearly as unique in design as the ship is – but the
designs often fall into a few categories. These categories can be addressed in terms of typical responses and
problems with regards to vibration and mounting of ADE. The most common categories of masts are:
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

Site Survey 4009-9 Installation Manual
2-5
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.
2.5.3. Girder Masts
Girder masts are large platforms atop a pair of
columns. Just like girder constructions in
buildings, they are relatively stiff athwart ship – in
their primary axis – but less stiff longitudinally and
torsionally. An example of a girder mast is shown
in this drawing, with the preferred ADE mounting
outboard and above the radar directly on one of
the columns and alternate with the ADE centered
on the girder above the plane of the radar.
The greatest weakness of girder masts is in
torsion – where the girder beam twists about its vertical centerline axis. As with all mast designs
discussed so far, mounting the antenna in line with the vertical support structure will reduce the vibration
tendencies. Mounting the antenna directly above the girder columns provides ample support to the
antenna pedestal and locates the antenna weight where it will influence the natural frequency of the
mast the least.
2.5.4. Truss Mast
Truss masts are a variant on the girder mast
concept. Rather than a pair of columns
supporting a girder beam, the construction is a
framework of tubular members supporting a
platform on which the antennae and other
equipment are mounted. A typical truss mast is
shown in this photograph.
Like a girder mast, truss masts are especially stiff
in the athwart ship direction. Unlike a girder
mast, the truss can be made to be nearly as stiff in
the longitudinal direction. Truss masts are
particularly difficult to estimate the natural
frequency – since a correct modeling includes
both the truss structure of the supports and the
plate/diaphragm structure of the platform. In
general, the following guidelines apply when
determining the adequate support for mounting an antenna on a truss mast:
1. Antenna ADE pedestal gussets should align with platform stiffeners which are at least 200
millimeters in depth and 10 millimeters in thickness.
2. When possible, the antenna ADE pedestal column should align with a vertical truss support.
3. For every 100 kilograms of ADE weight over 250 kilograms, the depth of the platform stiffeners
should be increased by 50 millimeters and thickness by 2 millimeters.
Sea Tel does not have a recommended arrangement for a truss mast – the variability of truss mast
designs means that each installation needs to be evaluated separately.
2.6. Safe Access to the ADE
Safe access to the ADE should be provided. Provisions of the ship’s Safety Management System with regard to
men aloft should be reviewed and agreed with all personnel prior to the installation. Installations greater than 3
meters above the deck (or where the access starts at a deck less than 1 meter in width) without cages around the
access ladder shall be provided with means to latch a safety harness to a fixed horizontal bar or ring.

4009-9 Installation Manual Site Survey
2-6
The access hatch for the ADE shall be oriented aft, or inboard, when practical. In any case, the orientation of the
ADE access hatch shall comply with the SMS guidelines onboard the ship. Nets and other safety rigging under the
ADE during servicing should be rigged to catch falling tools, components or fasteners.
2.7. Below Decks Equipment Location
The Antenna Control Unit, Terminal Mounting Strip and Base Modem Panel are all standard 19” rack mount,
therefore, preferred installation of these items is in such a rack. The ACU mounts from the front of the rack. The
Terminal Mounting Strip and Base Modem Panel mount on the rear of the rack.
The Satellite Modem, router, VIOP adapter(s), telephone equipment, fax machine, computers and any other
associated equipment should be properly mounted for shipboard use.
Plans to allow access to the rear of the ACU should be considered.
2.8. Cables
During the site survey, walk the path where the cables will be installed. Pay particular attention to how cables will
be installed; such as what obstacles they will be routed around, difficulties that will be encountered and the
overall length of the cables. The ADE should be installed using good electrical practice. Sea Tel recommends
referring to IEC 60092-352 for specific guidance in choosing cables and installing cables onboard a ship. Within
these guidelines, Sea Tel will provide some very general information regarding the electrical installation.
In general, all cable shall be protected from chaffing and secured to a cableway. Cable runs on open deck or down
a mast shall be in metal conduit suitable for marine use. The conduit shall be blown through with dry air prior to
passing cable to ensure all debris has been cleared out of the conduit and again after passing the cable to ensure
no trapped moisture exists. The ends of the conduit shall be sealed with cable glands (preferred), mastic or low
VOC silicon sealant after the cables have been passed through.
Cables passing through bulkheads or decks shall be routed through approved weather tight glands.
2.8.1. ADE/BDE Coaxial Cables
The first concern with the coaxial cables installed between the ADE & BDE is length. This length is used
to determine the loss of the various possible coax, Heliax or fiber-optic cables that might be used. You
should always provide the lowest loss cables to provide the strongest signal level into the satellite
modem.
Signal cable shall be continuous from the connection within the ADE radome, through the structure of
the ship to the BDE. Splices, adapters or dummy connections will degrade the signal level and are
discouraged.
Be careful of sharp bends that kink and damage the cable. Use a proper tubing bender for Heliax bends.
Penetrations in watertight bulkheads are very expensive, single cable, welded penetrations that must be
pressure tested.
Always use good quality connectors that are designed to fit properly on the cables you are using. Poor
quality connectors have higher loss, can allow noise into the cable, are easily damaged or fail
prematurely.
In as much as is possible, don’t lay the coaxes on power cables. Try to have some separation from
Inmarsat & GPS cables that are also passing L-band frequencies or radar cables that may inject pulse
repetition noise –as error bits - into your cables.
2.8.2. Antenna Power Cable
Be cautious of length of the run, for voltage loss issues, and assure that the gauge of the wires is
adequate for the current that is expected to be drawn (plus margin). Antenna power is recommended
(but not required) to be from a UPS, generally the same one that supplies power to the below decks
equipment.
