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.

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 be passed 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 & RX signal
levels between the two antennas.
1.7. Open Antenna-Modem Interface Protocol (OpenAMIP™) Specification:
1.7.1.
OpenAMIP, 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, OpenAMIP is not intended for any purpose except to permit a modem
and the ACU to perform synchronized automatic beam switching. It is
Overview:
NOT a status logging system or a
diagnostic system. In addition, OpenAMIP is intend 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 assure

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

2. Site Survey
The objective of the Site survey is to find the best place to mount the antenna & the below decks equipment, the length and
routing of the cables and any other items or materials that are required to install the system and identify any other issues that
must be resolved before or during the installation. For Naval Engineering level information on this subject, please refer
to Antenna Installation Guideline – Site Arrangement, document number 130040_A available on the Sea Tel
Dealer Support Site.
2.1. 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 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 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.
•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 the ADE
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.
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.
Mounting on Deck or Deckhouse
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.
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.
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).
ADE Mounting Considerations
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.
The following should be taken into account when choosing the height of a mounting support stand:
Sizing of the support pedestal
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.

Site Survey 4009-33 Installation Manual
2-3
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 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.
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 just 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:

4009-33 Installation Manual Site Survey
2-4
2.5.1.
Vertical masts are a very ancient and common mast design. In essence, it is the mast derived from the sailing
mast, adapted for mounting the ever-increasing array of antennae ships need to communicate with the
world. This drawing of a Vertical mast shows
preferred mounting of the ADE center-line above
the plane of the radar, or as an alternate with the
ADE mounted below the plane of the radar signal,
as reasonably good installations of a satellite
antenna ADE.
Vertical Masts
Vertical masts are most commonly still 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 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
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 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.
2.5.3.
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.
Girder Masts
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

Site Survey 4009-33 Installation Manual
2-5
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 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 is mounted. A
typical truss mast is shown in this photograph.
Truss Mast
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, though, 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.
The access hatch for the ADE shall be oriented aft, or inboard, when practicable. 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 would be 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 also be properly mounted for shipboard use.
Plans to allow access to the rear of the should be considered.
2.8. Cables
During the site survey, walk the path that the cables will be installed along. Pay particular attention to how cables will
be installed all along the path, what obstacles will have to have 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 cables 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. Cables passing through bulkheads or decks shall be routed
through approved weather tight glands.

4009-33 Installation Manual Site Survey
2-6
2.8.1.
The first concern about 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.
ADE/BDE Coaxial Cables
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.
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 not required to be from a UPS
(same one that supplies power to the below decks equipment), but it is recommended.
Antenna Power Cable
2.8.3.
If your system includes a marine air conditioner (available with the 81 inch radome ONLY), run an AC power
cable to it from a breaker, preferably from a different phase of the electrical system than supplies power to
the ADE & BDE. Be EXTREMELY cautious of length of the run for voltage loss and gauge of the wires for the
current that is expected to be drawn.
Air Conditioner Power Cable
2.8.4.
The AC power for the ACU and other below decks equipment is not required to be from a UPS (same one that
supplies power to the ADE), but it is recommended.
ACU Power Cable/outlet
2.8.5.
Use good quality shielded cable (twisted pairs, individually foil wrapped, outer foil with braid overall is best)
You only need 2-wire for NMEA signal, 4-wire for Step-By-Step and 5-wire for Synchro … always use shielded
cable. Be cautious of length and gauge of the run for voltage loss issues.
Gyro Compass Cable
2.9. Grounding
All metal parts of the ADE shall be grounded to bare metal at the mounting pedestal. Grounding straps from the base
of the ADE to a dedicated lug on the mounting pedestal are preferred, but grounding may also be accomplished by
exposing bare metal under all mounting bolts prior to final tightening. Preservation of the bare metal should be done
to prevent loss of ground.
Grounding should be ensured throughout the entire mounting to the hull. While it is presumed the deckhouse is
permanently bonded and grounded to the hull, in cases where the deckhouse and hull are of different materials a
check of an independent ground bonding strap should be made. Masts should be confirmed to be grounded to the
deckhouse or hull.
