1.1 Introduction
The basic system consists of three units: The terminal, the antenna and the IP handset with
cradle.
1.2 SAILOR 150 FleetBroadband terminal
The terminal is the central unit in the system. It contains all user interfaces and handles all
communication between the BGAN antenna and the local communication units (phones,
computers etc.).
The terminal supplies 18-29 V DC to the antenna through a single coaxial cable.
The DC input for the terminal is designed for both 24 V DC and 12 V DC power supply.
Note
The SAILOR 150 FleetBroadband terminal only works with a
SAILOR 150 FleetBroadband antenna.

2.2 Placing the antenna
2.2.1 Obstructions
The antenna rotates 360° and down to -60° in pitch and roll, to allow for continuous
pointing even in heavy sea conditions. Any objects within this field can cause signal
degradation.
The amount of degradation depends on the size of the object and the distance from the
antenna. As a rule of thumb any object that covers an angle of less than 3° at the antenna
has limited effect. The table below gives a guideline for the distance and maximum size of
blocking objects in order to avoid degradation.
2.2.2 Radiation hazard
The SAILOR 150 FleetBroadband antenna radiates 16.1 dBW EIRP. This translates to a
minimum safety distance of 0.6 m from the antenna while it is transmitting, based on a
radiation level of 10 mW/cm
2
.

2.2.3 Interference
Overview
The antenna must be mounted as far away as possible from the ship’s radar and high power
radio transmitters (including other Inmarsat based systems), because they may
compromise the antenna performance. RF emission from radars might actually damage the
antenna.
The SAILOR FleetBroadband antenna itself may also interfere with other radio systems.
Especially other Inmarsat systems and GPS receivers with poor frequency discrimination
are vulnerable to the radiation generated by the SAILOR FleetBroadband antennas.
Radar
It is difficult to give exact guidelines for the minimum distance between a radar and the
antenna because radar power, radiation pattern, frequency and pulse length/shape vary
from radar to radar. Further, the antenna is typically placed in the near field of the radar
antenna and reflections from masts, decks and other items in the vicinity of the radar are
different from ship to ship.
However, it is possible to give a few guidelines:
Since a radar radiates a fan beam with a horizontal beam width of a few degrees and a
vertical beam width of up to +/- 15°, the worst interference can be avoided by mounting the
antenna at a different level – meaning that the antenna is installed minimum 15° above or
below the radar antenna. Due to near field effects the benefit of this vertical separation
could be reduced at short distances (below approximately 10 m) between radar antenna
and the SAILOR FleetBroadband antenna. Therefore it is recommended to ensure as much
vertical separation as possible when the SAILOR FleetBroadband antenna has to be placed
close to a radar antenna.

Placing the antenna
2-4 Chapter 2: Installing the system 98-129218-B
Radar distance
The minimum acceptable separation (d min.) between a radar and the antenna is
determined by the radar wavelength/frequency and the power emitted by the radar. The
tables below show some “rule of thumb” minimum separation distances as a function of
radar power at X and S band. If the d min. separation listed below is applied, antenna
damage is normally avoided.
“d min.” is defined as the shortest distance between the radar antenna (in any position) and
the surface of the SAILOR FleetBroadband antenna.
The separation distance for C-band (4-8 GHz) radars should generally be the same as for Xband radars.
Radar interference
Even at distances greater than “d min.” in the previous section the radar might still be able
to degrade the performance of the SAILOR FleetBroadband system.
The presence of one or more X-band radars within a radius up to 100 m could cause a
minor degradation of the signal-to-noise ratio during high speed and data calls. The
degradation will be most significant at high radar pulse repetition rates.
As long as receiving conditions are favourable, this limited degradation is without
importance. However, if receiving conditions are poor – e.g. due to objects blocking the
signal path, heavy rainfall or icing, low satellite elevation and violent ship movements – the
small extra degradation due to the radar(s) could cause poor call quality. A voice call might
become noisy or fail while a data connection might decrease in speed and performance.
The presence of S-band radar(s) is unlikely to cause any performance degradation – as long
as the minimum distances (d min.) listed in the previous section are applied.

Placing the antenna
98-129218-B Chapter 2: Installing the system 2-5
Installing the system
It is strongly recommended that interference free operation is verified experimentally
before the installation is finalized.
Other Inmarsat systems
Recommended minimum safe distance to other Inmarsat antennas is 10 m.
GPS receivers
Good quality GPS receivers will work properly very close to the antenna - typically down to
one meter outside the main beam, and down to a few meters inside the main beam.
However, simple GPS receivers with poor frequency discrimination could be affected at
longer range (typically 10 m). It is always recommended to test the GPS performance
before the installation is finalized.
VSAT systems
For optimum performance we recommend a minimum distance of 3 meters from the BGAN
antenna to VSAT antennas.
Auxiliary Terrestrial Component (ATC)
The SAILOR FleetBroadband system is resilient to ATC base stations (future terrestrial
mobile systems) that operate inside the Inmarsat band and that may be located near the
coast.
Other transmitters
See Minimum distance to transmitters on page B-5 in Appendix B for minimum
recommended distance to transmitters in the frequency range below 1000 MHz.
Other precautions
Do not place the antenna close to a funnel, as smoke deposits are corrosive. Furthermore,
deposits on the radome can degrade performance.
CAUTION! The antenna must never be installed closer to a radar than “d
min.” - even if experiments show that interference free operation can be
obtained at shorter distances than “d min.” in the previous section.

2.2.4 Antenna mast design
Overview
The antenna mast must be designed to carry the weight of the antenna unit, which is
approximately 3.9 kg (+ 1.1 kg for the mast mount kit)
The mast must also be able to withstand onboard vibrations and wind forces up to
108 knots on the radome, even in icing conditions.
Antenna mast mounting
Mast mount kit:
The top of the SAILOR 150 FleetBroadband antenna mast should be fitted with the
dedicated mounting kit available from Cobham SATCOM.
Assemble the mast mount kit according to the assembly instruction included with the kit.
The mast mount kit interfaces to a 1½” pipe (OD 48.3 mm). If the supplied plastic sleeve is
omitted, a maximum diameter OD of 52 mm can be used.
Custom mast mounting:
For a custom mast mounting, use 4 M6 bolts (A4) in the threaded bushings on the
175.4 mm diameter circle in the bottom of the antenna. The length of the bolts must be
such that they engage into the bushings of the radome with min. 6 mm and max. 12 mm.
Drill a hole for the cable in the mast flange or use an angled connector.
Mast length and diameter
The placement of the antenna must ensure a rigid structural connection to the hull or
structure of the ship. Parts of the ship with heavy resonant vibrations are not suitable places
for the antenna.
A small platform or short mast shall provide rigid support for the antenna fastening bolts
and a rigid interface to the ship.
If it is necessary to use a tall mast, use the table on page 2-8 to obtain the maximum free
length of the mast. Note that these values depend on rigid antenna-ship interfaces. The
cross-sectional properties and the corresponding maximum free length give a natural
frequency above 30 Hz.
It is recommended to shorten the mast length as much as possible to obtain higher
frequencies. Alternatively, mount stays or wires to stabilize the mast further.
Important
Do not block the drainage hole in the centre bottom of
the antenna.
Placing the antenna
98-129218-B Chapter 2: Installing the system 2-7
Installing the system
High masts or installations on ships with high vibration levels should be further stabilized by
stays or wires from the mast flange. Also mount vibration isolators between the flange and
the radome. For SAILOR 150 FleetBroadband, the vibration isolators are included in the
Mast mount kit.
Note
The table in the next section lists the values for steel masts.
For aluminium masts, the free mast length is reduced to 75% of the values for
steel.
Note
Stays and rigid masts can still not prevent vertical vibration if the mast is attached
to a deck plate that is not rigid. Make every effort to mount the mast on a surface
that is well supported by ribs. If this is not possible, provide extra deck plate
propping.

Antenna mast length
The below table shows the values for a SAILOR 150 FleetBroadband antenna mast
without stays or wires. Note that these values are only guidelines - always consider the
environment and characteristics of the ship before deciding on the mast dimensions.
The mast mount kit interfaces to a 1½” tube (OD 48.3 mm - absolute maximum OD 52
mm). Masts with larger diameters must be tapered and the upper part of the tube
(approximately 50 mm) must have a diameter of 1½”.

2.3 Installing the antenna
2.3.1 Antenna grounding
You may ground the antenna using the mounting bolts.
If the antenna cannot or should not be electrically connected directly to the mounting
surface, you can use a separate grounding cable to make the connection between the
antenna and the common ground to which the terminal is also connected. For example,
you can connect a separate grounding cable when vibration isolators are used at the
mounting bolts.
To obtain a good ground connection, the metal underneath the head of at least one bolt
must be clean of insulating protective coating and a serrated washer should be used. After
tightening the bolts we recommend that you seal the area suitably in order to avoid
corrosion of the grounding point.
Use stainless steel bolts and washers.
For further grounding information read Appendix C Grounding and RF protection on
page C-1.
2.3.2 Antenna cables
Guidelines
A coaxial cable for connection between the antenna and terminal is delivered with the
system. If you need a different cable, make sure that the cable meets the requirements.
Preferably choose one of the cable types in Recommended antenna cables below.
Select a suitable area for installation of the terminal, antenna and cradle. Where the cables
are exposed to mechanical wear - on deck, through bulkheads, etc. - protect the cables with
steel pipes. Otherwise, follow standard procedures for cabling in ship installations.
The maximum allowed RF-loss in the antenna cable is 20 dB at 1660 MHz. This is to ensure
the performance of the system.
Recommended antenna cables
The table below shows recommended cable types and maximum cable lengths for
SAILOR 150 FleetBroadband.
Cable Type Absolute maximum length
G02232-D 6 m

Installing the antenna
2-10 Chapter 2: Installing the system 98-129218-B
Check in the data sheet from the cable supplier that both the RF- attenuation and the DCresistance are kept within the maximum specified values:
• Antenna cable RF-attenuation at 1660 MHz: max. 20 dB incl. connector.
• Antenna cable modem-attenuation at 54 MHz: max. 4 dB.
Antenna cable modem-attenuation at 36 MHz: max. 3 dB.
• Antenna cable loop DC-resistance max: 1 .
Also ensure that the specified minimum bending radius is respected. If this is not the case,
the loss in the cable will increase. Check the instructions from the cable supplier.
2.3.3 Important mounting notes
Line of sight
Place the antenna with free line of sight in all directions to ensure proper reception of the
satellite signal. Do not place the antenna close to large objects that may block the signal.
Water intrusion
After having connected the antenna cable to the antenna, ensure that the connector
assembly is properly protected against seawater and corrosion. As a minimum, use selfamalgamating rubber.
If possible, install the radome such that direct spray of sea water is avoided.
It is recommended not to use pneumatic tools for cleaning the radome, especially at a short
distance and directly at the split between top and bottom.
Note that the SAILOR 150 FleetBroadband antenna is drained for condensation through
the gasket in the bottom centre. Make sure the requirements to drainage are met. See the
next section Condensation.
Condensation
In some cases there will be condensation inside the radome. The gasket in the bottom
centre of the SAILOR 150 FleetBroadband antenna is designed to lead any water away
from the radome.

2.3.4 Mounting the antenna
The radome can now be installed on the ship with 4 stainless steel bolts fastened to the hull
or to a mast.
For information on mast mounting, see Antenna mast design on page 2-6.
Mounting the antenna on the hull
Make sure the antenna has line of sight to the satellites. When the antenna is mounted
directly on the hull, it may be difficult to obtain line of sight, especially down to -60°, which
is the maximum rotation angle (pitch and roll) for the SAILOR 150 FleetBroadband antenna.
Use M6 bolts for mounting the antenna.
The bolt thread must not penetrate more than 12 mm (or 8 turns of the bolt) - and not less
than 6 mm (or 4 turns of the bolt)- into the threaded part of the bushings in the radome.
Fasten the bolts with 7-8 Nm torque.
The only electrical connector is a single TNC-connector in the bottom of the radome.
Important
Do not block the drainage hole in the centre bottom of
the antenna.
Placing the terminal
2-12 Chapter 2: Installing the system 98-129218-B
2.4 Placing the terminal
2.4.1 Where to place the terminal
Temperature conditions
The terminal must be placed in a ventilated area with free space around all sides of the unit,
except the bottom side.
Ambient temperature range is –25 °C to +55 °C.
If the terminal is installed in a location where the ambient temperature may exceed 45 °C,
we recommend placing the terminal where unintentional contact is avoided. If the
maximum ambient temperature does not exceed 45 °C, the terminal can be placed in a
public area.
Grounding access
The terminal is designed with a case for bulkhead or desktop installation. The case is
equipped with mounting brackets, making it possible to secure the unit on a bulkhead.
Important
The terminal must be placed in an area where access to the hull or equivalent
grounding can be reached within 0.5 m.

2.5.1 Grounding the terminal
Antenna cable
The antenna is connected to the terminal by means of a coax cable with a TNC connector
at both ends.
For information on antenna grounding, see Antenna grounding on page 2-9.
Ground stud
To ensure that the terminal is grounded – also if the cable is disconnected from the
terminal, connect an extra ground wire to the ground stud on the terminal. This ground wire
must be a heavy wire or braid cable with a larger diameter than the coax cable. The ground
stud is located next to the power switch.
