Site Survey Sea Tel TVHD Antenna Systems

1. 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.
1.1. 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.
1.2. Antenna Shadowing (Blockage)
Any substantial structures in the path between the front of the antenna and the satellite it is pointing to will cause
significant degradation of the signal. The location of the ADE should be chosen to minimize blockage caused by the
structures of the ship. It is desirable to be mounted high enough to minimize the effects of the surrounding structures
while not being mounted too high (refer to mounting height information below). Large, solid, structures will cause
significant signal loss while wire rope stays, lifelines, small diameter handrails and other accessories may cause little to
no noticeable loss.

Sea Tel TVHD Antenna Systems Site Survey

1.3. Mounting Foundation
1.3.1. 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.
1.3.2. 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.
1.3.3. 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)

Site Survey Sea Tel TVHD Antenna Systems
1-3
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.
1.4. 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.
1.5. 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:

Sea Tel TVHD Antenna Systems Site Survey
1-4
1.5.1. 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.
1.5.2. 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.
1.5.3. 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.

Site Survey Sea Tel TVHD Antenna Systems
1-5
1.5.4. 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.
1.6. 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 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.
1.7. Below Decks Equipment Location
The Antenna Control Unit (LMXP) is a standard 19” rack mount enclosure, therefore, preferred installation is in a
standard 19” equipment rack. The ACU mounts from the front of the rack.
The Satellite Receivers, multi-switch and any other associated equipment should be properly mounted for shipboard
use.
Plans to allow access to the rear of the ACU, and other equipment, should be considered.
1.8. 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.

Sea Tel TVHD Antenna Systems Site Survey
1-6
1.8.1. ADE/BDE Coaxial Cables
The first concern with the coaxial cables installed between the ADE & BDE is length. This length between the
ADE & BDE 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 receivers.
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 (refer to the cables bend radius specification). 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.
1.8.2. ACU Power Cable/Outlet
The AC power for the ACU and the ADE is not required to be from a UPS but it is recommended.
Power cable shall comply with the provisions of IEC 60092-350 and -351 in so far as practicable.
1.8.3. Gyro Compass Cable
Use good quality shielded cables (twisted pairs, individually foil wrapped, outer foil with braid overall is best).
You only need 2-wire for NMEA signal … always use shielded cable. Be cautious of length and gauge of the
run to minimize voltage loss issues.
1.9. Grounding
All metal parts of the ADE shall be grounded to bare metal that is common to the hull of the ship. This is most
commonly accomplished by attaching a ground wire/cable from the upper base plate ground point to a ground stud on
the mounting pedestal/stanchion/mast near the base of the radome. Preservation of the bare metal contact point
should be done to prevent loss of ground due to rust and/or corrosion.
Grounding by exposing bare metal under all mounting bolts of the under-side of the radome base prior to final
tightening does NOT provide adequate grounding of the ADE.
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.

2. Installation
Your antenna pedestal comes completely assembled in its radome. This section contains instructions for unpacking, final
assembling and installing of the equipment. It is highly recommended that trained technicians install the system.
The installation instructions for your system are below.
2.1. Unpacking and Inspection
Exercise caution when unpacking the equipment.
1. Unpack the crates. Carefully inspect the radome surface for evidence of shipping damage.
2. Unpack all the boxes.
3. Inspect everything to assure that all materials have been received and are in good condition.
2.2. Assembly Notes and Warnings
NOTE: All nuts and bolts should be assembled using the appropriate Loctite thread-locker
product number for the thread size of the hardware.
Loctite # Description
222 Low strength for small fasteners.
242 Medium strength
638 High strength for motor shafts & sprockets.
2760 Permanent strength for up to 1” diameter fasteners.
290 Wicking, High strength for fasteners which are already
assembled.
WARNING: Assure that all nut and bolt assemblies are tightened according to the
tightening torque values listed below:
SAE Bolt Size Inch Pounds Metric Bolt Size Kg-cm
1/4-20 75 M6 75.3
5/l6-18 132 M8 150
3/8-16 236 M10 270
1/2-13 517 M12 430
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 hoisting the antenna assembly to its
assigned location aboard ship.

2.3. Installing the ADE
The antenna pedestal is shipped completely assembled in its radome. Please
refer to the entire Site Survey chapter of this manual.
Base Hatch Access - Mounting the radome directly on the deck/
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) or lost.
If access to the hatch cannot be provided in the mounting surface, provide a
short ADE mounting stanchion 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.
Cable Passage - When strain relief glands are being used the
recommended cable passage will be in/out the starboard side of the base of
the radome approximately 12 inches from the center of the radome base,
down along the side if the pedestal, through the deck and into the interior of
the ship.
2.3.1. Prepare the 1.2M Radome Assembly
1. Remove the side walls of the radome crate.
2. Lift the pallet using a forklift and/or jacks.
3. From the underside of the pallet, remove the
four shipping bolts which attach the ADE to
its’ pallet. Discard this shipping hardware.
4. Holding the lifting bracket in place, remove
two original bolts from the correct locations
for where bolts will be installed in the bracket.
Keep the original perimeter bolt hardware to
be reinstalled after the ADE has been installed.
5. Install two bolts (provided in the radome
installation kit) through the bracket into the
radome top to mount one of the brackets.
6. Repeat step 4 & 5 to mount the other three
lifting brackets in equally spaced locations
around the perimeter of the radome flange.
7. Attach properly load rated four part web
lifting sling (or four individual straps) to the
brackets using shackles.
8. Attach a suitable length tagline to one of the
eyebolts.

9. After the ADE is hoisted into place the lifting
eyes are to be removed and replaced with the
original stainless hardware that was removed
in step 4.
2.3.2. Installing the 1.2M Radome Assembly
The antenna pedestal is shipped completely assembled in its radome.
1. Hoist the antenna assembly off the shipping pallet,
by means of a suitably sized crane or derrick, to
allow access to bottom of radome assembly.
2. Open the hatch by pressing the round release button
in the latches and gently push the hatch up into the
radome. Place the hatch door (gel coat surface up)
inside the radome on the far side of the antenna
pedestal.
3. Inspect the pedestal assembly and reflector for signs
of shipping damage.
4. Peel the paper off of the mounting pad (provided in
the radome installation kit) to expose the sticky side
of the pad, align it to the mounting holes and press
it in place on the underside of the radome base.
5. Using Loctite 271, install the four mounting studs
(provided in radome mounting kit) into the radome
base.
6. Man the tag line and have the crane continue lifting
the ADE up and hover above the mounting site on
the ship.
7. Carefully route the ground strap/cable (see
Grounding info below) and 5 power & IF coax cables
through the cable passage in the bottom center OR
the offset cable entry (as desired).
Center Cable Entry
