14400MK2-21 C/Ku-Band TVRO Introduction
1-1
1. Introduction
1.1. General Description of system
Your Series 00 system is a fully stabilized antenna that has been designed and manufactured so as to be inherently
reliable, easy to maintain, and simple to operate. Except for start-ups, or when changing to operate with different
transponders or satellites, the equipment essentially permits unattended operation.
1.2. Purpose
This shipboard Television Receive Only (TVRO) system provides you with satellite TV programming while inport or
underway. Your Antenna system will receive signals of adequately high E.I.R.P. levels (see the Specifications section of
this manual), in linear or circular polarization mode from any of the geosynchronous TV satellites at C-Band or Ku-band
frequencies (dependant upon currently installed feed assembly). This input will be distributed to all of your satellite TV
receivers which will provide the Audio/Video to your Televisions. Many satellites also provide CD quality audio
programming which may also be routed to your stereo equipment.
1.3. System Components
Your TVRO Antenna 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.
Video and Audio outputs from your satellite receivers are available for distribution and monitoring.
For more information about these components, refer to the Basic System Information section of this manual.

1.4. General scope of this manual
This manual describes the Sea Tel Antenna (also called the Above Decks Equipment), its’ operation and installation.
Refer to the manual provided with your Antenna Control Unit for its’ installation and operating instructions.
1.5. Quick Overview of contents
The information in this manual is organized into chapters. Operation, basic system information, installation, setup,
functional testing, maintenance, specifications and drawings relating to this Antenna are all contained in this manual

14400MK2-21 C/Ku-Band TVRO Operation
2-1
2. Operation
2.1. System Power-up
Turn the Power switch on the louvered panel of the antenna pedestal ON. This will energize the antenna pedestal and
the associated RF equipment.
Turn the Antenna Control Unit (ACU) Power switch ON.
2.2. Antenna Initialization
A functional operation check can be made on the antenna stabilization system by observing its behavior during the 4
phases of initialization.
Turn the pedestal power supply ON. The PCU will initialize the stabilized portion of the mass to be level with the
horizon and at a prescribed Azimuth and Elevation angles. The antenna will go through the specific sequence of steps
(listed below) to initialize the antenna. These phases initialize the level cage, elevation, cross-level and azimuth to
predetermined starting positions.
Initialization is completed in the following phases, each phase must complete properly for the antenna to operate
properly (post-initialization).
1. Level Cage is driven CCW, issuing extra steps to assure that the cage is all the way to the mechanical stop.
Then the Level cage will be driven exactly 45.0 degrees CW.
2. Elevation axis activates - Input from the LV axis of the tilt sensor is used to drive the Elevation of the
equipment frame to bring the tilt sensor LV axis to level (this results in the dish being at an elevation angle of
45.0 degrees).
3. Cross-Level axis activates - Input from the CL axis of the tilt sensor is used to drive Cross-Level of the
equipment frame to bring the cross-level axis of the tilt sensor to level (this results in the tilt of the Cross-
Level Beam being level).
4. Azimuth axis activates -Antenna drives in azimuth until the “Home Flag” signal is produced. This signal is
produced by a Home Switch hitting a cam or by a Hall Effect sensor in close proximity to a Magnet.
This completes the phases of initialization. At this time the antenna elevation should 45.0 degrees and Relative
azimuth should be at be at home flag (home switch engaged on the home flag cam).
If any of theses steps fail, or the Antenna Control Unit reports model number as "xx97" re-configure the PCU as
described in section the Setup section of this manual. If initialization still fails, refer to the troubleshooting section of
this manual.
2.3. Antenna Stabilization
After initialization has completed, real-time stabilization of the antenna is an automatic function of the PCU.
2.4. Stabilized Pedestal Assembly Operation
Operation of the stabilized antenna Pedestal Control Unit (PCU) is accomplished remotely by the Antenna Control Unit
(ACU). Refer to the Operation section of the Antenna Control Unit manual for more specific operation details. There
are no other operating instructions applicable to the pedestal assembly by itself.
2.5. Tracking Operation
Tracking optimizes the antenna pointing, in very fine step increments, to maximize the level of the satellite signal
being received. The mode of tracking used in this antenna is a variation of Conical Scanning called DishScan®.
DishScan® continuously drives the antenna in a very small circular pattern at 60 RPM. The ACU evaluates the received
signal throughout each rotation to determine where the strongest signal level is (Up, Right, Down or Left) and issues
the appropriate Azimuth and/or Elevation steps to the antenna, as needed.
You cannot control tracking from the pedestal itself. Refer to the ACU manual for tracking operation information.
2.6. Antenna Polarization Operation
Linear feeds are equipped with a polarization motor and potentiometer feedback and are controlled from the Antenna
Control Unit. Auto-Polarization mode is the default polarization mode of operation from the ACU. Polarization may

Operation 14400MK2-21 C/Ku-Band TVRO
2-2
be operated manually from the ACU for diagnostic or alignment purposes. Refer to the Antenna Control Unit manual
for more operation information.
2.7. Low Noise Block Converter Operation
There are no operating instructions or controls applicable to the LNB. This unit is energized whenever the matrix
switch and satellite receiver(s) have AC power connected to them.
Satellite signals are either circular polarized (spiraling plane down from the satellite) or linear polarized (fixed plane
down from the satellite). The pedestal will receive circular polarization signals when a circular LNB is installed on the
back of the dish. Conversely, the pedestal will only receive linear polarized signals when a linear LNB is installed.
2.8. Radome Assembly Operation
When operating the system it is necessary that the radome access hatch (and/or side door) be closed and secured in
place at all times. This prevents rain, salt water and wind from entering the radome. Water and excessive
condensation promote rust & corrosion of the antenna pedestal. Wind gusts will disturb the antenna pointing.
There are no other operating instructions applicable to the radome assembly by itself.

3. Installation
This section contains instructions for unpacking, final assembly and installation of the equipment. It is highly recommended
that final assembly and installation of the Antenna system be performed by trained technicians. Read this
complete section before starting.
3.1. General Cautions & Warnings
WARNING: Assure that all nut & bolt assemblies are tightened according the tightening
torque values listed below:
Bolt Size Inch Pounds
1/4-20 75
5/l6-18 132
3/8-16 236
1/2-13 517
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: 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 the antenna assembly is being hoisted to its
assigned location aboard ship.
WARNING: Electrical Hazard – Dangerous AC Voltages exist inside the Antenna Pedestal
Breaker Box. Observe proper safety precautions when working inside the Pedestal Breaker Box.
WARNING: Electrical Hazard – Dangerous AC Voltages exists on the side of the Antenna

3.2. 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.
3.3. Preparing For The Installation
3.3.1. Unpack Shipping Crates
Exercise caution when unpacking the equipment.
3.3.2. Inspect / Inventory
Carefully inspect the radome panel surfaces for evidence of shipping damage. Inspect the pedestal assembly
and reflector for signs of shipping damage.
3.3.3. Prepare ADE Mounting Location
Prepare the mounting location for the Radome. If the radome is to be bolted to the deck (or a platform)
assure that the mounting holes have been drilled. Assure that the mounting hardware has been obtained and
is readily available.
3.3.4. Preparing BDE Location
Prepare the mounting location for the Below Decks Equipment. These equipments would normally be
installed in a standard 19” equipment rack. Refer to the Antenna Control Unit manual for installation of the
ACU and the Terminal Mounting Strip.

14400MK2-21 C/Ku-Band TVRO Installation
3-3
Refer to the vendor supplied manuals for installation of the other below decks equipments.
Prepare other locations throughout ship for any other equipment which is not co-located with the ACU.
3.3.5. Installing The System Cables
Install appropriate cables from Below Decks Equipment to the ADE Location(s).
The cables must be routed from the above-decks equipment group through the deck and through various ship
spaces to the vicinity of the below-decks equipment group. When pulling the cables in place, avoid the use of
excessive force. Exercise caution during the cable installation to assure that the cables are not severely bent
(proper bend radius), kinked or twisted and that connectors are not damaged.
Assure that the cables have been run through watertight fittings and/or will not permit water entry into the
ship when the installation is completed. After cables have been routed and adjusted for correct cable length
at each end, seal the deck penetration glands and tie the cables securely in place.
3.4. Assembling the ADE
The assembly procedure described below begins by sub-assembling sections of the baseframe, radome and pedestal.
Then these are assembled to form the ADE.
3.4.1. Preparing for Assembly of the ADE
Read this entire assembly procedure before beginning.
Refer to the System Block diagram, General Assembly, Baseframe Assembly, Radome Assembly and Radome
Installation Arrangement drawings for your system.
Select a secure assembly site that provides enough area to work with the large radome panels while sub-
assembling the baseframe, sections of the radome, Antenna Pedestal and Reflector & Feed. The area should
be a clean, flat location, free of rocks & debris (ie concrete). The site should also provide protection from
wind, rain and other adverse weather. A hoist, or small crane, is needed to assemble these sub-assemblies to
form the final ADE Assembly.
As an example, you might sub-assemble everything on the pier where the ship will tie up, then use the crane
to put the sub-assemblies together and lift the whole ADE up to the mounting location on the ship.
You can change order of these steps, however, in the end the objective is to have a well sealed
radome with flanges that are clean of excess caulking. In addition it is important that the ADE is
structurally sound for severe weather conditions.
3.4.2. Sub-assemble the Base Frame Assembly
Refer to the Base Frame Assembly drawing for your system and the procedure below.
NOTE: Unless otherwise indicated, all nuts and bolts should be assembled
with Loctite 2760 or its equivalent.
1. Assemble the two halves of
the base frame using the
splice plates and hardware
provided. Apply Loctite and
tighten hardware to specified
torque.

Installation 14400MK2-21 C/Ku-Band TVRO

2. Place the radome base frame
on temporary support blocks,
or jack stands, at least 10
inches high.
3. Bolt the eight 6 inch feet to
the under side of the radome
base frame using the
hardware provided. Loosely
assemble all feet before
tightening any of the bolts
and apply Loctite.
Temporarily remove the
support blocks, or jacks, and
set the base frame down on
the assembly surface to align
the feet. Tighten all the
hardware to specified torque.
Raise the base frame back up
onto the support blocks or
jacks.
4. Place the two base pan pieces
on the base frame. Install the
mounting hardware in the
four pan mounting holes.
5. Align the base pan perimeter
holes to the mounting holes
in the base frame. Note: You
may want to temporarily
insert bolts in 8-12
equidistant holes around the
perimeter of the base pans to
provide good alignment
throughout the perimeter
hole pattern.
6. Apply Loctite to the mounting
hardware and tighten. If
alignment bolts were inserted
around the perimeter in the
previous step, remove them
now.

7. Apply a good 3/8 inch bead of
silicon sealant to seal the
centerline of the two adjoined
halves of the base pan to keep
wind, water and dirt from
getting into the radome from
underneath.
8. Install the Base Hatch and
clamp the latches from the
under-side.
3.4.3. Sub-assemble the 168” Radome Assembly
Refer to the Radome Assembly drawing for your system and the procedure below. It is best to have at least
TWO people sub-assembling the radome, one working from the inside and the other outside. Sub-assemble
the sections of the radome on a clean, flat location that is free of rocks & debris (ie concrete) to assure a
horizontal alignment of the panels.
NOTE: Unless otherwise indicated, all nuts and bolts should be assembled
with Loctite 242 or its equivalent.

1. Loosely assemble the 8 riser
panels using the hardware
provided. Do NOT tighten the
bolts at this time. You may
want to set this sub-assembly
on the base pan to provide
good horizontal alignment of
the panels. Good alignment
of the bottom edge of the
panels is important for good
seal on the base pan.
2. To provide a clean caulked
seam all around the panels:
apply painters masking tape
to the outside perimeter of
each of the panels about ¼ “
from the top, bottom, left and
right edges at each flange
joint. The tape will be
removed just before the
radome caulking has had time
to set. Messy, smeared,
caulking will make the outside
of the radome look bad.
3. Open each vertical seam wide
enough to install a good bead
of silicone caulk, apply loctite
to and then firmly tighten all
of the bolts in that seam
(Smaller beads of caulking can
be applied from outside and
inside if you prefer).
4. Clean excess caulking off of
the flange area (inside and
out) as shown in step 11
below.

5. Repeat caulking, closing and
cleaning the vertical flanges
until all of the riser panel
seams are closed.
6. Remove the tape from the
vertical seams.
7. The riser section of the
radome is now complete.
8. On a flat surface, loosely
assemble the 8 lower panels
using the hardware provided.
Do NOT tighten the bolts at
this time. Assure good
horizontal alignment of the
panels. Good alignment of
the bottom edge of the
panels is important for good
seal on the riser panels and
good alignment of the top
provides a good seal between
the lower and upper panels.
9. To provide a clean caulked
seam all around the panels:
apply painters masking tape
to the outside perimeter of
each of the panels about ¼ “
from the top, bottom, left and
right edges at each flange
joint. The tape will be
removed just before the
radome caulking has had time
to set.

10. Open each seam wide enough
to install a good bead of
silicone caulk, apply loctite to
and then firmly tighten all of
the bolts in that seam (Smaller
beads of caulking can be
applied from outside and
inside if you prefer).
11. Clean excess caulking off of
the flange area (inside and
out). The empty Caulking
tubes can be used to clean
the excess caulking off
without scratching the
radome finish.
12. Repeat caulking, closing and
cleaning the vertical flanges
until all of the lower panel
seams are closed.
13. Remove the tape from the
vertical seams.
14. The lower section of the
radome is now complete.
15. Place short pieces of 2”x4”
boards under the perimeter of
the lower panel assembly to
raise it up off of the ground.
