ST24 Ku-Band TVRO Quick Start
2-1
2. Quick Start
Operation of the ST24 Series antenna is accomplished via the Graphic Antenna Control Panel (GACP). Once properly
configured, the antenna will automatically search for and identify the last targeted satellite held in memory. Because of
programming requirements or changing of geographic locations, you may be required to change what satellite you wish to
track.. Read below for general panel operation instructions.
2.1. General Panel Operation
The GACP is a Panel Mount touch screen controller and navigation through its main and sub menu’s is accomplished
by pressing the desired icon itself and not the descriptive text below the icon. When applicable, the Left and Right
arrows may be used to navigate between main menu pages. The HOME icon may be pressed to return to the HOME
Page from any given menu or sub menu display. The Panel will go into a locked mode after five minutes of inactivity.
The Panel will go into Sleep mode after being in a locked mode for five minutes. NOTE: The Antenna will still be fully
functional. Press anywhere on the screen to bring the panel out of sleep mode and access the “Panel Unlock” screen.
The graphic to the right depicts the proper way to navigate through the menus by pressing
the icon itself.
The graphic to the right depicts the incorrect way to navigate through the menus by
pressing on the displayed text.

3. Installation
Installation of the ST24 Antenna system will be presented into two major sections, the Above Decks Equipment (ADE) and the
Below Decks Equipment (BDE). This installation must be performed by or under the direct supervision of an authorized Sea Tel
Dealer for the limited warranty policy to be valid and enforced. A proper Site Survey MUST be performed prior to the actual
antenna installation to help ensure the best possible operation of the system. Proper planning is the key to a good installation,
please read this entire chapter thoroughly before beginning the actual installation and measure it against your site survey and
make adjust any details that you may have been overlooked.
The three following Simplified Block Diagrams (figures 1-3) are for visual reference only. Always refer to the System Block
Diagram, located in the drawings section of this manual for Coax and Wire interconnections and/or troubleshooting purposes.

3.1. Verify System Components
Before beginning it is critical that you inventory all system components. Refer to the appropriate packing list for your
Model antenna. Any discrepancies should be immediately reported to the Sea Tel service department so that a Service
Call may be filed and the required parts be shipped out.
3.2. Site Selection
Determine the optimum mounting location for the antenna radome assembly. Choosing the best mounting location
on vessels where there are few choice locations to choose from, is frequently a compromise. Below are some
considerations that should be taken as part of the Site Survey process.
•Above Decks
1. Blockage: The antenna should be mounted where the antenna has a clear line-of-sight view to as much of
the sky as is practical. Choosing a location where masts or other structures do not block the satellite signal
from the dish as the boat turns will directly affect the antenna’s ability to locate and track the desired
satellite.
2. The antenna is at least 5 feet away from other transmitting antennas (HF, VHF and radar) that may generate
signals that may interfere with the Coastal Series antenna. The further away the Coastal antenna is from
these other antennas, the less impact their operation will have on it as will our antenna have less of an impact
on them.
3. The antenna radome assembly should be rigidly mounted to the boat. If necessary, reinforce the mounting
area to assure that it does not flex due to the boat motion or vibration.
4. Bow or the Stern? Due to the violent G-forces exerted onto an antenna while the vessel’s BOW heaves versus
the relatively “cushioned” G-forces exerted onto an antenna at the stern of the vessel choosing the Stern
would be the ‘best’ option with all other factors being equal.

Installation ST24 Ku-Band TVRO

5. Mounting Height: The pedestal mounting height specification is not intended to be an absolute restriction on
pedestal placement. It is generically referred to in the section of the manual which describes the vessel
motions for which the stabilization accuracy is guaranteed. An exact mounting height limit is difficult to
quantify since all vessels respond differently to various wave patterns and no two sea-states produce the
same pattern of waves. We can, however, state a range of practical conditions and show the expected
pedestal response and limits for those conditions. Figure 2-2 shows the expected antenna performance in
relationship to vessel motion.
Figure 3-2 Antenna Mounting Height vs. Antenna Performance
6. Below Decks Equipment. Knowing where the BDE will be installed is useful so that you can determine the
shortest and most convenient cable path from the antenna to below decks.
•Below Decks
The Graphic Antenna Control Panel should be mounted in a convenient location for the operation of the
antenna system. It should be near one of the satellite receiver/television locations so that the receivers’ TV
screen can be viewed while the antenna is being operated. The supplied antenna control cable is routed from
the radome to the control panel, so routing path and cable length are important considerations both in
choosing the location of the control panel and to determine what type of RF cable should be used. The
technical specifications section of this manual provides the Sea Tel recommended cable type(s) as defined by
the overall cable run (from radome to the furthest receiver on the network).
Satellite receiver(s) and television set(s) - Satellite receiver(s) and television set(s) should be mounted near
each other in convenient viewing locations. If enclosed in a cabinet or panel, assure that there is adequate
airflow to prevent the receiver(s) and active matrix switch from over-heating and provide forced airflow if
needed. At each receiver location, leave a sufficient length of cable (service loop) to remove the receiver in
order to access its rear panel without pulling connections off of the rear panel.
3.2.1.
1. Lay the Installation Template (drawing 132903) on the mounting surface location that you have
chosen to mount the radome on.
Prepare the Antenna Radome Mounting Location
2. Align the radome “bow” mark on the template to be parallel to the bow of the boat. By default the
orientation of the “Sea Tel” logo is oriented towards BOW. You may as you see fit, adjust the
position of the “Bow” marker on template to orient the LOGO where you want it. When you are
satisfied with the position, tape the template in place.

3. Using the center punch and hammer, mark the locations of the four radome mounting holes and the
cable passage. Remove the template drawing.
The 29” radome assembly provides the means to install the antenna to its
mounting surface on either a 9” D.B.C (factory default) or 12” D.B.C. You are only
required to use one of these hole patterns, not both.
4. Drill the four radome mounting holes using the 7/16” drill bit and the cable passage hole using a 4.5”
hole saw.
3.2.2.
1. Lay the Installation Template (drawing 132230) on the mounting surface location that you have
chosen to mount the Graphic Antenna Control Panel in.
Prepare the Antenna Control Panel mounting location
2. Adjust the position of the template to center the Antenna Control Panel cutout portion of the
drawing where you want it. When you are satisfied with the position tape the template in place.
3. Using the center punch and hammer, mark the locations of the four mounting holes and the four
corners of the cutout area. Remove the template drawing.
4. Mark the perimeter of the cutout area. Drill a hole inside the perimeter of the cutout area to enable
you to cut the area out with the saw (the 1” hole saw might be used for this).
5. Cut the area out.
6. Drill out the four GACP mounting holes.
3.3. Cable and Equipment Installation
Using the Matrix list below, determine the System Block Diagram (SBD) document number for your model antenna
system. This SBD will be utilized for component interconnection information.

3.3.1.
In addition to the required Coaxial cable that will interconnect the above decks equipment with the below decks
equipment, you will need to determine what cables are going to be used to interconnect satellite receivers to the
televisions and if installed the surround sound system. The below guide may be used to help determine which cable
type is best suited for your installation. You should refer to the manual of the CFE equipment for additional guidance.
Determine your Cables
Video Connection Reference Audio Connection Reference:
OK: Composite Video (Non-HD Video Only)
Typically an RCA Jack, this type
of connection combines and
transmits chrominance and
luminance information on a
single cable.
OK: Stereo RCA (2 channel Analog)
These RCA Jack connections are a means of
passing analog line-level audio signals (split
into left and right channels) from the
satellite receiver to your television or audio
amplifier.
Good: S-Video (Non HD Video Only)
S-video connections transmit
the chrominance (color) and
luminance (brightness) portions
of a video signal along different
paths, allowing them to be
processed separately.
Good: RCA (Multi-Channel Analog)
These preamp-level analog inputs
features jacks for up to 8 channels:
left front, right front, center channel,
left surround, right surround, and
subwoofer. Because the subwoofer
channel carries a limited range of frequencies, it's the
".1" in 5.1. A 6.1 input features the same jacks as a 5.1
input, but adds a back surround jack. A 7.1 input adds
two back surround jacks.
Better: Component (HD Video Only )
This 3-cable connection allows the
chrominance (color) and luminance
(brightness) portions of a video
signal to be processed separately
.S-Video works similarly, but
component video improves color
accuracy further by splitting the chrominance
signal into two portions.
Better: XLR (Hi Resolution Analog)
XLR audio
connections are
used primarily
with high-
performance audio gear. This 3 pin connector
dedicates one of these pins for ground which helps
reduce electronic noise throughout the cable. A clasp
built into the round XLR plug locks it tightly into the
socket, ensuring a secure connection even during full
ships motion.
Best: HDMI (Both HD Video and Digital Audio)
HDMI is a multi-pin connection used for passing standard- and high-definition
digital video signals, as well as up to 8 discrete digital audio channels, through a
single cable.
