Correct installation is required to ensure that EMC performance is
not compromised.
For optimum EMC performance we recommend that wherever
possible:
• Raymarine equipment and cables connected to it are:
– At least1m(3ft)from any equipment transmitting or cables
carrying radio signals e.g. VHF radios, cables and antennas.
STV unit is configured to receive either Linear or Circular polarized
modification to your STV system.

In the case of SSB radios, the distance should be increased
to7ft(2m).
– More than 2 m (7 ft) from the path of a radar beam. A radar
beam can normally be assumed to spread 20 degrees above
and below the radiating element.
• The product is supplied from a separate battery from that used
for engine start. This is important to prevent erratic behavior
and data loss which can occur if the engine start does not have
a separate battery.
• Cables are not cut or extended, unless doing so is detailed in
the installation manual.
Note: Where constraints on the installation prevent any of
the above recommendations, always ensure the maximum
possible separation between dierent items of electrical
equipment, to provide the best conditions for EMC performance
throughout the installation

Introduction to Raymarine STV
Raymarine STV37 / STV45 is a digital satellite antenna system
designed specifically for all types of vessels (anchored or transit)
to automatically identify, track and capture satellite signals from
the Digital Video Broadcasting (DVB: the international standard for
digital TV transmissions) compatible satellites.
In details, Raymarine STV37 / STV45 has Wide Range Search (WRS)
algorithm, which minimizes the search time during initialization, and
Dynamic Beam Tilting (DBT) technology, which dynamically shapes
the antenna beam to utilize stabilization. While tracking the target
satellite, DBT technology uses a high-performance, constantly
adjusting sub-reflector which allows the antenna to remain relatively
still, eliminating the constant whine of stepper motors while staying
locked on to the satellites.
The STV37 / STV45 has a built-in GPS system which enhances the
speed of satellite signals acquisitions. In addition, the “Auto Skew”
variant of the STV45 provides the embedded auto skew angle
control system to maintain the optimal signal strength and increase
the quality of satellite receptions in weak satellite single coverage
area.
Introduction

Raymarine Satellite TV Antenna Systems Introduction
Features of Raymarine STV37 / STV45
Enjoy satellite broadcasts at sea
Raymarine STV37 / STV45 is the most modern antenna
system that enables you to receive a high quality
broadcasting signal at sea, where the atmospheric and
environmental condition are very harsh. This fully automatic
control system allows you to simply turn the power switch
on, and have crystal clear, high quality satellite television in
motion or at anchor.
High quality antenna
High tech parabolic antenna technology has been adopted
for this antenna system, which is optimal for marine
conditions. This enables you to receive the optimal signal
level even when it is raining or snowing.
Fast and ecient search for the satellite
The WRS (Wide Range Search) algorithm allows for the
antenna system to search the satellite within the shortest
amount of time and to detect the satellite signal under any
position and with any directional movement of the vessel.
Easy installation and outstanding reliability
Raymarine STV37 / STV45 uses only one RF cable for
installation. This makes installation easy. Power, RF and
data signals transfer from the antenna to the ACU through
this single cable. In addition, Raymarine STV37 / STV45
provides highly reliable system through the implementation
of a modularized design, and the usage of strictly proven
components.
Built-in GPS
The built-in GPS system enhances the speed of acquisition
of the satellite signal and provides Raymarine STV37 / STV45
even higher performance.
Ethernet Port for management
The Ethernet Port on the rear panel of the ACU enables
direct and simple network connection between a PC and
the ACU. By connecting to ISP or the modem linked with
VSAT systems, Raymarine STV37 / STV45 can be monitored,
controlled, and diagnosed remotely from anywhere,
anytime through the TCP/IP protocol. This not only can save
tremendous time but also save the cost generated from the
hundreds of routine maintenance activities such as operating
firmware upgrades, tracking parameters resets, and system
diagnostic.
Wireless Connectivity and Aptus mobile
The built-in WiFi enables the ACU to be wirelessly
connected. Any kind of wireless devices such as PCs,
laptops and smartphones can be used to connect to the ACU
and monitor, control and change the settings of the system
wirelessly. The Aptus mobile app is available for download
to access the ACU via Wi-Fi and operate the antenna from
iPhone, iPad or other network devices. iPhone and iPad are
registered trademarks of Apple Inc.
Built-in automatic skew angle control system (STV45 Only)
The automatic skew control system allows Raymarine STV45
to maintain the optimal skew angle at all times and ensure
maximum level of satellite signal level receptions.
Raymarine’s environmental test standards certified
These standards are much severer than a typical
experienced marine equipment condition. All testes
performed with one unit through all continued sequences.
Raymarine standards meet LR and DNV standards as
well as EN60945.

Raymarine Satellite TV Antenna Systems
Planning the Installation
Antenna Unit
Install the antenna in accordance with the following
procedures to ensure maximum performance of the antenna.
The antenna should be installed in a place where it has an
all-around clear view of the horizon. Please be sure there
are no obstacles within 15 degrees above the antenna. Any
obstacles can prevent the antenna from tracking the satellite
signal (Refer to the drawing on the right).
Do not install the antenna near the radar especially on the
same plane, as their energy levels may overload the antenna
front-end circuits. It is recommended to position the antenna
at least 4 feet (1.2m) above or below the level of the radar
and a minimum of 15 feet (6m) away from the high power
short-wave radars.
The mounting platform should be suitably rigid and not
subjected to excessive vibration. The movement of the
antenna can be minimized by installing at the center of the
vessel. For optimal performance of the antenna, it is not
recommended to install at any corner of the vessel, where
the movement of the vessel is the greatest. Install the bottom
of the antenna parallel to the surface of the sea and fix tightly
to the structure of the vessel. When setting the antenna
down, be careful not to damage the RF connector. Striking
the connectors on the bottom directly will damage the
connector.
Figure 07 : Elevation Limit of Obstacles
15°

Cables
Before installing the system cables, consider the following
points.
• All cables need to be well clamped and protected from
physical damage and exposure to heat and humidity.
• Cables with severe bends are not allowed.
• Where a cable passes through an exposed bulkhead or
deckhead, a watertight grommet or swan neck tube should
be used.
Power Requirements
Follow the power requirements to avoid damage to the
system. The Raymarine STV37 / STV45 has been designed
to work on a boat’s power supply rated from 9 ~ 30 V DC.
If your receiver(s) and television(s) require a 110V/240V AC
power supply, you will need to install a suitable DC to AC
converter to operate the unit(s) from your boat’s DC power
supply.
RF Cable
This cable is supplied at a length of 49ft (15m). If a longer
length is required you should replace this cable with an
extended RF cable, available separately.
Extending the Cables
The cables that have been supplied with your Raymarine
system should be of adequate length to complete the
installation on most vessels.
Note: Exceeding the indicated cable lengths will result in
reduced performance of your system.

Installation and Mounting of Antenna
The method of installation and mounting of the antenna may
vary due to vessel design but the following procedures are
applicable in most situations, and will result in a secure and
eective installation.
Confirmation of Size Prior to Installation
• Check the height and diameter of the bottom surface of the
antenna before installing.
• The space must be sucient for installing the antenna unit
considering the height and diameter of the antenna.
• The height and the diameter of the bottom surface of the
antenna are as shown in the following drawings. If possible,
install the antenna using a “power tower”.
Note: Before installing the antenna, open the radome and
remove the shipping constraints from the antenna interior.

Marking the Antenna Mounting Position
Referring to the mounting template, mark where the antenna
will be mounted on board (it must be a flat surface) or on a
separate “power tower”.
Note: If a “power tower” is not suitable to mount the antenna,
separate cable shock and waterproofing measures must be
taken to protect the RF connector from being exposed to the
sea water and external shocks. An exposed cable may cause
electric shock and cause serious damage to the equipment.

Raymarine Satellite TV Antenna Systems
Securing Holes for Bolts and Cable Ways
Make 4 bolt holes of 10mm diameter, one at each corner of a
rectangle drawn as below, and make a circular hole of 80mm
diameter at the center of the rectangle through which the
cable will run.
Connection of the Cable
Remove the rubber cap from RF connector. Connect the RF
cable to the RF connector under the base plate through the
access hole using an 11mm spanner. Be careful not to over
tighten, as you may damage the connector.
