8 Raymarine 37STV Satellite TV System
Planning the installation
When choosing a location for the antenna, consider the following
points:
• Make sure you place it where there is an all round clear
view of the horizon.
• It should not be too high above the water – the maximum
recommended height is one not exceeding half the length of
your boat.
• It should be as near to the centreline of the boat as
possible.
• The mounting platform should be rigid and not subject to
excessive vibration.
• It should be away from the edge of the boat – this will avoid
unnecessary motion which can affect reception.
It should be clear of any
radar as this may prevent
the antenna working
correctly.
Make sure nearby objects do not
block the antenna. It requires a
+15
o
to +90
o
look angle to receive
satellite signals.
Cables
You need to consider the following
points before installing the system cables:
• All cables need to be adequately clamped and protected
from physical damage and exposure to heat – avoid running
cables through bilges, doorways, or close to moving
objects.
• Acute bends must be avoided.
• Where a cable passes through an exposed bulkhead or
deckhead, a watertight gland or swan neck tube should be
used.
Power Requirements
You need to consider the following power requirements:
• Your Raymarine Satellite TV system has been designed to
work on a boat’s power supply rated at 12 V DC.
• If your boat’s power supply is rated at 24 V DC you will need
to install a suitable DC power inverter to reduce the supply
voltage to 12 V DC.
• If your IRD(s) and television(s) require a 220/240 V AC
power supply, you will need to install a suitable DC to AC
converter to operate the units from your boat’s DC power
supply.
