Raymarine Satellite TV Antenna Systems

Planning the Installation
Selection of Installation Site
The antenna should be installed in a place where it has
an all-round clear view of the horizon. Ensure there are
no obstacles within 15 degrees above the antenna. Any
obstacles can prevent the antenna from tracking the
satellite’s signal (Refer to the drawing on the right).
Do not install the antenna nearby the radar, especially
if they’re on the same plane, as their energy levels may
overload the antenna’s 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 (4.6m) away
from any 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 it at the center of
the vessel. For optimal performance of the antenna, it is not
recommended to install it 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 it
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.
