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.
