INSTALLING THE ANTENNA
Planning the Installation
Selection of Antenna Installation Site
Install the antenna in accordance with the following procedures to ensure maximum
performance of the antenna. The ideal antenna site should have a clear view of
the horizon or satellite all around it. Please be sure there are no obstacles within
15º above the center of the antenna. Any obstacles can prevent the antenna from
transmitting and receiving the satellite signal.
Do not install the antenna near by the radar especially on the same plane as the
microwave radar transmissions as these will 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 minimum of 15 feet (4.6m) away from any high power short
wave radars.
The mounting platform should be robust enough and not subject 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 on 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 x tightly to
the structure of the vessel.
