Planning the Installation
Figure 7. Elevation Limit of Obstacle
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 the radar especially on the same plane as its energy
levels may overload the antenna's front-end circuits. It is recommended to position
the antenna at least 4 feet (1.2 m) above or below the level of the radar and minimum
of 15 feet (4.6 m) away from any high power short wave radars.
The mounting platform should be rigid enough and not subjected to excessive
vibration. The movement of the antenna can be minimized by installing at the
center of the vessel. If these conditions can be only partially satisfied, choose the
best installtion site between various considerations that can satisfy the mentioned
conditions.
