Antenna Unit
The antenna installation requires extreme precaution and safety measures given its size and weight. Failure
to follow the correct installation process may lead to injury of the installer and/or cause damage to the
system. In order to maximize the performance of the system, a thorough review of this installation guide is
strongly recommended, as well as executing the installation process as it is noted in this manual.
4.1 Selecting Installation Site
The system should be placed in an area onboard the vessel with little to no RF signal blockage. When the
antenna is transmitting, obstacles in way of the beam path will cause decreased satellite signal strength.
The antenna unit should have direct line-of-sight with the desired satellite without any obstacles in the
beam path. Certain minimum distances between the antenna and other onboard devices must also be
considered during installation.
4.1.1 Minimizing Satellite Blockage
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 with all around clearance.
Make sure there are no obstacles within the EL range -20° to +115° from the center of the antenna.
Obstacles can interrupt the satellite signal transmission and reception of the antenna.
