Selecting the location
Determine the optimum mounting location for the antenna random assembly. It should
be installed where:
1. The antenna has a clear line-of-sight view to as much of the sky as is practical. Choose
a location where masts or other structures do not block the satellite signal from the dish
as the vessel turns.
2. The antenna is at least 5 feet away from other transmitting antennas (HF, VHF and
radar) that may generate signals that may interfere with the antenna. The further away
the antenna is from these other antennas, the less impact their operation will have on it.
If these conditions cannot be entirely satisfied, the site selection will inevitably be a "best"
compromise between the various considerations.
Perform a through site inspection on the roof for the antenna to be
mounted.
1.
The antenna must have a clear view of the sky and the horizon at all the
directions to avoid blockage of the satellite signal.
2.
The antenna should be on the top of the vehicle.

Equipment and cable installation
This offers a general explanation of how to install the IDU and satellite receiver properly
to the inside of vessel connecting with Main Cable and coaxial cable.
1.
The Coaxial cable and Main cable is routed from the antenna to the IDU inside the
vessel.
2.
After Once deciding where to place the IDU and satellite receiver, make sure that
both units are placed in a dry and protected area.
3.
The IDU and satellite receiver should be placed away from any heat source and in an
area with proper ventilation.
4.
Ensure that there are at least 3cm of space around both units for ventilation and
connection of cables. Do not stack the units on top of each other.
5.
The following describes the basic wiring configurations for the antenna system.
• Connect the Main Cable and Coaxial cable to the antenna port on the back of the
IDU.
• Connect one end of the supplied coaxial cable to the receiver port on the back of
the IDU.
• Connect the other end of the coaxial cable to the satellite receiver.
