2.2 Antenna Installation
2.2.1 Select Location
Perform a through site inspection for the antenna to be mounted. There are
several factors to consider when choosing the location for the SATMAR45
antenna.
1. The antenna must have a clear view of the sky and horizon at all the
direction
to avoid blockage of the satellite signal.
2. Keep the antenna clear of any obstructions above decks. The antenna
requires a 10 to 80 degree look angle to receive satellite signals.
3. To minimize tracking errors, place the antenna unit as close as
possible to the intersection of the vessel’s fore-and aft centerline and
midships
4. Using two people, place the antenna onto the vessel platform. Do not
try to
install the antenna by yourself.
■ The mounting surface should be flat and strong enough to support
the complete assembly.
■ Make sure that the mounting surface is rigid.
2.2.2 Equipment and cable installation
This offers a general explanation of how to in stall th e Indoor Unit an d satellit e
receiver properly to the inside of vessel connecting with coax cable.
1. The RF cable is routed from the antenna to the IDU inside the vessel.
2. Once decide where to place the IDU and satellite receiver, and ma ke
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
SATMAR45 antenna system.
■ Connect the RF cable to the SATMAR45 port (antenna) on the back
of the IDU
■ Connect one end of the supplied coax cable to the receiver port on
the back of the IDU
■ Connect the other end of the coax cable to the satellite receiver in
the LNB INPUT
