9711IMA-70 Introduction
1-1
1. Introduction
WARNING: RF Radiation Hazard - This stabilized antenna system is designed to be used with
transmit/receive equipment manufactured by others. Refer to the documentation supplied by the
manufacturer which will describe potential hazards, including exposure to RF radiation, associated with
the improper use of the transmit/receive equipment. Note that the transmit/receive equipment will
operate independently of the stabilized antenna system.
The ultimate responsibility for safety rests with the facility operator and the individuals who
work on the system.
1.1. General System Description
Your system includes a fully stabilized antenna that has been designed and manufactured so as to be inherently
reliable, easy to maintain, and simple to operate. The equipment essentially permits unattended operation except
for start-ups or when changing to different transponders, or satellites.
1.2. Purpose
This shipboard Transmit-Receive (TXRX) system provides you with two-way satellite voice/data broadband
communications while underway on an ocean-going vessel. This can be used to provide a wide variety of
telephone, fax and high speed data applications. Your antenna system can transmit to and receive from any
desired C-band satellite which has adequate signal coverage in your current geographic area. This input will be
distributed to your satellite modem and then to all of your other below decks computer, fax and telephone
equipment.
1.3. Other Inputs to the System
Multi-conductor cables from Ship’s Gyro Compass, GPS, phone, fax and computer equipment may be connected in
the system.
1.4. System Components
This TXRX system consists of two major groups of equipment: an above-decks group and a below-decks group.
Each group is comprised of, but is not limited to, the items listed below. All equipment comprising the Above
Decks is incorporated inside the radome assembly and is integrated into a single operational entity. For inputs, this
system requires only an unobstructed line-of-sight view to the satellite, Gyro Compass input and AC electrical
power.
For more information about these components, refer to the Basic System Information section of this manual.
