9707D-70 C-Band TXRX 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 Series 07 system is a fully stabilized antenna that has been designed and manufactured so as to be inherently
reliable, easy to maintain, and simple to operate. Except for start-ups, or when changing to operate with different
transponders or satellites, the equipment essentially permits unattended operation.
1.2. Purpose
This shipboard Transmit-Receive (TXRX) system provides you with two-way satellite voice/data communications while
underway on an ocean-going vessel. This can be used to provide a wide variety of telephone, fax and data
applications. Your Series 07 Antenna system can transmit to and receive from any desired satellite which has
adequate signal coverage in your current geographic area. Your antenna is fitted with appropriate Transmit & Receive
RF Equipment and appropriate Feed to allow you to operate in circular polarization mode at C-Band frequencies. This
input will be distributed to your satellite modem and then to all of your other below decks equipment.
1.3. System Components
The 9707 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.
A. Above-Decks Equipment (ADE) Group
1. Stabilized antenna pedestal
2. Antenna Reflector
3. Feed Assembly with LNB(s)
4. C-Band Block Up Converter (BUC)
5. Radome Assembly
B. Below-Decks Equipment Group
6. Antenna Control Unit
7. Splitter with desired number of outputs (one output to the ACU and one output to the Satellite Modem are
required).
8. Satellite Modem and other below decks equipment required for the desired communications purposes.
9. Spectrum Analyzer (Optional)
10. Control, RF and Video cables
