ST88-21 C/Ku-Band TVRO Introduction
1-1
1. Introduction
1.1. General Description of system
Your 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 Television Receive Only (TVRO) system provides you with satellite TV programming while in port or
underway. Your Antenna system will receive signals of adequately high E.I.R.P. levels (see the Specifications section of
this manual), in linear or circular polarization mode from any of the geosynchronous TV satellites at C-Band or Ku-band
frequencies (dependent upon currently installed feed assembly). This input will be distributed to all of your satellite TV
receivers which will provide the Audio/Video to your Televisions. Many satellites also provide CD quality audio
programming which may also be routed to your stereo equipment.
1.3. System Components
Your TVRO Antenna 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.
Video and Audio outputs from your satellite receivers are available for distribution and monitoring.
For more information about these components, refer to the Basic System Information section of this manual.
