1. Introduction
1.1. General Description of system
This shipboard TeleVision Receive Only (TVRO) system provides you with maritime DIRECTV® satellite
programming while you are inport or underway. Your DTV04 HD Antenna system will automatically locate
and receive signals of adequately high E.I.R.P. levels (see the Specifications section of this manual), in
circular polarization mode from 5 geosynchronous DIRECTV satellites in both Ku-band and Ka-Band
simultaneously. This input will be distributed to all of your satellite TV receivers which will provide the
Audio/Video to your televisions.
The DTV04 HD 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, the equipment essentially permits unattended operation.
The DTV04 HD system consists of two major groups of equipment; an above-decks group and a below-
decks group. Each group is comprised of the items shown, and listed, below. All equipment comprising the
Above Decks is incorporated inside the radome assembly and is integrated into a single operational entity.
In addition to the provided equipment this system requires an unobstructed line-of-sight view to the
satellites, ships Gyro Compass input and AC electrical power. The IF signals from the antenna are
distributed to the satellite receivers by the matrix switch. Video and Audio outputs from your satellite
receivers are available for distribution and monitoring.
