  • Page 7: Introduction

    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.

  • Page 8: General Scope Of This Manual

    1.2. General scope of this manual This manual describes the Sea Tel Model DTV04 HD Antenna (also called the Above Decks Equipment), its operation and installation. The Below Decks Equipment is described in the manuals provided with your DAC-2202 Antenna Control Unit 1.3.

  • Page 9: Operation

    DTV04 HD TVRO Antenna Operation Operation Operation of your system is accomplished from the Antenna Control Unit (ACU). Please refer to the operation section of the DAC-2202 Antenna Control Unit manual. 2.1. System Power-up Turn ON the power switch on the front panel of the ACU. The DTV 04 HD Antenna receives its DC power from the Antenna Control Unit (ACU) when the ACU is energized.

  • Page 10: Tracking Operation

    Tracking Operation The design of this system allows for simultaneous reception of 5 satellites, 3 at Ku-Band and 2 at Ka-Band. For the DTV04 HD Antenna system all tracking parameter entries are based on signal level received from 101°W. Tracking optimizes the antenna pointing, in very fine step increments, to maximize the level of the satellite signal being received.

  • Page 11: Basic System Information

    Your DTV04 HD antenna is designed to be used with DIRECTV Satellites that operate at both the Ku-Band (12.2-12.7GHz) and Ka-Band (18.3 – 18.8GHz and 19.7 – 20.2GHz) in this orbit that have a strong enough receive signal level in your location.
  • Page 12 Basic System Information DTV04 HD TVRO Antenna Blockage - Blockage is loss due to an object in the path of the signal from the satellite to the dish. If an object that is large and dense is positioned in the path of the signal from the satellite, it will prevent sufficient signal from arriving at the dish.

  • Page 13: Signal Level

    Satellites may transmit their signals in one of two different polarization modes, linear (like a flat ribbon down from the satellite) or circular (like a twisted ribbon spiraling down from the satellite). The DTV04 HD antennas are designed to receive circular satellite signals only. 3.2. Antenna Basics Figure 3-5 Satellite Signal Polarization The satellite dish is mounted on a three jointed pedestal.

  • Page 14: Antenna Reflector/Feed Assembly

    Stabilization Reflector/Feed Assembly The DTV04 HD antennas are stabilized in three axes of motion. Stabilization is the process of de- coupling the ships motion from the antenna. Simply put, this allows the antenna to remain pointed at the satellite while the boat turns, rolls or pitches under it. To accomplish this, the Pedestal Control Unit (PCU) on the antenna pedestal senses any motion of the antenna and immediately applies drive to the appropriate motor (s) to oppose the sensed motion.

  • Page 15: Tracking

    3.2.7. Tracking The DTV04 HD antenna actively optimizes the pointing of the dish for maximum signal reception. This process is called tracking and is accomplished by continuously making small movements of the dish while monitoring the level of the received signal from DIRECTV at 101°W. Evaluation of this information is used to continuously make minor pointing corrections to keep the signal level “peaked”...

    The DTV04 04 Antenna system is comprised of two major sections: The Above-Decks Equipment (ADE) is comprised solely of the DTV04 HD antenna radome assembly which is mounted outside, on the boats upper deck or mast location. The Below-Decks Equipment (BDE) includes the Antenna Control Unit, may include the optional Touch Screen Controller panel, satellite receiver(s), TV set(s) and all other ancillary equipment that is mounted in various locations throughout the interior of the boat.

    The following instructions describe the installation procedures for installing the Series 04 Antenna (ADE). 4.1. General Cautions & Warnings CAUTION - Allow only an authorized dealer to install or service the your Sea Tel Television Receive Only System components. Unauthorized installation or service can be dangerous and can invalidate the warranty.

Inspect the pedestal assembly and reflector for signs of shipping damage. 3. Remove the web strap shipping restraints from the pedestal. Save these straps to restrain the antenna in the event that the AC power will be turned off while the ship is underway.
