CAUTION: 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. Prior to work on
the stabilized antenna system, the power to the transmit/receive system must be locked out and
tagged.
When the transmit/receive system is in operation, no one should be allowed anywhere within the radiated
beam being emitted from the reflector.
The ultimate responsibility for safety rests with the facility operator and the individuals who work
on the system.

1.4. General scope of this manual This manual describes the Sea Tel Series 06 Antenna (also called the Above Decks Equipment), its’ operation and installation. Refer to the manual provided with your Antenna Control Unit for its’ installation and operating instructions. - Page 10 2406-7 Broadband At Sea Introduction THIS PAGE INTENTIONALLY LEFT BLANK...

Page 11: Operation
Operation 2406-7 Broadband At Sea Operation Operation of your system is accomplished from the DAC-2202 Antenna Control Unit (ACU). Refer to the operation section of the DAC-2202 Antenna Control Unit manual. 2.1. System Power-up Turn the power switch on front panel of the Antenna Control Unit (ACU) and the breaker switch inside the Antenna Radome ON to energize both units. -
Page 12: Antenna Polarization Operation
2406-7 Broadband At Sea Operation DishScan continuously drives the antenna in a very small circular pattern at 60 RPM. The ACU evaluates the received signal throughout each rotation to determine where the strongest signal level is (Up, Right, Down or Left) and then issues the appropriate Azimuth and/or Elevation steps to move the antenna toward where stronger signal is. -
Page 13: Basic System Information
Basic System Information 2406-7 Broadband At Sea Basic System Information This section provides you with some basic information about your antenna system and other equipment within your system configuration. 3.1. Satellite Basics The satellites are in orbit at an altitude of 22,753.2 Statute Miles positioned directly above... -
Page 14: Signal Level
2406-7 Broadband At Sea Basic System Information 3.1.2. Signal level The level of the receive signal on a point on the globe is dependant upon how powerful the transmission is and how wide the signal beam is coverage area is. Focusing the signal into a narrower beam concentrates its energy over a smaller geographic area, thereby increasing the signal level throughout that area of coverage. -
Page 15: Elevation
3.2.6. Stabilization This Sea Tel antenna is 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 16: Tracking
2406-7 Broadband At Sea Basic System Information the satellite are saved to expedite future acquisition of the desired satellite. The system must have adequate satellite signal level to stop searching (and begin tracking the acquired satellite). 3.2.9. Tracking The ACU 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. -
Page 17: Above Decks Ac Power Supply
Basic System Information 2406-7 Broadband At Sea The Antenna Control Unit (ACU) communicates via an RS-422 full duplex data link with the Pedestal Control Unit (PCU) located on the antenna. This control signal to/from the antenna is on the Coax cable along with the L-Band Receive IF from the LNB. -

2406-7 Broadband At Sea Installation 4.4. Installing the Above-Decks Equipment (ADE) 4.4.1. 34” Radome Assembly The antenna pedestal is shipped completely assembled in its 34” radome. WARNING: Hoisting with other than a webbed four-part sling may result in catastrophic crushing of the radome. Refer to the specifications and drawings for the fully assembled weight of your model Antenna/Radome and assure that equipment used to lift/hoist this system is rated accordingly. -
Page 21: Cable Installation
Installation 2406-7 Broadband At Sea Remove the radome top to access the pedestal. Inspect the pedestal assembly and reflector for signs of shipping damage. 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. -

Page 24: Optimizing Auto-Polarization Tx/Rx
2406-7 Broadband At Sea Set-up & Configuration 5.4. Optimizing Auto-Polarization TX/RX This procedure optimizes the linear polarization of the feed, if your system is fitted with a circular feed you do not need to optimize the polarity angle and can skip this procedure. At the ACU, turn tracking and DishScan Drive off. - Page 25 Set-up & Configuration 2406-7 Broadband At Sea If Targeting has NOT been optimized, allow the antenna to initialize to its home flag position. Visually compare the antennas pointing to the bow-line of the ship (parallel to the Bow). Note the antennas position relative to the Bow.

Maintenance and Troubleshooting 2406-7 Broadband At Sea 7.3. Troubleshooting 7.3.1. Theory Of Stabilization Operation The antenna system is mounted on a three axis stabilization assembly that provides free motion with 3 degrees of freedom. This assembly allows the inertia of the antenna system to hold the antenna pointed motionless in inertial space while the ship rolls, pitches and yaws beneath the assembly. -
Page 34: Troubleshooting Using Dacremp
7.3.3. Troubleshooting using DacRemP While troubleshooting a Sea Tel 3-Axis Antenna System, you must classify the fault you are dealing with as a failure within one of 3 major system functions, Targeting, Stabilization, and Tracking. Should there be a failure with any one of these functions, your system will not operate properly. A few simple checks may help determine which fault (if any) that you are dealing with. -
