Direct Broadcast Satellite Overview

Direct Broadcast Service (DBS) satellites broadcast audio, video and data information from satellites located 22,000 miles in space. A receiving station, such as the Seaman antenna, should include a dish and satellite receiver to receive the signals and process them for use by the consumer audio and video equipment. The system requires a clear view of the satellite to maximize the signal reception.

Blocked

!

Figure 1-2 Satellite

Objects such as tall lighthouse, bridges and big ship that block this view will cause a loss of signal. The signal will be quickly restored once the antenna has a clear line of sight again. Heavy rain, cloud, snow or ice may also interfere with the signal reception quality. If the satellite signal is lost due to blockage or severe weather condition, services from the receiver will be lost (picture will freeze frame and may disappear).

When the satellite signal strength is again high enough, then the receiver will resume providing desired programming services.

Install Tools and Materials

The Seaman antenna system is designed for simple installation and setup. However, the following list of equipment or items should be available during installation of the

Seaman antenna.

• Electric drill and drill bits

• Socket wrench

• Silicon sealant

• Fastener suitable for specific application

1. Verification of the Vessel’s Power Supply.

• Confirm that the vessel’s power supply is 12VDC~24VDC.

2. Verification of the Satellite Receiver and IDU’s attachment and the electricity supply

• Attach Satellite Receiver and IDU in the interior of the vessel or the trunk.

• Connect the power of Satellite Receiver and IDU.

• Once the power of Satellite Receiver and IDU is verified, it confirms that both Satellite Receiver and IDU are working normally.

3. Procedure of the satellite’s attachment and installation.

• Attach the satellite on the flat surface area of the vessel’s roof.

• Connect each end of the Coaxial antenna cable to the satellite’s terminal and the IDU.

• Connect the IDU and the Satellite Receiver box together through the coaxial cable.

• Make sure that the satellite is working normally, once the power is supplied.

12

Warnig!

• Turn off the power when attaching or detaching the antenna.

• Make sure that the attached satellite is fixed on the flat surface.

• When attaching, ensure that all the products are adhered properly.

• Ensure that all the cables are connected properly.

ENGLISH

Selecting the location

Determine the optimum mounting location for the antenna radome assembly. It should be installed where:

1. The antenna has a clear line-of-sight view to as much of the sky as is practical.

Choose a location where masts or other structures do not block the satellite signal from the dish as the vessel turns.

2. The antenna is at least 5 feet away from other transmitting antennas (HF, VHF and radar) that may generate signals that may interfere with the Seaman antenna. The further away the Seaman antenna is from these other antennas, the less impact their operation will have on it.

3. Direct radiation into the antenna from vessels radar, especially high power surveillance radar arrays, is minimized. The radome should be as far away from the vessels Radar as possible and should NOT be mounted on the same plane as the vessels Radar.

4. The antenna radome assembly should be rigidly mounted to the vessel. If necessary, reinforce the mounting area to assure that it does not flex due to the vessel motion or vibration.

If these conditions cannot be entirely satisfied, the site selection will inevitably be a

“best” compromise between the various considerations.

Perform a through site inspection on the roof for the antenna to be mounted.

1. The antenna must have a clear view of the sky and the horizon at all the directions to avoid blockage of the satellite signal.

2. The antenna should be on the top of the vessel.

Equipment and cable installation

This offers a general explanation of how to install the IDU and satellite receiver properly to the inside of vessel connecting with coaxial cable.

1. The Coaxial cable is routed from the antenna to the IDU inside the vessel.

2. After Once deciding where to place the IDU and satellite receiver, make sure that both units are placed in a dry and protected area.

3. The IDU and satellite receiver should be placed away from any heat source and in an area with proper ventilation.

4. Ensure that there are at least 3cm of space around both units for ventilation and connection of cables. Do not stack the units on top of each other.

5. The following describes the basic wiring configurations for the Seaman antenna system.

• Connect the Coaxial cable to the Seaman antenna port on the back of the

IDU

• Connect one end of the supplied coaxial cable to the receiver port on the back of the IDU

• Connect the other end of the coaxial cable to the satellite receiver

Setting the LNB skew angle

Figure 2-3 Satellite signals

Signals transmitted in vertical(red) and horizontal(blue) wave offset exactly 90º from each other. Since linear satellite signals are oriented in a precise cross pattern, the

Seaman antenna’s receiving element, called an LNB (low-noise block) must be oriented in the same way to optimize reception. This orientation adjustment is referred to as the LNB’s “skew angle.” Figure 1-4 illustrates how skew determines the amount of signal the LNB collects. The more signal, the better the reception.

ENGLISH bad skew Good skew

The correct skew setting varies depending on your geographic location, since the orientation of your antenna to the satellite changes as you move. For complete details about adjusting the LNB’s skew angle, see “Appendix A –

How to Set the Skew Angle”

Receiving Satellite TV Signals

Television satellites are located in fixed positions above the Earth’s equator and beam

TV signals down to certain regions of the planet. To receive TV signals from a satellite, you must be located within that satellite’s unique coverage area. To check it, see “Appendix B – Satellite Coverage Map” In addition, since TV satellites are located above the equator, the Seaman antenna must have a clear view of the sky to receive satellite

TV signals. Anything that stands between the antenna and the satellite can block the signal, resulting in lost reception. Common causes of blockage include lighthouses, boat masts, trees, buildings, and bridges. Heavy rain, ice, or snow might also temporarily interrupt satellite signals.

Turning the System On/Off

Since power to the Seaman system is controlled by the IDU, you can turn the antenna on or off by applying/removing operating power to the IDU.

Turning on the System

Follow the steps below to turn on your Seaman System.

1. Make sure the antenna has a clear view of the sky.

2. Turn on your satellite TV receiver and TV.

3. Apply operating power to the IDU.

4. Wait one minute for system startup. The IDU will display the Tracking Satellite screen after system testing is complete.

Turning off the System

Follow the steps below to turn off your Seaman System.

1. Remove operating power from the IDU.

2. Turn off your satellite TV receiver and TV.

ENGLISH ENGLISH 17

Changing Channels

If you have followed the installation instructions, your system should be set to the satellite of your choice and the system should have downloaded the appropriate channel guides. When the Seaman antenna system and satellite receiver is properly configured, it is easy to change the channel using the remote control that normally comes with the receiver unit.

Watching TV

The Seaman antenna is designed to operate as efficiently and as reliably as possible when the vessel is moved and anchored. It is also the quickest satellite acquisition system available among the Seaman antennas. If you have anchored the vessel and the antenna has completed to searching selected satellite, turn off IDU Power to avoid unnecessary use of power. Because the LNB receives its power from the Satellite

Receiver through the IDU, the antenna will continue to receive the satellite TV signals.

Switching between Satellites

You can switch between satellites using the IDU by pressing Satellite select buttons.

Follow the steps below to switch to another satellite.

1. Ensure that the LCD screen of the IDU is displayed

Troubleshooting

There are a number of common issues that can affect the signal quality or the operation of the Seaman antenna system. The following sections address these issues and potential solutions.

Simple Check

Causes and Remedies

27

28

Improper Wiring

If the system has been improperly wired, the antenna will not operate correctly.

Refer to the User Manual for complete system wiring information or visit website www.megasat.tv

Loose Cable Connectors

We recommends periodically checking the antenna unit’s cable connections. A loose cable connector can reduce signal quality or prevent automatic satellite switching using the receiver’s remote control. Fasten the cable connector.

22

ENGLISH ENGLISH 23

24

Simple check

Can the antenna see the satellite?

The antenna requires an unobstructed view of the sky to receive satellite TV signals.

Common causes of blockage include trees, buildings, bridges, and mountains.

Is there excessive dirt or moisture on the antenna dome?

Dirt buildup or moisture on the dome can reduce satellite reception. Clean the exterior of the dome periodically.

Is it raining heavily?

Heavy rain or snow can weaken satellite TV signals. Reception should improve once the inclement weather subsides.

Is everything turned on and connected properly?

Make sure your TV and receiver are both turned on and set up for the satellite input.

Finally, check any connecting cables to ensure none have come loose.

Is the antenna’s LNB set to the correct skew angle?

(Manual Skew Ver. Only)

To optimize reception, the antenna’s LNB needs to be set to the correct skew angle for the satellite you want to track. See “Appendix A – How to set the skew angle” for details

Causes and Remedies

Receiver Fault

Your satellite TV receiver might be set up incorrectly or defective. First check the receiver’s configuration to ensure it is set up for the desired programming. In the case of a faulty receiver, refer to your selected receiver’s user manual for service and warranty information.

Satellite Coverage Issue

Television satellites are located in fixed positions above the Earth’s equator and beam

TV signals down to certain regions of the planet (not worldwide). To receive TV signals from a satellite, you must be located within that satellite’s unique coverage area.

See “Appendix-B Satellite Coverage Map”

Satellite Signal Blocked

The Seaman Antenna needs a clear line of sight (LOS), view to the satellite for uninterrupted reception. Objects such as tall lighthouse, bridges and big ship that block this view will cause a loss of signal. The signal will be quickly restored once the antenna has a clear line of sight again. Heavy rain, cloud, snow or ice may also interfere with the signal reception quality. If the satellite signal is lost due to blockage or severe weather condition, services from the receiver will be lost (picture will freeze frame and may disappear). When the satellite signal strength is again high enough, then the receiver will resume providing desired programming services.

Satellite Frequency Data Changed

If some channels work, while one or more other channels do not, or if the antenna cannot find the selected satellite, the satellite’s frequency data might have changed.

Appendix A

How to Set up the Skew

Signals transmitted in vertical and horizontal wave offset exactly 90º from each other. Since linear satellite signals are oriented in a precise cross pattern, the Seaman antenna’s receiving element, called an LNB (low-noise block) must be oriented in the same way to optimize reception. This orientation adjustment is referred to as the

LNB’s “skew angle.” The correct skew setting varies depending on your geographic location, since the orientation of your antenna to the satellite changes as you move.

This appendix provides how to set up the skew angle.

European Position Grid

If you wish to determine the Skew Angle(LNB), use the position grid(Figure A-1 European Positon Grid) and table(TableA-1 Regional Skew angle) on page 32.

If you wish to set the correct skew, see “TableA-1 Regional Skew angle”. The correct skew setting varies depending on your geographic location, since the orientation of your antenna to the satellite changes as you move.

Setting the Skew Angle

If you have determine the correct skew angle, follow the steps below to adjust the antenna’s LNB skew angle.

Caution – To avoid bodily injury, be sure to turn off the antenna and disconnect power to all wored components.

1. Turn off the antenna and disconnect power to all wired components.

2. Using the screwdriver, remove the screws securing the radome. Then remove and set it aside in a safe place.

3. Locate the LNB assembly on the back of the antenna reflector.

Satellite Coverage Map

Satellite TV broadcast spot beams are aimed at land masses where the bulk of subscribers can be found. Thus, the signal strength decreases as you travel away from the land masses. The further you travel offshore you will require a larger size antenna.

Although this information is believed to be correct, MEGASAT Technologies has no control over the variations on the actual satellite footprint coverage. Signal strength and reception can be affected by the weather conditions.
