The world of television entertainment has changed after the advent of the satellite television system. There is no equipment to buy and all the features required are available. Installation is done free of cost and even the dish system is free. There may be a small cost for the programmes. It is necessary to have knowledge of how this system works.
Satellite television is a wireless system. Television programmes are delivered directly to a viewer’s home through this system. The broadcasts are transmitted through radio waves.
Unlike premium satellite services, free to air satellite services need no subscription. The satellites orbit the earth at the same speed as the earth’s rotation and that is why they seem stationary from earth. The satellites orbiting the earth that are used for television are all located in the “Clark Belt”, named after the famous science fiction author.
The satellites basically work like a mirror. The signals sent from a station on earth to the satellite, bounce off its surface to another dish on earth. The programmes are beamed from the television stations to the satellites orbiting the earth, via radio waves. These signals travel 20,000 miles from the broadcast station to the satellite in the sky, from where they are bounced back to earth. These signals travel another 20,000 miles where they are received by a small satellite dish on the roof of a building or some other location. The dish transfers the signals into the television receiver. They are then processed and made into pictures that can be viewed on a television screen. The audio and video data which is sent from the television station is contained in the radio waves or signals.
The receiving dish antenna is curved and it has a LNB receptor at its center. The signals received by the curved dish are directed to the LNB receptor where they are strengthened and passed along to the receiver. It is important that there should be no obstructions like trees or buildings in the path between the dish and the satellite.
Satellite television is becoming popular with more and more viewers opting for it over cable television. This is because of its quality programming and reliable service. Satellite television delivers 100 % digital programming with a high quality of picture and sound.
When opting for a satellite television service the viewer will receive brand new equipment which is installed free of charge. This includes a satellite television dish antenna, a digital receiver for processing the radio waves into pictures, access cards, a remote control and required cabling. This is all professionally installed for free and normally within a day or two.
