Satellite TV works by transmitting television signals from a satellite in space to a satellite dish installed on the viewer's property. The key components of a satellite TV system include: 1. Satellite: A geostationary satellite is positioned in space to receive, amplify, and transmit TV signals. 2. Broadcast Center: TV channels and programs are transmitted from the broadcast center to the satellite, where they are uplinked for transmission. 3. Satellite Dish: The viewer's satellite dish receives the signals from the satellite. It consists of a parabolic reflector that focuses the signals onto a feedhorn. 4. Feedhorn: The feedhorn is located at the focal point of the satellite dish and collects the signals, converting them into a lower frequency for transmission. 5. Low Noise Block (LNB): The LNB amplifies the received signals and filters out any noise or interference. 6. Coaxial Cable: The LNB is connected to the viewer's satellite receiver through a coaxial cable to transmit the signals. 7. Satellite Receiver: The satellite receiver decodes the signals received from the satellite into audio and video signals that can be displayed on the viewer's TV. 8. Television: The TV set receives the audio and video signals from the satellite receiver and displays them for the viewer to watch. By receiving signals from the satellite and processing them through the components of the satellite TV system, viewers can access a wide range of TV channels and programs.
