Satellite television
Satellite television is a way of sending television signals. Television channels go to a ground station, which sends them by radio waves to a communications satellite in space. The satellite then transmits that signal back to earth. People with a satellite dish can receive the signals. Very often, satellite television is provided as a pay television service (especially to places where cable TV is not available). Here are some examples:
- Sky (UK)
- Freesat (UK)
- Dish Network (US)
- Astro (Satellite TV)
