A parabolic antenna is a type of satellite dish that uses a curved, reflective surface to focus signals onto a receiver. The shape of the antenna resembles a parabola, which allows it to collect and direct radio waves efficiently. This design is commonly used for communication, broadcasting, and satellite transmissions. These antennas can be found in various sizes, from small dishes for home use to large installations for commercial purposes. They are often used in conjunction with devices like satellite receivers and transmitters to facilitate clear and reliable communication over long distances.
