Question 2
To transmit a signal, a controller sends it through the horn, and the dish focuses the signal into a relatively narrow beam. When the signal reaches the viewer's house, it is captured by the satellite dish. A satellite dish is just a special kind of antenna designed to focus on a specific broadcast source. The standard dish consists of a parabolic (bowl-shaped) surface and a central feed horn. To transmit a signal, a controller sends it through the horn, and the dish focuses the signal into a relatively narrow beam.
Based on the above figure, answer the following questions:
