"satellite dish"的定义和意义

What is a "satellite dish"?

A satellite dish is a large, curved antenna used to receive signals from satellites in space. It is typically made of metal or plastic and is mounted on a stand or on a roof. The dish collects signals from communication satellites, which are then sent to a receiver in a home or building. Satellite dishes are commonly used for television reception, internet services, or radio signals, especially in areas where cable or traditional broadcasting is unavailable. They are designed to capture signals from a specific satellite by pointing in its direction.
