A satellite dish is a type of antenna designed to receive signals from satellites in space. It is typically round and made of metal or plastic, which helps to capture and focus signals onto a receiver. These dishes are commonly used for television broadcasts, internet services, and other forms of communication. The dish works by reflecting signals from a satellite, such as those in low Earth orbit, to a central point where a receiver is located. This technology allows users to access a wide range of channels and services, making it popular for both residential and commercial use.
