A satellite dish is a telecommunications device used to send and receive microwave signals. It is a parabolic shaped antenna used for data transmission and broadcasting.
The primary function of a satellite dish is to convert microwave signals into electric signals that can be used by a computer, television and other devices. The low-frequency signals can be received by the larger dishes, whereas small dishes are used for higher frequency signals.
Satellite dishes are used for all kinds of data communication. The signals can be sent anywhere without having miles of cables.
