What does LNB stand for on a satellite system?

LNB stands for Low Noise Block downconverter. It is a device used in satellite television systems to receive and amplify the weak signals transmitted from a satellite. The LNB is typically mounted on the dish and points towards the satellite. It converts the high-frequency signals from the satellite into a lower-frequency signal that can be processed by the satellite receiver. The LNB also amplifies the signal to improve the signal-to-noise ratio, making it easier for the receiver to decode the signal.
