The LNB is the component located at the end of the arm projecting from the
satellite dish. It converts the Ku-band signal beamed from the satellite to a
3.7 - 4.2GHz signal, then filters out low-end frequencies and amplifies the
high-frequency signal before sending it to the LNB's coaxial output(s).
Satellite service providers (such as DIRECTV) have satellites in multiple
orbital positions, and a separate LNB is needed to access each satellite
position. Essentially it just 'tunes' the feed from the satellite. |
