What are the parts of a satellite dish?

A satellite dish is just a special kind of antenna designed to focus on a specific broadcast source. The standard dish consists of a parabolic (bowl-shaped) surface and a central feed horn. To transmit a signal, a controller sends it through the horn, and the dish focuses the signal into a relatively narrow beam.

Is LNB skew important?

When you are getting a good strong signal, the skew setting is not mega important.
