What is an LNB?
Low Noise Block-down converter (so called because it converts a whole band or "block" of frequencies to a lower band).
Also incorrectly known as a "Low Noise Block" or a "Low Noise Blocker"!
An LNB sits on the end of an arm and faces the parabolic reflector ("dish") which focusses the signals from a satellite 24,000 miles away into the "feed horn" of the LNB (see pictures below).
The LNB converts the signals to a lower frequency and sends them out to the cable connector, which you connect to your satellite receiver via coaxial cable.
What is an LNBF?
This is the term for an LNB with an integral feed horn. Nowadays the "F" tends to be omitted.
What is an LNC?
Low Noise Converter. Basically the same thing
