FAQ for LNB
LNB and LNBF stand for?
LNB stands for
Low Noise Block. LNBF stands for Low Noise Block Feed.
What is the
difference between LNB and LNBF?
only receives signal from 1 polarity (Vertical or Horizontal for Linear
FSS and Right or Left for Circular DSS) A good example of of a LNB
ASC511 Ku LNB. Another good example is our C band LNB the
BSC211. The rest are mostly LNBF's. Usually Vertical and
Right polarities operate on 13V DC and Horizontal and Left polarities
operate on 18V DC.
What is the
difference between a Standard Ku band LNBF, Normal Ku band LNBF, and
Universal Ku band LNBF?
There are 3
main types of LNBF's. The first is Standard. Standard &
Normal LNB and LNBF's are the same. They are FSS linear and the
frequency range is from 11.7GHz to 12.2GHz. The second type of
LNB/F is Universal. The frequency range for a universal LNBF is
10.7GHz to 12.75GHz. This is more popular in Europe and the Middle
East because their satellite broadcast within the 10.70GHz to 12.75GHz.
The third and the most popular in the United States for DISH Network &
DirecTV is DSS. DSS LNBF's are always circular. The
frequency range is 12.2GHz to 12.7GHz.
What is the difference between a
Linear and Circular LNB?
This has to do with the way the
signal is transmitted from the satellite in the sky.
There are two different ways that a satellite can
broadcast its signal. If linear, it broadcasts
Horizontal and Vertical. If circular, it
broadcasts Right Circular and Left Circular.
To understand this better, imagine the signal coming
in like a screw that's turning left or right.
Understanding Circular & Linear
How do I know if I need a linear or circular LNBF?
Click Here or go to lyngsat.com and choose the satellite you are
trying to pick up. Under the transponder frequency column (Freq.
Tp) you will see a letter next to the frequency. If the letters
used are R or L (Right or Left), then it's a circular broadcasting
transponder. If you see the letters H or V (Horizontal or
Vertical), then it's a linear broadcasting transponder.
