FAQ for LNB / LNBF:

 

What does 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?

LNB usually 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 is our 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.

 

 

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.
