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 ESX211.  The rest are mostly LNBF's.  Usually Vertical and Right polarities operate on 13V DC and Horizontal and Left polarities operate on 18V DS.


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 DSSDSS LNBF's are always circular.  The frequency range is 12.2GHz to 12.7GHz.


What is the difference between linear and circular LNBF's?

Linear covers Horizontal and Vertical.  Circular covers Left and Right.  Circular hits your dish more like a screw that is turning as its coming down. 


Is C band Linear or Circular?

C band, just like Ku band can be either linear or circular.  Most C band satellites are linear rather than circular. 


Are your C band LNB or LNBF's Linear or Circular? 

Our ESX241, ESX242, and ESX244 (C-band LNBF) models come with a di-electric plate which allows the reception of circular signals as well.  Without inserting the di-electric plate, the LNBF only receives linear signal.


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.
