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 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 DSS.
DSS 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 BSC421,
BSC621, and
BSC621-2
(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.
