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 DMX211 C band LNB. The rest are mostly LNBF's. Usually Vertical and Right polarities operate on 13V DC and Horizontal and Left polarities operate on 18V DC.

Yes
LNB has one poliarity
LNBF has two poliarity

lnb's have to have a separate feedhorn to work where as a LNBF has the feedhorn built in.

I posted a review comparing the bullet vs the standard LNBF in the General Ku Band Discussion forum. Titled: Conventional linear LNBF verses bullet LNBF
I would encourage installers to read it.
