Difference between Linear & Circular LNB and LNBF & Satellite Signals
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.
