Combine & Split or Seperate Satellite and OTA & Cable Signal Combine & Split or Seperate Satellite and OTA & Cable Signal

Note, that all the diagrams above that show the use of a multi-way switch uses a dual LNBF.  In order to understand the need to use a dual LNB with a multi switch, you must know that the satellite signal broadcasting from the satellite broadcasts in two different ways.  Either Horizontal & Vertical for FSS FTA or Right Circular & Left Circular for DSS.  Horizontal and Left Circular operate on 18V DC and Vertical & Right Circular operate on 13V DC.  When you use a multi-switch, the input ports for the LNB is marked as 13V or 18V.  If  you only use a single LNB and run your one cable to the 13V port, you can only get channels that are broadcasting on Vertical or Right Circular.  If you install it on the 18V port, you can only get signal from Horizontal or Left Circular transponders.  When you use a dual LNB, one port will provide Horizontal or Left Circular, the other provides Vertical or Right Circular.

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.


Understanding Circular & Linear Polarizations

Vertical Horizontal Left Circular Right Circular


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.
