How does the LNB know which side (even or odd transponders) to look at?
This is done by voltage changes that your DirectTV receiver sends. What is a Dual LNB? A Dual LNB is just two LNB’s…each connection can operate independently of each other so you can have two receivers each looking at different stations on different transponders. They both look at the same satellite (101 Degree satellite). A single LNB only has one coax connection and cannot be used with more than 1 DirectTV receiver.
