I want to take a small dish that was used by someone else for “bad things” and remove the circular lnbf’s and stick on a linear one and “play” with it to see what FTA I can receive. But I am confused about something. My big dish has “parts” in it that change the polarity. How is this taken care of with just the lnbf sitting on the end of the arm? Is there something inside it that does the job?:confused:

the polarity is switched by the receiver....it sends different voltage to the lnb to switch between horizontal and vertical tps....
