Lemme guess, measures 18" H x 22" W
You got ripped off at $23
I circled the one that You'd be aiming with for whatever E* bird.
The other two only pick up higher frequency transponders.
Going by the DirecTV multiswitch,
leaving 22kHz tone OFF, either 13V or 18V chooses the Left one going by the picture, LNBF between you and the Dish.
turning 22kHz tone ON, 18V chooses the Middle one
turning 22kHz tone ON, 13V chooses the Right one
I pulled off the LNB assembly, and mounted a regular LNB to get Whitesprings.There are some threads where folks ghetto rigged a KU LNB on it for some of the higher powered signals
