Here is our setup for DirecTV. Setup and alignment is pretty simple. I use the signal strength meter in the HR44 receiver. I can glance in the side window of the trailer and also listen to the beep.
Here is the app I use for setting the Tilt(LNB skew), Elevation, and Azimuth. It uses the GPS on the phone.
Here is a composite of the signal strengths that I receive.
There is also another very good app called Satellite AR which lets you visualize where the DirecTV satellites are for your location.
Tip: You set the Tilt and Elevation after you have leveled the mast. Before you bolt the reflector on use a compass or the compass on the SatFinder app to approximate the correct azimuth by visually aligning the LNB with the mast assembly. It will save you time.
