My dish was installed by a DirecTv installer on a pole mount. The pole was not set plumb. I do not want to call them back to correct their error. I would rather not re-set the pole.
My signal readings seemed slightly low to me. I bought an Acutrac 22 Pro and re-aligned the dish. Since the pole is not plumb, the approach I used was several sequential adjustment and dithering cycles. That is, I would adjust the tilt for maximum signal, dither the elevation and then the azimuth. Repeat several times. Now, when dithering there is no change made - dithering results in the dish elevation and azimuth staying exactly the same. After this procedure, all of my readings are generally 2 to 4 points higher than they were.
1) Is this the proper way (several cycles of tilt adjustment and then dithering) to align a dish on a mount that is not plumb?
2) Is there a better way?
These are my readings (after my alignment) on a clear day:
