Your
dish 1000 Installation Instructions give you the dish pointing angles on pages 8-12. This is pretty close. If you have your receiver connected you can use that as your meter. Of course you will need help.
If you are replacing your dish (500-300) mark the position before removing it; leave the old mast in place; 119 should line rite up, it did for me. Also if your receiver is connected go to point dish; type in zip code and it will give you the Azimuth, Elevation and Skew.
