In addition to what the others have said...
If you can stand at the dish and see the TV displaying the Point Dish Screen, then do this.
- Slightly push the end of the LNBF arm, or the LNBF, upward and then downward. I'm talking about a hair or two, and not enough to push it over.
- Then slightly push it to the east, and then slightly to the west, just a hair as above.
If you were to do the above on a perfectly aligned dish, your signal would either get weeker or disappear, since this very minor movement would be quite a bit 22,300 miles out in space.
But if you are slightly out of adjustment, you may actually see an increase in the signal when attempting the above 2 sets of movements; leaving no doubt the dish needs to be re-peaked.
As said, it is easy to do, but you must go very slow, and by doing the above test, you learned that you can only move it a very very little bit at a time to peak it. If east and west gave you the better reading, then loosen the bolts so that you can twist the dish, but wait about 8-10 seconds in between each reading for the receiver to respond. You may also want to peak the elevation. However, I would not touch the Skew which is rotatiing the dish either clockwise or counter clockwise.
If your pier has settled, then you may want to go a little further.
- Check and make sure the top of the mast where the dish mounts at, is plumb in all directions.
- The skew (tilt or rotation of the dish pan) should already be set, don't touch it.
- Then peak the elevation (up/down).
- Then peak the azimuth (east/west).
And remember to make slow hair size movements to adjust.
At least try it before you leave.
