Yes....Harshness is correct: there is a Dishpointer entry for Shaw further down in the dropdown box whose numbers are slightly different than the F2 numbers. I had forgotten that. However, either set of numbers can be used for getting started with the pointing operation.
If you use Dishpointer, enter your EXACT address, and use its photo image of your area. It is much easier to point your dish this way than it is by fiddling with a compass. Keep in mind that a compass is subject to local attraction such as metal objects, power lines, etc, and also subject to the declination (difference between magnetic & true, which changes over time). Using the Dishpointer photo makes it a very simple operation to aim to the correct azimuth. Pick out an object in the photo along the red line shown, stand behind your dish, use your eye, the center-top of the dish, and the F2 side of the LNB and aim to that object. Make sure that the skew and elevation are correct before doing the azimuth pointing. Make sure your mast is perfectly plumb in all directions, or else your settings for skew and elevation will be for naught. Use a carpenter's level.
With regard to the "numbers", if your dish was working before, and if the settings for skew and elevation weren't disturbed during the shingling operation, they should not require any adjustment now. So you only have the azimuth to worry about.
If you're getting a signal in the 40's (as you mentioned before), make VERY small adjustments for azimuth by just nudging the dish with your hand (the clamp being just loose enough for it to move left or right). After each adjustment, wait a few seconds for the signal meter to react. You should see the signal go up....or down. Continue to make adjustments, back and forth, left or right, accordingly. Once you get a maximum signal for azimuth, carefully tighten the clamp. If you're still not satisfied with the signal level, try the same nudging procedure with the elevation, up or down. You should not have to fine-tune the skew if it was set properly before you started.
If you are getting a weak signal level of, say 20, it may be a false reading resulting from background "noise". Then you need to start looking at your connections and cabling to see whether they are broken or corroded. The signal meter may show this kind of a weak signal even if the the connection between your dish and your receiver is completely broken.
With regard to the trees, it's difficult to tell from the photo you provided. Keep in mind that an elevation of 29 degrees is about one-third the way up from the horizon to the vertical. Try to estimate, by looking at the mounted dish from the side view, as to whether there could be a line-of-sight issue with the trees. Also keep in mind that the true location of the satellite is actually a little higher in the sky than you might guess by looking at a side view of your dish.
Good luck!!
