You need to know the off-set angle of the dish and then do the math for the reading on the protractor. If you don't know the off-set you can use the "Satellite Antenna Alignment" program. You can download it free here:OK, I am missing something. What assumption are you making and what does it tell you? Obviuosly you are reading some sort of offset.
WELL....You need to know the off-set angle of the dish and then do the math for the reading on the protractor. If you don't know the off-set you can use the "Satellite Antenna Alignment" program. You can download it free here:
SAT - Satellite Antenna Alignment (Satellite Dish Alignment)
With this program you enter in the width and height of your dish and it will calculate the off-set.
You are correct, this program only works for elliptical dishes that are taller then they are wide. When we speak of "elliptical dishes" I fear we are using the term for an egg shaped dish with out thinking about horizontal or vertical. I believe this program is using vertical - with the thinking that both the LNBF and the satellite are viewing a circle. It does the math for the amount number of degrees you would need to tilt the dish away from the LNBF so that the dish appears to be a circle. That would then be the offset degrees number.WELL....
I have Channelmaster / Primestar dishes. The width is greater than the height. I can not seem to get this program to do anything for me. I did realize the mark for the Elevation was above the bolt instead of below it , so now that seems to be working better. I had my AZ figured out almost perfectly, but could not get a signal. I went to the top of the bolt and got the signal just as soon as The mark lined up. A little lean to the east and every thing came in strong.
BUT, I need to know the offset of the dish because one install I will need to do, the pole can not be aligned plumb.
THOUGHT: Do I just put the board up, read what I see and add/subtract from what I know is the elevation, or vise versa and use that? As in the case you listed I would read 18.2 subtract that from the elevation of 42.2 to and come up with an offset of 24, Then use that offset (24) in my future calculations? If this is the case, once we found a working satellite, anyone could figure the offset that would work every time!
