Dish offset and trees ?

[sat_action]

Hi, I recently purchased a Fortec 90cm dish from Sadoun, and have been looking at possible installation sites. While trying to figure out if I can "see" over a tree in my front yard - a search brought up this post, excerpt:

If you have a Fortec 90cm, the offset is 24.62 degrees. So calculate the elevation for G10R ; lets say for example it turns out to be 30 , then find the offset, and add both. So 30+24 = 54. Or 55 we can say.
So point your dish to G10R's azimuth and lift your dish on it's scale to 55 and the dish will exactly be pointing to where the signal is coming from. Like this you can determine if you will catch signal.
Of course, you will get no signal and quality like this, because offset dishes work when they are offset. You would have to subtract 55-24 again to get 30 and thats where you should leave the dish for signal.

Being somewhat confused (like Jerry), I drew this:

Is this correct...the black line would represent the true angle to the satellite?

And calculate the elevation means? (i.e. SatMex 5 at 116.8° W, elevation = 51.8°?)

the easiest way that i have found without installing dish is to use a compass and a inclinometer. for your longitude set compass to point to164.6 degrees. use a 2 by 4 with inclinometer set to 52 degrees and point at compass setting to see if trees or other obsticals will interfere with your line of site. check this sitehttp://www.sadoun.com/Sat/Installati...Calculator.htm :mozilla_smile:

Thanks rainman, you're the wiz! =D>
