Several people have asked for the elevation and tilt to install their AT9 dishes before they have their H20 receiver. Rather than keep posting the same info, I thought I'd just post it here in it's own little thread. :)

Go to

Select DirecTV 1R/2/3 @ 101 and enter your zip code.
The correct elevation and azimuth will be displayed.
To determine the correct tick mark for the tilt, subtract the result from 90.
For example, if the tilt shows 26.3, it would be 90 - 26.3 = 63.7
If the tilt is negative, for example, -23.5, it would be 90 - (-23.5) = 113.5.

The results should line up with the output from an H20. (Except the H20 will round the numbers)

You can also use the azimuth and elevation settings in the receiver for the single LNB 18" dish. You have to rotate the tilt anyway, so starting with the tilt at 90 degrees shouldn't matter for someone basic dish pointing experience. Peak 101, switch to 119 and peak tilt, then follow the rest of the instructions.
