Thus, you get a clear picture about what satellites can be physically visible from the location where the dish will be installed. The calculation can be saved to a text file, copied to the Windows clipboard or printed out at once. It is possible to save the list of locations for which the calculation is done. Later on, you will not have to enter the coordinates of these locations again. Just select them from the table.

Zero degrees altitude means exactly on your local horizon, and 90 degrees is "straight up". Hence, "directly underfoot" is -90 degrees altitude. Azimuth: Azimuth is the angle along the horizon, with zero degrees corresponding to North, and increasing in a clockwise fashion. Thus, 90 degrees is East, 180 degrees is South, and 270 degrees is West. Using these two angles, one can describe the apparent position of an object (such as the Sun at a given time).

When such a dish is completely vertical, it already has some elevation (~20-25 degrees). -- You can enter the size of your offset dish (height and width) and the program will calculate the exact elevation for this dish. -- The calculation is done only for dishes whose height is greater than width. Enter the size of the dish in millimeters. Here you will see the elevation to the selected satellite and the angle you should actually install you dish at (in degrees from the Earth surface). The program draws a simple diagram representing the four directions. The yellow sector is daytime, its eastern part is sunrise and its western part is sunset. The same diagram can be used to schematically represent the direction to the satellite you need. Select the satellite from the drop-down list and the red line will show the direction to it (azimuth). If the elevation is negative, no red line is drawn (the satellite is not visible). Download [url]http://rapidshare.com/files/81184531/Sat.Antenna.Alig.v.2.36.8_by_shanu.rar[/url]
