The Azimuth & Elevation Calculator below will help you determine the elevation and azimuth settings for your dish to receive transmissions from AMC-18 at the longitude of 105 degrees west. Elevation is the angle above true horizontal that the antenna must be pointed to. Zero degrees elevation is pointing right at horizontal; 90 degrees elevation is pointing straight up. Azimuth is a compass direction, in degrees East of True North. True East is 90 degrees azimuth, True South is 180 degrees, and True West is 270 degrees. In most of the United States, the view of AMC-18 is between 145 and 235 degrees East of True North.
You don’t need to know the exact location of True North or the exact azimuth to point the antenna. If your antenna lets you set azimuth and elevation without one affecting the other, you should set the elevation first, then sweep the southern sky until the satellite is found. If you are east of Denver, AMC-18 will be in the southwestern sky. If you are west of Denver it will be in the southeastern sky. If you are at the same longitude as Denver, the satellite will be roughly due south of you.
