What this is: When you need to figure out how far away from an object/obstacle (like a building or large tree) you need to park your satellite truck or place a flyaway dish in order to see over it for a clear line of sight, use our Line of Sight calculator tool along with the CMG Look Angle Calculator to figure it out. Instructions:
    Go to the CMG Look Angle Calculator; select the satellite and city and calculate the look angle for the Elevation.
  1. Enter the Elevation from the CMG Look Angles Calculator in the "
  2. Click the "Compute" button
  3. The answer computed is the minimum distance, in feet, that you need to be from the object/obstacle in order to see over it for a clear line of sight.

the minimum distance from the obstacle:
