With regard to zoning restrictions, you should be aware that the FCC has taken actions to discourage local jurisdictions from placing restrictions on certain satellite-based communications equipment. Satellite transmissions require a direct and unobstructed path between the satellite and the antenna. As you read the rest of this section, you need to have a basic understand of two words as they relate to locating the position of the satellite. Azimuth is the reference point on the horizon, based on a 360 circle where 0 is North and as you turn in a clockwise direction, the number increases. If you are using a compass, you should use the Magnetic North azimuth reading.
Elevation means the angle, in degrees, above the horizon.
If you are pointing straight up, the angle is 90. So a 45 elevation angle would be halfway between 0 and 90, a 30 elevation angle would be one-third of the distance above the horizon, and so forth. Table 1 gives some reference points from a geographic sampling of cities in the lower 48 United States. Find the Zip Code and city nearest where you live and look up the elevation and azimuth coordinates for that location. The use of approximations for degrees of angles in determining azimuth and elevation is appropriate.
