HAAT

Calculation of height above average terrain (HAAT) requires input of the coordinates of a specific location, the height of the antenna, and the ground elevation. EWA can automatically calculate the elevation based on geophysical data from industry sources, but you are welcome to provide specific input if you have it. You may further specify the number of radials upon which HAAT is calculated (use 8 unless you have other specific requirements).

An accurate location can only be determined if you are using a wireless network.
