Mass Media Calculated Contours
FM Example TV Example

These contours were generated from the FM and TV engineering databases. The contours were created by calculating the Antenna Height Above Average Terrain (HAAT) and Effective Radiated Power (ERP) for each of the 120 radials at 3 degree intervals. Both HAAT and ERP were calculated for each radial using a three arc second terrain database and the linearly interpolated antenna gain.
