EFFECTS OF LOCAL TERRAIN AND OBSTACLES UPON NEAR HORIZON GAIN OF L-BAND BEACON ANTENNAS

Models are given of the mechanisms that determine the effective gain of an L-band ground based antenna at near horizon elevation angles. Primary emphasis is given to the environment of typical Air Traffic Control Radar Beacon System (ATCRBS) sites.
