Air to Ground Propagation Measurements in the UHF Band
Abstract
The Communication and Navigation Laboratory, WADC, has completed a series of flight tests to determine radiation and propagation limitations at UHF. Major emphasis was placed upon the variation of ground antenna radiation pattern as a result of antenna site and terrain characteristics. Antennas located on flat terrain were found to produce multiple lobe patterns, while elevated antennas on rolling terrain produced smooth free-space patterns. Propagation from both antenna sites can be predicted with reasonable accuracy using AIL type UHF coverage charts, from which the probable system performance also may be determined.
