An Atlas of Basic Transmission Loss for 0.125 to 15.5 GHz

Abstract

This report provides an atlas of air/ground and air/air basic transmission loss predictions made with the IF-77 (ITS-FAA-1977) propagation model. Sets of predictions are provided for each of six frequencies; i.e., 0. 125, 0.3, 1.2, 5.1, 9.4, and 15.5 GHz. Each set contains curves for 90 antenna height combinations where one antenna height varies from 3 to 30,000 m, and the other varies from 300 to 30,000 m. Each height combination is repeated for three time availabilities: 0.05, 0.5, and 0.95. Hence, 1620 transmission loss versus distance curves are provided. The maximum distance used in 1800 km. Propagation factors and application considerations are discussed. Example problems are used to illustrate the various application methods provided. (Author)
