Book Description

Information contained in this publication may be used to estimate gross transmission characteristics at frequencies of 125, 300, 1600, 5100, and 15,000 MHz. Curves of long-term median basic transmission loss are given as a function of long-term median basic transmission loss are given as a function of (1) path distance for antenna elevations of 0.025, 0.050, 0.1, 0.5, 1, 2, 5, 10, 15, 25, 30, 40, 60, 80, 100, and 150 thousand feet off the ground, and (2) actual direct ray takeoff angle for the same values of antenna elevation, but with one terminal fixed at synchronous satellite altitude. The methods used to develop these curves and propagation considerations that may be important when applying the curves to specific problems are discussed.
