UHF PROPAGATION MEASUREMENTS FROM ELEVATED TO BURIED ANTENNAS

Abstract

The report describes many of the UHF propagation characteristics between aircraft or satellites and buried antennas. A vertical monopole was used as a reference antenna, and the propagation characteristics of an annular slot and other antennas, omnidirectional in azimuth, were measured. The effects of reflecting planes used in conjunction with buried elementary antennas were measured. Site power gain patterns were measured from the buried antenna site at elevation angles up to 70 degrees. These tests were made over a reasonably smooth plane, on paths of 0.03, 0.06, and 1 km, and at various transmitting antenna heights, with a helium filled balloon. In some of the tests security fences were used.
