UHF Radio Propagation Data for Low Antenna Heights Volume I

Laurance G. Hause; F. George Kimmett; John M. Harman

Abstract: This report is a presentation in two volumes of measurement techniques, data, comparisons, and conclusions obtained from a UHF propagation measurement program at 230 and 415.9 MHz. Antenna heights were 3 m or less above ground. Vertical polarization was used, and the antennas were omnidirectional in the horizontal plane. The terrain was generally rocky, hilly, and relatively free of trees. Path lengths varied from 2 to 45 km. Volume 1 describes the equipment, techniques, and results and presents data from the Wyoming area, including some buried antenna tests. Volume II presents data obtained in Idaho and Washington.

Keywords: buried antennas; low antennas; path loss measurements; UHF propagation; vertical polarization
