Space and Frequency diversity measurements on a line-of-sight path in Ohio
Richard E. Skerjanec; Charles A. Samson; C. F. Peterson
Abstract: Propagation measurements were made at 6. 8 GHz during August 1967 over a 65-km. line-of-sight path in Ohio. During three periods of severe fading, both space and frequency diversity provided marked improvement over nondiversity operation. Comparisons between types of diversity were inconclusive because of the small size of the data sample. A study of synoptic weather during the period indicates that severe fading on this path is most likely with a stagnant high pressure cell over Ohio and very moist air at the surface.
