Abstract : A method is described for utilizing the circularly disposed antenna array, such as that of the University of Illinois, for determining the elevation angle of arrival of high frequency radio waves. The method described compares the amplitude of two vertically attached horizontal dipoles. Data are presented to illustrate the feasibility of identifying different modes of propagation with this method. (Author)
