Abstract : Two user-oriented computer programs are presented and described for analyzing radiation from linear arrays of vertical thin-wire antennas over the horizontal plane surface of an imperfectly conducting earth. The first program can handle arbitrary excitation of the array wire, although it is assumed they are equally spaced and all of the same length and radius. The second program is equipped to treat unequally spaced arrays of wires that can be of different lengths and radii, but it is assumed the wires are all centerfed. Both assume the wires are unloaded and that the conductivity of the earth is finite. The effects of the imperfectly conducting earth are accounted for approximately by using the method of reflection coefficients. Computed output consists of current distributions, input impedances, and far-field patterns specified by the user. (Author)
