Comment on "Incompleteness of the periodic moment method": correction

It was previously shown by the author (see ibid., vol. 29, no. 14, p.1245-6, 1993) that the periodic moment method (PMM) predicts the correct impedance between a dipole in a planar array of dipoles with rectangular lattice, and a single dipole in a parallel plane, when the single dipole is also parallel to the array dipoles. Also it was asserted that when the single dipole was inclined the PMM results were incorrect; a correct formula for perpendicular dipoles was presented. S. Schneider of the USAF Wright Laboratories has shown how a correct formulation for the parallel plane PMM case can be obtained, and that a coding error of a missing factor of 2 was made by the author for the limiting case of |α|=1. Now the calculated results agree with those the author calculated using the Richmond piecewise sinusoidal code
