It is shown that the equivalent edge currents (EEC) obtained in terms of the uniform geometrical theory of diffraction coefficients (EEC‐UTD) yield accurate values of the radiated far field in the boresight caustic region of a paraboloid. Failure of the equivalent edge current technique to provide the correct values for boresight region fields in a previous article is attributed to the reflector edge representation in that article. Radiation patterns computed by the EEC‐UTD method are found to blend well with the pattern obtained by the UTD technique. © 1995 John Wiley & Sons. Inc.
