Abstract :
Finite-range effects are incorporated into Schelkunoff´s pyramidal-horn gain formula, which is arranged as the product of in-phase aperture gain and E and H plane range and slant-length gain-reduction factors. These factors, readily computed, permit the on-axis gain of a horn to be obtained from two single-line curves.
