The following are included for calculating the efficiencies of parabolic
dish feeds:
DISHFD1.BAS Calculates aperture efficiency based on full axial symmetry.
Instructions for input file are in the BASIC listing.
DISHFEED.BAS An embellished version of DISHFD1 that allows two patterns,
normally the E-plane and H-plane. Also calculates the
efficiency of (cos x)^n fed patterns for comparison with
antenna texts such as Silver.
DHB_A_E.DAT Pattern data file for E-plane of W7PUA Double Handlebar
type A feed.
DHB_A_H.DAT Same for H-plane.
DHB_B_E.DAT Same for E-plane of type B feed.
DHB_B_H.DAT Same for H-plane.
EIA_E.DAT Pattern data file for E-plane of EIA reference antenna (two
half wave dipoles space 1/2 wavelength apart and 1/4 wavelength
over 1 wavelength by 1 wavelength solid reflector.)
EIA_H.DAT Same for H-plane.
