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.
