The Yagi Designer program was first developed in 1992 on a DEC-Vax 3100 and written in Fortran, and the output was graphed in Mathematica 2.0. It has since been converted into a DLL with lightning fast speed compiled in the C language. It was written by a physicist that has always enjoyed dabbling in radio.
