A freeware dos program by John Agrelius released in early 90’s but still very actual. It allows to quickly calculate dimensions for Quads antennas, Yagi antenna, Inverted vees antennas as well as J-poles and Traps to extend dipoles band coverage. Just extract the antmaker.zip file and start the Menu.exe batch file.
Even if outdated, is still a good program to calculate and desing yagi antennas elements dimensions, sizing and spacing. I’ve used it to verify some antenna plans I’ve found on the net. It’s particularity is that you at first need to tell the program the size of your antenna and then, you can calculate resonating
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.
