MacMININEC is an antenna analysis program for the Mac. Any type of antenna may be studied. The physical design of the antenna is entered (such as the lengths of wires and elements). For a given frequency, the feedpoint impedance is calculated, along with theoretical efficiency. Plots of the radiation patterns may also be displayed and printed.
MacMININEC is freeware.
MacMININEC does not run on newer Macintosh models. It will not work on PPC systems, and probably will not work on versions of System past 7.1. But if you've got an older Mac laying around, give it a try!
MacMININEC is only available for Macintosh systems. No Windows version is available.
