MININEC Pro has been updated to version 1.4.0. This update fixes several bugs, and adds a few sample antenna files directly into the app, as examples to assist with learning how to use it.
Enter in the physical design of the antenna (lengths and locations of wires / 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. The impedance over a frequency range may also be plotted
MNINEC Pro is available for Windows (XP through Windows 10) as well as Mac OS X (10.6 though 10.10) and can be downloaded here:
