xnec2c - 1:4.1.1-1 main

The original nec2c is a non-interactive command-line application that reads
standard NEC2 input files and produces an output file with data requested
by "commands" in the input file.
.
In contrast xnec2c is a GUI interactive application that (in its current form)
reads NEC2 input files but presents output data in graphical form, e.g. as
wire frame drawings of the radiation pattern or near E/H field, graphs of
maximum gain, input impedance, vswr etc against frequency and simple rendering
of the antenna structure, including color code representation of currents or
charge densities. These results are only calculated and drawn on user demand
via menu items or buttons, e.g. xnec2c is interactive and does not execute
NEC2 "commands" in batch style as the original does.
