cocoaNEC is a Mac OS X application intended primarily for the design and modeling of antennas.

The application is free and it can be downloaded from the Download Now link.

What's New

Version 0.81:
    The NEC TL card only models an ideal lossless transmission line. cocoaNEC now lets you use more realistic coax and twin-lead models by modeling a transmission line with the admittance matrix of a NEC NT (network) card. For modeling common mode current, the shield of a coax cable can also be included.


Mac OS X 10.6 or later
