After reading Josh Carter's blog on modeling the Buddipole in cocoaNEC, I took it upon myself to modify his initial source as an exercise in learning the cocoaNEC NC language. Below is a link to my NC source code for a Buddipole configured as a dipole, customizable with arms, coils, standard, and long whips. Enjoy.
