Try my Yagi-design javascript. At least it will give a starting point for you, which you can optimize with YO (the Yagi Optimizer program): http://orrin.freeshell.org/yagiscr.html And give me feedback on what you get. The script will output x,y,z coordinates which you can then input into EZNEC, YO, etc. Orrin wn1z _______________________________________________ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.
