I originally asked about the availability of EZNEC modeling files. I was referred to a couple of Cebik's pages: http://www.cebik.com/aids.html http://www.cebik.com/models.html and then to http://www.antennex.com/Sshack/model.htm Between them, I found tons of models for reasonable prices. 73, Dick -- Dick Flanagan W6OLD OOTC CFII Minden, Nevada Visit http://www.cvrc.net
