At least in Version 5.1 of 4NEC2, which I have, the only thing it will do 
is to generate an INPUT file for VOACAP et al, which are the programs 
available under the ITSHF rubric.  That's quite a lot, but falls short of 
the sort of integration Jim seeks.  Arie's note says that the other things 
are in work.  MultiNEC already has the ability to generate input files from 
real antennas and link to VOACAP/VOAAREA on the fly.  Very cool.

At the risk of self-horn-blowing, people might want to take a look at my 
Dayton 2003 presentation which summarizes the state-of-the-art in 
relatively low-cost or free antenna evaluation software -- specifically, 
HFTA, MultiNEC, 4NEC2 and VOACAP.  It can be viewed on line (high-speed 
connection recommended) or downloaded as a Powerpoint file from 
www.pvrc.org -- look under "News" in the bottom half of the home page.  All 
the URLs for downloading this software -- most of it is free -- are in the
