This thread is of interest to me in that I like many others have antenna
programs in DOS
Now all computors sare sold with Windows XP which has no provision for dos
Now many programs shown on the given page are also written in DOS and
loosely
describe that it is to be used with a 32 bit console program mode. But there
does not seem to be any specifics
about this or where it can be obtained ,which leads me to think of
discarding all the newer window programs
and backtrack to Windows 98.
So for a newcomer it is not all that simple as compatability is not ensured
when one has a computor
that is four years old or newer.
It also begs the question why, as processors become faster ,one backtracks
by using "32 bits".
Thus the thread initiator has to step carefully to ensure that the program
chosen is compatable
and useable with XP program which now appears to be the choice of today, and
not have to tread though a
range of additional interface additions.

What about free versions of the NEC code?

I am interested in modeling a helically wound antenna and so need a lot
of segments.

Thanks.

For free packages, I find the 4nec2 program amongst the most powerful
and easy to use. You can download it from the NEC Archives at
http://www.qsl.net/wb6tpu/swindex.html

It has most, if not all, of the features of many of the commercial
packages plus a few that they don't have. I believe the NEC2 engine
underlying the gui is set up to handle up to 11,000 segments.
