I looked into this, and it appears that NEC-WIN PLUS from Nittany
Scientific has a 9,999 segment limit that would make this easy.  It costs
$150, but that's a lot better than EZNEC PRO, which is the only way to get
more segments within the EZNEC family.  It is also a native Widows program
and has some capabilities, such as programming by equation, that can let
you do some neat tricks like rotating a beam antenna model atop a tower (or
another beam) for simulation of things like a stack pointing in 2 different
directions.

I really think Roy has made a mistake by hobbling his product in this way,
though there may be technical programming reasons for doing so.  When
people were only modeling single antennas, 500 was almost always plenty,
but not for things like you and I want to do.

LB Cebik has a good comparative review of the various programs on his web
site.
