NEC-LIST: Antenna simulation program

Dear,
having done some antenna simulation in the past with YO and AO by K6STI,
mainly on ham-antennas, I've recently been asked to model basic cellular
antennas (over the 900MHz to 2200MHz spectrum) against their environment.
Nowadays, the multiple radiators in these antennas are mainly crosspolar
(+/-45°) over a reflector plane.
The goal is to put in the antennas'vicinity some metalwork (other antennas,
etc.) which could be modelled by using wire elements. Usually, however, this
results in the program running out of segments with the programs mentioned
above. (=non-pro version)

Is there any kind of existing (non-) commmercial software running under
Windows 2000 that would fill the gap?
A to draw up some basic crosspolar antenna types
B to use these antenna types in a reflective environment

Thanks for any feedback!
