Modeling a TH7 will be difficult in any event, due to the need for
exact component specifications in the traps. It would be better to use
an existing model for a non trapped beam of the same number of
elements along with the curtain, a variant of the antenna for each
band. Getting the curtain right will be the issue.
Any of the NEC-2 based programs should do nicely.
See http://www.cebik.com/nec.html for W4RNL's excellent discussion of
NEC possibilities.
