In general, decent NEC models of different antennas should be
intercomparable. "decent" being the operative word.. it takes a fair
amount of skill and work to generate good models, especially if there
are tapered elements, traps, or lumped components. The other thing
that will definitely be an issue for a model is anything where the
feedline or other stuff is part of the antenna, whether deliberately or not.
But, for comparisons of run of the mill Yagi-Uda arrays, with
attention to segmentation and such, one should be able to get
comparative data within 1/2 dB or so.
