NEC-LIST:Modeling DL6WU VHF Yagis

All:

I found a neat basic program to generate DL6WU yagi designs. I thought I
would model these. I found that the model's resonant frequency was off
quite a bit from the design intention. I'm thinking that it may have
something to do with the boom. The program is quite explicit on the
diameter of the boom, as well as whether the elements are insulated from the
boom, insulated through the boom or attached to the boom. I made no attempt
to model the boom since I have no experience with this.

Does anyone know how to accurately model these types of antennas?
