If you are using tapper, then you likely have two wires connected for the yagi driven element. Try just using one 1/2 wave long wire with the T-match, and average your tapper results idea a little.

You will also have to drop any idea for using an attached mast too. However, I find on my models that the addition of elimination of the mast seems to make little if any difference in any of the antenna details I've noticed.

IMO, the reason is, Eznec cannot make wire connections anywhere but at the junction of wires. Except for the fact that I see my S4 and your .82 model showing different phase than my New Vector and the Sigma4 with longer radials, this issue might be the same problem I am seeing with my models phase differences, and you're seeing using Eznec for your yagi radiator.

I think you will then see the balance and the in phase relationship you're looking for in the pattern, whether you have phase on or off. Try switching the phase and watch the currents indicator remain about the same.

If you find this idea true, then you may want to talk to Roy about the issue. It is just a guess, but these issues may be connected.
