Huh?
The stub produces just as much horizontally polarized radiation as the wire. Run your stub vertical model with an elevation plot, and azimuth angle of 90 degrees. Click FF Tab. Note the magnitude of the horizontal component -- roughly -30 dBi. Then repeat with the experimental model with the single horizontal wire. As I mentioned in my lengthy posting, the radiation from the stub isn't a large part of the overall field, and this certainly shows it. But it's certainly enough to disturb the vertical's current. Exactly the same thing holds for the straight wire. Common mode current is common mode current. No magic, no mysterious phenomena "not accounted for" by EZNEC.
