Actually, adding a feed line in like that is throwing everything off...

All currents are listed as 0 uA? I wonder if their is a bug somewhere in the software. Its not just this that is wierd, but the antenna data as well, an SWR of 10.1, and an impedance of 5 - j5? I can go on here, 0% efficiency, yet 153% radiation efficiency? I don't use transmission lines at all really so I am not really sure, and haven't seen them used except when it comes to auto-generated stub matching. It is also possible I could have done something wrong, but I don't know what.

That being said, adding a 1/4 wavelength of in this case 50 ohm feed line between a "source" and where the feed line connects to the antenna, or any amount really, shouldn't make any difference as far as current distribution on the antenna.

Unless you were telling me to connect it differently, at which point I missed what you were saying... Unfortunately I am not certain that I can reliable show you anything using transmission lines at this point.
