Here is the screen to add a source:

The % is anything from 0 - 100% and then Eznec places the source in a calculated segment, but physically...the red "O" typically shows up at or near the middle of the segment. This function is limiting if you want the source at the junction of the wires...so then you can use the split feature noted in the last field in the source screen captions "type". Just click on the field and a window with 4 choices pops up, V or I, or SV or SI for split. I think all selections are for voltage or current.
I've read somewhere that the limitation on taper only applies to Nec2 and not on Nec4, and has nothing to do with Eznec, but I could have misunderstood. I'll have to look this up and get back. Taper will does not stop one from adding the feature to your model...but Eznec/Nec2 has difficulty producing accurate results. That said however, it could be taper produces a difference, but as I tend to see in other issues about antennas...the difference is usually very small. I will have to do some more specific comparison models to remind me what I've already tested.
Rather than use a lot of words trying to describe how Eznec makes a loop, here is an image of the Hoop feature used to make a hoop, and put it anywhere on the model you wish automatically and in a flash. This too is a powerful feature...that in the beginning I had to try and do by hand, one wire at a time. This process was not easy even when trying to make 4 radials attached to the base of a radiator.

With a little fiddling around...this became easy to use right quick. I know some probably marveled at the idea that this old man made all the wire descriptions for the Sigma4, for example, and I took credit for it, but in truth Eznec does it all for you.
This I call slick, and that is why I think Eznec is very user friendly and, within reason, can be very accurate if you understand the limitations.
These are the type of features we can thank Roy Lewallen for designing.
