There's a figure at the bottom of
http://www.tpub.com/neets/book10/42.htm that shows current distribution on
an antenna. Is there some book or source that describes how figures B and C
and produced?

I'm guessing that one starts with an open ended transmission line, and looks
at how the E and B fields are distributed along it. Then one peels the open
end back until the two lines are pointing away from one another. One then
ends up with E fields pretty much in a plane directed from one point on one
side of the wire to the similar point on the other wire. Similarly the B
fields encircle each wire. On one side they have a CC direction and the
other a CC direction (looking in the direction of the current).

As a separate item, it would also seem that for a transmission line that is
open ended the current flowing in one wire induces a current to flow in the
opposite direction in the other wire. That is the current flows in the one
wire because it does so by induction rather than it being physically part of
the other wire.
