In the "International" edition or 3rd edition of Kraus` "Antennas" on
page 824 in Fig. 23-21(b) is shown a dipole made of (4) 1/2-wave
sections. It uses (2) self-resonant coils. Each coil separates a pair of
1/2-wave radiators so that all four radiators have current flowing in
the same direction through them at the same time.

Richard, that graphic is redrawn on my web page at:

The first two sections of that page are quotes from "Antennas"
by Kraus. The second section illustrates the above antenna.
And I don't think Kraus was using the lumped circuit model for
those coils. :-)
