Yes. Thank you very much. I had lost track and seemed not to be able to
find the item again.


Those little sticky tabs solve the problem.

The illustration is Figure 23-21 (b). Four in-phase 1/2-wave elements
with phase-reversing coils. Kraus says:
"Here the elements present a high impedance to the coil which may be
resonated without an external capacitance due to its distributed
capacitance. A phase reversal is about 180-degrees.


Thanks Richard, there are apparently still old wives
who believe that a coil cannot reverse the phase of the current
even though a shorted stub can. I'm going to post the current
magnitudes and phases for a number of 3/2WL configurations along
with the gains.
