What value coil does Kraus recommend, Cecil, for, say, a
pair of forty meter dipoles to make them do what you want
at forty meters?

It's a textbook, not a cookbook, so he doesn't recommend a
specific "value". The requirement is that the coil be self-
resonant at the operating frequency. Quoting Kraus: "Here the
(1/2WL) elements present a high impedance to the coil which
may be resonated without an external capacitance due to its
distributed capacitance." He says a 2-element array of 1/2WL
elements has a gain of 3.8 dBi, a 3-element array a gain of
5.3 dBi, and a 4-element array a gain of 6.4 dBi.

So he didn't give an analysis, but just wrote that a self-resonant
coil would do the job. Thanks, Cecil.
