I can`t blame them because I wrote without consulting them first.

Terman does in fact say about what I said. I haven`t checked with Kraus
yet. In his 1955 edition on page 921 Terman writes:
"The second possible way to achieve broad-band characteristics consists
in starting with a resonant antenna (as opposed to a rhombic for
example), but so proportioning this antenna as to minimize resonance
effects. Thus a resonant antenna employing a thin wire is equivalent to
a moderately high Q system and so has a relatively narrow frequency
band.
However, if the diameter of the antenna is made large, the effective Q
is very substantially reduced with resulting increase in bandwidth."
