Cecil is so good at quoting that he should have no problem with

arc-cosine analysis.



"It is generally assumed that the current distribution of an
infinitesimally thin antenna is sinusoidal, ..."

Simply look at Kraus' graph in Figure 14-2. A sinusoid with
current amplitude equal to 1.0 at the center and current
amplitude equal to zero at the end is obviously a cosine
wave. Since the magnitude varies from 1.0 at the center to
zero at the end, taking the arc-cosine of the magnitude
yields the distance from the center in degrees.


The key words are "infinitesimally thin," and "generally assumed."
With you, Cecil those words become just "thin," and "dead certain."
I'm glad you clarified that for us. I was beginning to wonder about
Kraus. Now I know it's just Kraus' message suffering from Cecil distortion.
