Hi Richard,

So in this exception, I would make one compelling correlation to your
own observation. That distortion of the pattern was a product of
non-linear behavior in the characteristic Z of the antenna. That
alone seems to be evident. It happens so frequently that we need
complex tools (NEC) to juggle the outcome.

We have non-linear behavior, distortion, and it didn't demand
harmonics, did it? Such non-linearity AND distortion were in all
likelihood trivial, and yet it was noticeable. Now, if no one
complained about pattern nulls being lost, would the non-linearity go
away? ;-)

Cecil would shrug off 59% worth of distortion to define it linear.
