discussion here, is it not?


I see that this question bears on my previous correspondence where
you have failed to attend to that relevance. In fact, my model's 1°
response is only 1.6dB below the peak response at 8° (both of which
are below 10°). That peak response is roughly half a dB below a
perfect ground response at 0°.

Then your NEC analysis is not a _FAR-FIELD_ NEC analysis, as
repeatedly I have referenced in my posts, and even as is shown in your
quote of the same point, above.

I suggest you carefully read and consider what I write as many times
as is necessary in order to avoid such gaffes.

The rest of your post of the date/time quoted above I will dismiss, as
I have already responded to it.
