Whereas such antenna predictors seem to feature in amateur usage,
does anyone, anywhere, in the world of amateur radio have an
understanding of the underlying principles involved in
predicting the performance of antennae, or have we all,
regrettably, become indistinguishable from
consumerist CBers or beginner licensees?

4NEC2 and EZNEC are* just a fancy front and back ends for NEC2 (and
NEC4) Engines.

Thanks for the heads up, Brian, but a quick glance suggests that some
revision might be necessary of my 3rd year uni textbook, "Fields and
Waves in Communications Electronics" by Ramo, Whinnery and Van Duzer.

ISTR it to be an excellent book explaining complicated things in words
of one syllable, but 46 years down the line, I might have a more
romantic memory of it in reality :-)



I've got mine here. We used to call it Ramo Whinnery and Bamboozle. From
the inscription in the fly leaf, it looks like I used it in 3rd year
too. Mine has one of the equations printed upside down, which threw me a
bit.
