In textbooks must be all theories.
In one chapter light (and radio waves) is like photons, in the next

like EM waves and in next like acoustics.

EM is the only example of transversal waves. So it must be in teaching
program.

But we try to help Peter. He wrote: "I begin to appreciate a comment made
by
a fellow radio amateur and
technician that antenna theory was 15% science and 85% black magic! "

It seems that you are sure that radio waves are transversal. It is
impossible to help you (Maxwell was full of doubts).
May be that somebody consider the Acoustic analogy and the black magic
disappear for him.

maxwell may have been full of doubts, and Einstein wasn't able to see
the experiments that have proven his theories,

Maxwell did EM, Einstein did the photons and somebody else the acoustic
analogy.

but we have seen them
well tested and accepted over the years.

All of that three ( all three are in textbooks) are well tested and accepted
but only in some extend. May be that after some time only one will be fully
accepted. Which one do you designate?

if you think that 85% is
black magic then you have lots of learning to do to fill in that 85% gap in
your knowledge.

I designate the acoustic analogy and do not see any gaps.
They who designate EM or the photons are in constant trouble for more than
100 years.
