it isn't any help to the rest of us when some of the things the theory
ignores become significant. In the case of antennas, practically
everything is significant.

All of the theories I am quoting were developed long before I was
born. Almost every technical explanation starts out with simple
concepts and proceeds to more complex concepts. For the sake of
teaching and understanding simple concepts, the secondary variables
are often ignored for the time being. Thus, every textbook on
transmission lines starts off with an explanation of lossless lines
with perfectly resistive characteristic impedances even though such
lines don't exist in reality.
