They outline why power lines are excellent RF transmission lines that radiate
only at points of "discontinuity."

And, for those that may wonder: there was a typo in the formula, but the
calculations that follow had been done correctly. (Too bad they used the typo
to do all of their calculations incorrectly...)

I re-ran the antenna models and easily found the gain that the ARRL paper had
documented. (The easiest wa to do that is to run a 3 D model in EZW, then check
the box for a 2D display. It will display the plot of maximum gain). Maybe
they can sign up for the ARRL modeling course.
