I've seen some big, dense books on antenna design.
When somebody says that you get antenna gain because
of "capacitive coupling", it's equivalent to somebody
saying that a car-engine works because of "force".
What about the other 99.9% of the story??????
Didn't anybody think of controlling for other variables,
such as the fact that on most people, their chin is
_higher_ than their pants-pocket, so that radiation from
that location has a better shot at clearing obstacles?
