I've found a definite improvement in distance when sticking next to chin
versus aiming at the car. Why doesn't the simple act of holding the
remote in your hand cause this "capactivite coupling"? Why does
pressing it to some other part of your body improve the effective range?

My BS meter is pretty much pegged.
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?
