When a car body is not available to provide the "other half" of the antenna,
you provide the other half of the dipole.

I wonder if radiated energy would increase measureably if one were to try
to
balance mobile whip antenna by having another whip connected directly to
the
body and tuning it. If it would, how would one locate, size, and tune
it?
