Default "Balancing" versus "cancelling"

Looking thru various antenna pages on the web and I continually find
reference
to inductance CANCELLING capacitance.
The operative word should be BALANCING and the difference is important
.. In all cases the capapicitor is still there and operative
as is the inductance.One cannot say they are cancelled so they can be
disregarded.
You cannot make either of them inoperative or of no consequence even
in the case where a clockwise
wound inductance is in series with a counterclockwise inductance since
by definition
both are energy containers. When you have a resistive impedance for
a full wavelength without a reactive component per se what it means is
that the energy contained in each of the energy containers are equal
thus allowing for symetry as in a loss less pendulum. If on does not
have a full wave length you can still have equal energy sinks but
their release of energy is not synonymous with each other thus there
is no symetry.
So concentrate on the word "balance" or "equilibrium" when maximum
efficiency is required.
