I thought your present world revolved around 1 wavelength...
Obviously there must be a chink in this armor..

There was a question asked some where with respect to the number of
wavelengths required for optimum
which really I do not know.!

What I do know that equilibrium is the
cornerstone so the magnetic field produced
by the radiator must equal that of n times wavelength.

If you n times a wavelength, the armor will become to
heavy to wear. :/

The Variometer
either extends the strength of the field
or diminishes it such that it is symptomatic of a wavelength which is
in equilibrium and also resonant. at the particular frequency at hand.
If all is at the above there is never a need for a choke or a balun
since with this radiator you never move away from the resonant point
as with a filter.

Hate to break this to you but resonance, SWR, match, etc, ad
nausium have nothing at all to do with the presence or lack of
common mode currents on a feedline.
