Why wouldn't the current driving into the base of the second coil create the magnetic field that is out of phase? Since the same current going into the base of one coil would be coming out of the other. Two identically wound coils would have the opposite voltage at the top. Richard did you actually try this with two identical coils or just a magnifier system? Skip if/when you do this please give the results.

I don't think these coils will arc to one another, with any wind direction.
They will both spark, obviously, but won't arc to on another without sharing
a mutual magnetic or a separate magnetic drive to each coil.

Think about it.  A half wave system is just two long 1/4 resonators wound in
the same direction.  However the single primary sees two counter wound
resonators on either side of itself.  The magnetic action is the key to the
phasing.  In a true twin system one item of the four coils has to be counter
wound to its mate.

In a base drive senario there is no magnetically phased coupling from a
driving source as the energy is directly coupled into the second system with
no phased magnetic memory as to where the energy came from.  I have been
there, done that with a magnifier. It didn't seem to work for me.
