I did not make that claim.

Pits from the lightning strikes are evidence that the voltage gradient
is high between the coil and the Faraday screen. The second coil is
clean, not pitted.

I explained the operation of a Faraday screen earlier but was
misunderstood so I`ll quote a professional writer and consulting
engineer, B. Whitfield Griffith, Jr. who writes on page 246 of
"Radio-Electronic Transmission Fundamentals":

"It is often desirable and practical to allow one type of coupling
between circuits and eliminate the other. Figure 28-1, for instance,
shows two coils which are coupled but have a special type of shielding
between them that causes the coupling to be purely inductive and not
capacitive, This shield consists of an array of parallel wires which are
grounded at one end only. The lines of electric force from the coils
terminate on these grounded wires, so that there are no electric lines
of force passing from one coil to the other and hence no capacitive
coupling. On the other hand, since the wires do not form closed loops,
there is no circulating current in the shield and therefore nothing to
stop the penetration of the shield by the magnetic field. This type of
shield has long been known as a Faraday screen. It is important that the
capacitive coupling be eliminated in many cases, since it has the
characteristics of a high-pass filter, tending to accentuate the
harmonic content of the transmitted signal."

I never tried it, but I`d bet that someone has measured the radiated
harmonics both with and without the Faraday screens inplace. That would
prove effectiveness.

Short-circuiting the open ends of the Faraday screen wires would kill
transfer of the signal between primary and secondary of the transformer,
and the transmitter would likely complain.
