Judging by description, I would guess that there wasn't much difference.

The feedpoint of the radiator alone is 35-j185. The impedance of the loading
toroid is 0.6+j193. Assuming perfect predictability, that gives the antenna
system a feedpoint impedance of 35.6+j8, i.e. it is *longer* than resonant.
That moves the current maximum point inside the toroid making the current
in and out even closer to equal. If a coil is installed at a current maximum
point or a current minimum point, the current in and out will be the same.
If a coil is installed at a place where the slope of the current envelope
is positive, the current will actually increase through the coil.
