When talking about the voltage on a certain point in a circuit it must be
stated against which other point it is measured.

When the loading coil is connected to earth at its bottom end and when
voltage is measured also against earth then the voltage at the bottom end of
the coil is zero and at the top it is I times  X;  with I = current in the
coil and
X = inductive reactance of the coil.

Ah. This is one of the great mysteries of loading coils that has always
baffled
me. Does anyone have a good explanation?
