Default Current across the antenna loading coil - from scratch

wrote:
An inductance changes the relationship between phase of voltage and
current, NOT current through the inductance from terminal to terminal.


That's true only for a lumped inductance which doesn't exist
in reality.

Yuri again distorts fact. What everyone is saying is there can be a
current change, but it is not caused by standing waves or missing
antenna area. It is caused by displacement current, and so can have a
wide range of change in a given antenna.


In the graphic at:
http://www.qsl.net/w5dxp/test316.GIF
in the right hand configuration the current at the bottom
of the coil is 1.3 amps and the current at the top of the
coil is 2.1 amps.

Your explaination for more current at the top of the coil
than at the bottom is that 0.8 amps of displacement current
is jumping up from earth ground into the side of the coil
and flowing out the top?

Would you please describe that bit of magic in a little more
detail?
