Me either since I don't remember anything about "typical

HF+ RF energy move hardly at all. It is akin to tossing
a stone into a still pond - the water molecules (carriers)
move hardly at all except up and down.


They move along the eliptic trajectory. The longitudinal component is large
than the transversal.



Another brou har ensued with the implication was that
both the upward and downward travels of the applied current was on the
same skin deep surfaces! *Very wierd.


Again consider tossing a stone into a still pond. When the
waves reach the shore, they are reflected thus forming
standing waves on the water. Again the water molecules
move primarily up and down, moving hardly at all in the
direction of propagation of the forward and reflected waves.


See above.

You mentioned an article in Radio World about the construction of NEC
Could you send me a copy?
