The point I was trying to make on the "Rotational Speed"
thread got lost in semantics so here goes again.

Given - a 75m dipole modeled by EZNEC with 90 segments
in each leg of the dipole. 90 segments was chosen
to correspond to the number of degrees from the
feedpoint. Illustrating 1/2 of the dipole with
0 ohm loads at the following segments:

FP--------23--------46--------68--------90

EZNEC reports the following results:

Feedpoint current: 1 amp at 0 deg

Current at seg 23: 0.9281 amp at -1.06 deg

Current at seg 46: 0.7154 amp at -1.78 deg

Current at seg 68: 0.4049 amp at -2.31 deg

Current at seg 90: 0.0122 amp at -2.76 deg

Since the segment numbers correspond to the
number of degrees, it's obvious that the
segment numbers correspond to the expected
phase shift in the traveling waves.

Question: Assuming the current reported by
EZNEC is a ~cosine function, how does one use
that current to determine the traveling wave
phase shift in the wire?

What is the current phase relative to. The feedpoint , the voltage in that
segment? As I have read this thread there seems to be some confusion on
this point.
