We know that the forward

by only 2 degrees, end to end. Therefore, contrary to
what Roy asserted, the total current does NOT have the
same rotational speed as its components.

I'm bothering to respond to Cecil's rantings and diversions only because
he's using EZNEC to support his junk science.

All voltages, currents, E and H fields reported by EZNEC have the same
(phasor) "rotational speed", which is 2 * pi * f radians/second where f
is the frequency chosen by the user. Nothing which EZNEC reports alters
this. The fact that the phase angle of the current is nearly constant
over the length of a dipole indicates that the phase angles of the
elements of current along the wire are nearly the same. This means only
that at any instant, the phasors representing currents along the line
are all pointing in nearly the same direction. All are rotating at
exactly the speed given above.

If one wants to break the current into "components", that is, any number
of currents which linearly sum to produce the total current, the phasors
representing all those components will also rotate at the same rate.

I'd suggest that Cecil go back and review basic phasor theory, but I
know that learning isn't the objective here. It's to sustain the
argument at all costs and any level of banality until everyone else
tires and leaves.
