[TowerTalk] antenna impedance anomaly (UNDO)

It has finally dawned on me of my mistake in equating the phase angle 
reported by EZNEC for the whole element was taken from the source data 
report and is the phase angle for the impedance i.e voltage and current, 
However the phase angle reported by EZNEC in the table of currents 
apparently is a different type of phase angle.  I cannot find in the EZNEC 
manual any explanation of what the phase angle in the current table refers 
to.
******
The  phase of the current is relative to the same reference as the voltage excitation of the antenna. For instance if the NEC EX card specified 1,0 for the excitation, that would be zero degrees.  
******
I assume that in order to define a gain pattern, all current phase angles 
in all segments and all wires must have a common reference.  Perhaps I 
should pursue the answer in some other forum but if any Towertalkians can 
help I will appreciate it.
