Default EzNEC Antenna Voltages

EZNEC4 computes the antenna currents. Knowing the voltages would be
interesting. Unlike the feeder line where the voltage or current are
easily determined from the characteristic impedance, the line
parameters, and the terminating impedance, how do you
determine the antenna voltages? First blush says, uh, 377ohms relates
the voltages and current, but that's in free space. The antenna has
radiation, inductive, and electric fields (well, the radiation field
is actually the transverse electric field component), so how does one
go about getting the voltage as a function of antenna position (EZNEC
current). I'm sure the answer is obvious but I'd appreciate
confirmation (of an answer and my clouded intellect).
Thanks.
