Repeating what was previously posted. The following model treats a 1 meter
(perfect conductor) monopole, of 0.814 mm diameter, connected to a perfectly
conducting ground. I have applied a vertically polarized incident E-field
of 1 V/m (peak). The base of the antenna is loaded with the antennas
complex conjugate of 1.747 + j823.796. NEC2 computes the current through
the load ast 0.2863 Amps (peak), which is 0.5001 V peak. This appears to
agree with Reg's program.
. . .


Possibly someone can point out if there are any errors in the following
code:

CM 1 Meter Vertical
CE
GW 1 50 0 0 1 0 0 0 0.000814
GS 0 0 1
GE 1
GN 1
EX 1 1 1 0 90 0 0 1 1 1
LD 4 1 50 50 1.747 823.796
FR 0 3 0 0 19.9 0.1
RP 0 181 1 1000 -90 90 1.00000 1.00000

You've specified a plane wave of 1 V/m peak arriving in a horizontal
direction over a ground plane. This results in a field strength of 2 V/m
peak at the antenna. For more information about this, look at my
postings over the last couple of weeks on the thread "Antenna reception
theory".
