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 EN 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".
