I ran some EZNEC simulations of ~1/4 wave monopoles over perfect
ground. According to the program, if you shorten the monopole just
enough to achieve resonance, the impedance is 36.0 ohms, independent
of diameter for a range of diameters from 0.00001 to .02 wavelengths.
This doesn't agree with any textbooks on the subject that I have read.
Are the textbooks all wrong, or is this an NEC-2 limitation (or did I
goof up somewhere). I tried various numbers of segments and it
doesn't seem to affect the results.
