4nec2 predicts an impedance of between 10 and 20 ohms depending of the
assumed values of R in the impedance loads. The actual antenna measures
36 Ohms at the feed.

The question is: What is the basis of the difference between predicted
and measured values?

Does 4nec2 include the ground losses in the feedpoint impedance?

4nec2 does have Sommerfeld/Norton. Incidentally my NEC2 gives 15.7 + j
110.6. The 15.8 + j133 comes from NEC 4.1.
