Default antenna impedance - calculated 10 - 20 Ohms - measured 36 Ohms??

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?
