Default Radiating Efficiency

Frank,

To complete the graphs of Rin + jXin versus length for one radial, I
need data for lengths between 0.5 metres and 2 metres at intervals of
0.2 metres.

Could you oblige please?

The nice smooth graphs I have produced so far are free of
'measurement' errors which could be attributed to your hard, tedious
work.

The uncertainty due to NEC4 is as yet unknown. In the NEC4 model of a
single radial, what is the length of the short bits of radial used to
model it? Alternatively, into what number of short lengths is the
radial under test divided?
