1.8 m -- Radial Z = 70.17 - j 24.1
1.9 m -- Radial Z = 68.5 - j 19.0
2.0 m -- Radial Z = 67.2 - j 14.2
2.1 m -- Radial Z = 66.2 - j 9.5
2.2 m -- Radial Z = 65.5 - j 5.0
2.3 m -- Radial Z = 65.1 - j 0.6
2.4 m -- Radial Z = 65.0 + j 3.6
2.5 m -- Radial Z = 65.2 + j 7.8
2.6 m -- Radial Z = 65.6 + j 11.7

I can keep going if you think that these are the results
you expected. I am tempted to continue, in steps of
0.1 m, and plotting the results on the Smith Chart.
I expect the data to rapidly spiral to the center of
a chart normalized at 101. 6 ohms.

======================================
Frank,

Very interesting!

I am plotting graphs of R and jX versus length of radial.

Joining up the dots I expect to see shallow sinewaves superimposed on
fairly level mean values.

At present there is a definite shape of curve appearing in the
reactance values while the resistance values are still fairly level.

As length increases I expect to see something similar happening to the
resistance curve which seems to be in between peaks and troughs.

From now on it seems safe for you to increase length in increments of
0.2 metres. There is no danger of missing peaks and troughs in the
curves.

Please keep up the good work.
