Hello Steven,

Now that you mention it, I have seen data sets for antennas
at anti-resonance which display the negative reactance
slope. I expect Geyi's assumptions don't fit this case.
But where does the |X|/w term in your expression come from?

Z=R+jX, dZ/dw=dR/dw+jdX/dw, so

|dZ/dw|=sqrt[(dR/dw)^2+(dX/dw)^2]

No?

Regards,
Doug
