That is exactly what I'm using Reg, and why I"m puzzled. I'm getting rising
feedpoint impedance with increasing numbers of radials. The 2:1 bandwidth is
getting narrower, as it should, but what accounts for the increasing
feedpoint impedance? MFJ-269 antenna analyzer is what generated the table I
posted earlier.

Very strange?

I'm a bit confused by the rising feedpoint impedance with increasing

=============================

SWR increases the further the impedance, either HIGHER or LOWER,
departs from 50 ohms.

The only way to measure antenna input impedance is by means of an
impedance bridge. Try one of the small antenna analysers.
