Thank you very much for the results on 8 radials.

As expected, it seems that for small numbers of radials the resonance
effects are begining to appear again.

I have ideas as to why this should happen.

Hi Reggie,

You "should" if you had read Brown, Lewis, and Epstein. They
discussed this nearly 70 years ago. Radial3 appears to miss that mark
by various amounts ranging from 6 to 60dB.

It's to do with the geometry of the system

Duh. And the problem you injected in that you abstract one wire to
many.

and the fact that the ends of the radials are
not terminated with true open-circuits when calculating input
impedance. ( As is assumed by program Radial3.)

Given Hassan's and other's reports of the outrageous departures
between Radial3 and BLE/NEC4 (with your concurrence):
But please keep up the good work with NEC4 in which I have great
confidence.
there are at least two of us who find your contradictions would
warrant another fling of chalk off your noggin from Lord Kelvin.
