eddy, maybe i am reading it wrong but i take it he was refering to verticals with insufficient radials to constitute a perfect ground and that such an antenna should not be grounded to a conductive mast at the junction of the radials and feedline outer shield,
a no radial endfed or 4 radial vertical groundplane fits that description to me,
some would say i make it read how i want it to read and that may also be true but it is unintentional,
i would hardly compare 4 radials or no radials to the 120 wire ground mounted radial system let alone the perfectly conducting infinate ground no mast and feedline that is often used in antenna models when we see the huge difference between 1/4 1/2 and 5/8waves in the polar plots which dont seem to be born out in real world tests over real ground and typically grounded mast no balun installs,

i dont fully understand it maybe i dont understand it at all but what i did clearly altered the pattern of that a99 in a positive way and fixed the rf problems in the shack,
it is something i will be experimenting with in the future.
