The traditional wisdom that elevated radials are generally significantly

Hi Owen,
As Reggie would have pointed out at this juncture, tuning of radials
in very close proximity to the ground would have been an exercise in
futility (that is, expecting a sharp resonance as would be evidenced
in elevated radials). As was his wont, his description of radials as
lossy transmission lines would have held sway in this analysis.
This, of course, is contingent upon my having understood the
implication of the quoted text above relating to tuning radials near
the ground (instead of on high).
