[TowerTalk] station grounding question

Thus, improving the ground system doesn't reduce ground losses but 
heats up the ground more (????????) but at the same time allows the 
member to radiate more.

What is wrong with this thinking?

The greatest ground losses are in the near field directly
under the vertical element...  Increasing the radial field screens
the ground from the RF with more efficiency... A perfect radial field
would be an infinite metal sheet, at which point the
ground losses will be zero due to 100% shielding...  Ergo,
improving the radial field does not heat the ground more than 
a poor radial field...
