No, the topic was antenna radiating all the power fed to them.

Specifically, doing it efficiently. Just being hard to match.

Never mind the other bits, beginning to look like old ground already today.
What I might be missing about my comment on some body at some temperature
being limited in its rate of dissipation might be flawed anyway. Never mind
the risk of confusion between an antenna's radiation resistance and what I'm
trying to get at, there's another angle to this...

Am I wrong? Could it be that just as an antenna is efficient regardless of
size, IF you can feed it all the energy you're trying to transmit, is it also
true that regardless of size, that hot body will also equally transmit all
its heat? In other words, is the 'limit' analogous to matching, as in getting
the heat from the bulk volume out to its surface?

I'm hoping that answer(s) to this one might help solve a heap of confusion
for me..
