The simplest dipole is made from a transmission cable. It is enough to
stretch the wires in the oppsite directions (like arms).
There no junctions.

Which part is the hottest?:
-Transmission cable,
-The first part of the arm,
-The end of the arm.

i know better than whatever you think you understand of tesla's work,
and also have at least 60 years of research after he died to support
it. the first part of the arm is hottest, just like the center part
of the dipole that is not heated due to a bad connection... maybe you
make bad connections to dipoles, i don't!

Michaels answer was the best: "Aside from analysis, has anyone measured this
effect?

Is it to be expected in highly efficent antennas, or just inneficient
ones in which there is substantial heating already?

I have found that ice (hoar-frost) and rain do not disturbs radiating. But
the ice-water strongly. The ice-water is in a moment when the hoar-frost is
melting and in the pores is water (normally is air).

It is agreement with: " "In fact, most dipolar solids exhibit extremely
small dielectric losses since W tends to be extremely large. Water-free ice,
for example does not heat significantly under microwave irradiation."

I have found also that the temperature is measured for antennas for
annimals. The temperature rise must be below 15C. Of course they know the
details.

So no additional questions from me.
