insulations: the ice and the wet?

Sometimes are on your dipoles an ice or water.
They should melt/evaporate in the places where are picks of the voltage.
Is it observed?
Are you assuming that because there is high voltage, there is current
induced heating?

Bill Miller calls it "the transverse current". Electrons must displace
perpendicular to the antenna surface in AC.
In insulators are the electric losses.
Voltage does not translate diresctly to heat.

Is a quantum effect current flow, and does heat emit from the process?
If it isn't heat induced, the effect is almost certainly ionization.

In insulated antena are the transverse current and the displacement current.

The all are facts. Should be easy to observe.

Some topics ago somebody analised the antenna temperature.
The end of the dipole should be the hottest.

Have you any observations in this subject?

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?

Is this assuming that the heat if given off is enough to raise the
temperature surrounding th eantenna above 0deg C?
