Is it something wrong if a visitors asks about something?

if you ask then you would be expecting an answer and learn from that answer.
you have ignored the responses you have received and kept going back to your
own theories based on analogies that don't fit. if you really want to learn
then read and accept the answers you have received.

The question was: "It seems that at long distances should appear the
phenomenon of frequency
doubling.
Is such?"
S*

Till today was only one Yes (Brian Howie). The rest were No.
Today Dr. Barry L. Ornitz wrote: "Nowhere in all of the respected
literature will you find frequency
doubling caused by the two ends of a dipole."

So now I know what I want. Do you agree with Dr.?

yes, i agree, no doubling by dipole and none related to distance.

The superposition of coherent waves is a linear function.
Therefore, there is no way for the superposition process
itself to produce harmonics.

For frequency doubling to exist, there must be a nonlinear
process. The question is: Does any nonlinear process exist
between the linear transmitting antenna and the linear
receiving antenna?

I once heard a pile of tin cans talking to me. Turns out
some rusted junction in the pile of cans was detecting
the FM from the local radio station. That was a non-linear
process. Lucille Ball is reported to have picked up Japanese
CW signals through the fillings in her teeth, again a non-
linear process.

But the dipole has the two independent sources on the two ends. The waves
from them are "coupled". We can say "polarised" but it not means that radio
waves are tranversal.

Forget nonlinear process. In emmiting antenna the one current cycle produce
the two spherical waves from the ends (of course not in phase). So equipment
is "polarised" not the waves.
It is most interesting that at very short distances the polarisation works
and the frequency is not twice more.

All are like coherer. The first detector of the radio waves.

The "sources" of radiation on the two ends of a dipole
are not independent. There are coherent with the single
source. There is no way to superpose two coherent waves
to get a doubling of frequency. According to the math
model, all one gets is single-frequency interference.
