We do not have the both. But we have the Luxembourg effect. Each dipole
antena radiate two times the applied frequency, The pulses from the ends
are 180 degrees apart.

So then, Szczepan, should transmissions using such antennas, and
expecting to be received on frequency "X" transmit on frequency "X" /
2 ? Note that such is not the reality.

It happened in 1930. The Luxembourg LW were received on MW radio sets.

Some low-level radiation from the transmit antenna may exist at twice
the carrier frequency, but in almost all cases it arises from
insufficient suppression of the 2nd harmonic of, and in the
transmitter.

The Luxembourg effect is only possible if the both ends of the dipole are
"visible". The mast was on the tip top.

And in NO case is it produced as you describe above.

It is easy to check. Now no vertical LW masts. But everybody has a
horizontal dipole.
