I am not fluent in English. So try to understand.
The electrons (they have mass and inertia) colect in one end and next
disappear. It is the one cycle. Next they travel to the other end. It
takes time. So in space are send the two signals.(in one your cycle).
In the same time 9Your cycle) the current flow to and fro.
In unverified EM the current cause the spherical wave. In reality the
ends.
Only Your simple measurements can verify it.

i have made my simple measurements, the frequency is not doubled by the
antenna.

You are to speedy. Look at the original Hertz experiment:
http://people.seas.harvard.edu/~jone...Hertz_exp.html

There is: "According to theory, if electromagnetic waves were spreading
from
the oscillator sparks, they would induce a current in the loop that would
send sparks across the gap"

In EM waves are produced by the current (oscllator sparks in the Hertz
apparatus). One cycle is completed when the current flow to and fro.

But there is possible the other theory. Electric waves are spreading from
the ends (plates or big balls in Hertz apparatus). Now we know that
electrons have mass and are compressible. So at the ends appear and
disappear the huge charges. In that case an electric impulse is send when
the current flows to (from one end) , and the next when the current flows
fro (from the other end). So in one EM cycle are the two electric cycles.
So the frequency is not doubled. The electric is twice more.

Does your measurements distinguish radiation from the spakrks from that
from the plates?

I'm sorry, but i don't have a spark transmitter, those have been rather
illegal for many years because of the extreme bandwidth and noise they
generate. I use a nice clean sine wave so there is no harmonic generated.
if you use a spark generator there will be many harmonics, but they come
from the waveform being generated.
