radiative energy, another invention of Tesla!

[dedeleco]

Hertz in 1886 and 1887 made the first this type of experiment, oscillator spark gap with balls as resonator and resonator receiver tuned to the same frequency which can be almost identical to the transmitter circuit:

almost identical to the geometric level with tuned ball resonators, except that it did not have the fluorescent tube or the transistors to replace the spark gap !!

It was more difficult for him without these modern means.
With his editing he showed that these were transverse waves at long distances from the wavelength.

Here it is about short distances on this video, and the coupling is not radiative but inductive and electrostatic usual and therefore does not prove at all the longitudinal waves which have no experimental evidence at long distance !!

Completely eliminating transverse waves is very difficult and well-made shields show no transverse waves.

This type of demos totally lacks scientific rigor and the transverse nature of these waves can be demonstrated as done by Hertz !!

The assembly shown is not an MHz oscillator but between 100 times and 1000 times more like Hertz, given the dimensions.
