Radio is interesting and still not much is known why electrical oscillations
take off into the air.
A certain voltage and frequency is needed. In the ol' days you needed the
grounding to the crystal set to get a strong signal and still perhaps for
good transmission.
Bearden in a video explained the longitudinal wave generation with
guitar strings that wave sinusoidal but the ends vibrate the instrument.
I wanted to read up on Tesla's experiments and see some of them.
If they were not too big, there is a book based on his demonstration
aslo at this web site:
EXPERIMENTS WITH ALTERNATE CURRENTS OF HIGH POTENTIAL AND HIGH FREQUENCY
Now if you see those diagrams, they don't appear too big.
In his autobiography, his first oscillator coil is pictured and said it produced
two square feet of streamers for an 8 inch coil.
Some of those others I would like to see or read about.
You can read the book at amazon.com
Project Gutenberg had
an online text without the illustrations.
The hardcover book at amazon I sent back due to no illustrations.
