several weeks I could not catch static at the electroscope.
It is obvious antenna insulators catch dirty from the Moscow air and could not keep high static
voltage across itself.
Mihail Lomonosov (1711—1765)
3. Current from the Air
connected to antenna terminal of old radio as usual has ground
potential because almost any old radio has coupling inductor
where one end is connected to antenna and other end is connected
to the ground. BA is placed near 10-15 meters above the ground
where the air has potential compare the ground near + 2,000
Volts. So, from wires of the broom a small ions current is flow.
The more wires in the broom, the more current go in to antenna
wire. The more space occupancy wires of the antenna the more
current go in to the antenna. The more sharpener
are ends of wire of the broom, the more current in the antenna.
So, the current
in the antenna direct depend from:
- Numbers of the wire in the broom;
- Angle between center line and wires;
- Sharpener of the ends of the wire.
Georg Rihman 1711- 1753
