We may say that the transmitting aerial, the receiving aerial and the earth form one gigantic Hertz oscillator.
First, he would need an oscillator to produce the complex pulse.
Finally, where four or five oscillator tubes are connected in parallel proportionately greater distances can be covered.
The oscillator, though simple in its construction, is one of the most wonderful of all electrical devices.
The antenna plays the part of one of the metal plates in the Hertz oscillator.
Think of the tower of the oscillator as a tube, and of the great mushroom-shaped top of the plant as another ball.
This transformer will supply current for one or two 50-watt oscillator tubes and it costs about $40.00.
Then the moment we start the oscillator we have the same effect in both circuits.
Among them was one in which he attached to his oscillator a ring magnet with a small air gap between the poles.
This is to prevent the oscillator from exciting lateral rf resonances.
