“ The static effects in the Hertz and Lodge experiments were excessively small, owing to the fact that they were produced in a practically closed coil, the potential being depressed. To obtain the desired difference of potential, there must be an open circuit generator of high potential and of high frequency to enhance the electrostatic effects. ”
