Static Elimination by Directional Reception

The author considers the possible origins of static and inclines toward a solar origin. He finds that static comes from all directions, with maximum intensity from above and maximum frequency from the horizon. The probable static wave form is a single highly damped pulse. The author then describes his early work with loop directional receivers, his invention of the so-called "Dieckmann cage," and his early work in static elimination. He gives the three-dimensional reception characteristics of linear antennas, loops, and various combinations of these. The work carried on under his direction at the Otter Cliffs, Maine, receiving station is then described in detail. Highly successful loop-and-antenna combinations were used in static elimination, and these are discussed with numerical results.
