Abstract :
A closed 3-meter square loop of 16 turns of wire, hung about 1.5 meters from the ground, was used for long distance reception with an oscillating audion. Daylight overland reception from stations as distant as 3,000 miles (4,800 kilometers) was regularly accomplished. A combination of two similar loops was also employed, and considerably increased the directional selectivity. The inherent directional qualities of these receivers were utilized in the reduction of strays and interference.
