The Wireless Age
April 1919 

    For one thing it was found that two loops, the planes of which were perpendicular, were connected to a common receiving apparatus, as in figure 5, the static currents could not be balanced out.   The experiment justified the assumption that electromagnetic waves responsible for static currents are heterogeneously polarized; that is, tha axes of the oscillators producing them assumed all possible angles in space; and the highly damped waves resulting therefrom are propagated in a direction perpendicular to the earth's surface.
     In other words, to the unscientific mind, these static waves may be described as an electric shower which acts upon an aerial, perpendicular to the earth.

     To determine the correctness of the hypothesis that static is propagated vertically and to ascertain if it were possible on this assumption to devise a system whereby the static currents could be balanced out while the signal was retained, Mr. Weagant erected at Belmar, N. J., the aerials and apparatus shown in figure 6. Two closed loops A and B, each consisting of a single turn of wire 400 feet high with a base line of 1,000 feet, were spaced 5,000 feet from center to center.  Two wires, brought from each loop to a receiving station located at the center, were supported on ten-foot poles, 6 feet apart. These leads were connected to the primary coils of a goniometer of the type used in direction finders ; the secondary coil was connected to a sensitive oscillation detector.  It was this apparatus that permitted the reception of transatlantic signals through static interference of great intensity, whereas without it, it was impossible to distinguish the wireless signal.
     The connections to the receiving tuner and detector are shown .in figure 6, where loop A has the loading coils L-1 and L-2, the resistances R-1 and R-2, and the coil,
