It was early recognized that the radiusof comnumication was greatly extended by increasing the capacity ofthe aerial; which fact has led to the employment of multiple-wireantennae. Figs. 37, 38, 39, and 40, show some of the commonerforms, conditions usually determining the choice. It was found… … Fig. 36. Poulsen Direct-Current Method ofGenerating Oscillations 149 56 WIRELESS TELEGRAPHY is apparent why in many of the aerials the individual wires areseparated to comparatively great distances. It is of extreme importance that the upper end of suspendedradiator wires should be exceptionally…
