Abstract

149,532. Hollingworth, J. Sept. 5, 1919. Aerials.-An aerial which responds to signals from all directions is formed of three or more loops arranged in more than one plane, consecutive loops being connected in series but wound in opposite directions, like the two halves of a figure eight, as shown for example in Fig. 3. With a number of such loops, signals are received with an intensity independent of their direction.
