Abstract

302,634. Standard Telephones & Cables, Ltd., (Western Electric Co., Inc.). Sept. 19, 1927. Fading, preventing; directive signalling.- A wireless signalling system comprises a plurality of aerial structures, each adapted to receive a differently polarized component of the transmitted signals, and means for combining the components in a receiving device M without previous rectification. The aerial structures are arranged perpendicularly to each other and consist of elements a1, a2, arranged on a parabolic surface about aerials R1, R2. If the aerials are half a wavelength long, to ensure that the components reach the receiver in correct phase the length of transmission lines W1, W, is a multiple of a quarter wavelength plus a multiple of a half wavelength.
