Abstract

195,051. Marconi's Wireless Telegraph Co., Ltd., (Assignees of Manley, L. L.). March 14, 1922, [Convention date]. Aerials. - A loop antenna, particularly for indoor reception of broadcast signals, comprises a coil 1 mounted on a flexible sheet 2 so that it can be readily folded up. Tappings from the coil 1 may be brought out to terminals 4 on a reinforcing strip 6, and the sheet 2 may be mounted on a spring blind roller which is hinged at 10 to permit adjustment in azimuth. A hcok 16 is provided for keeping the antenna extended when required. In modifications, different types of hinge may be used, and the coil 1 may be connected to terminals on the bracket 9 through the metal caps at the end of the roller.
