Abstract
286,354. Rees Mace Manufacturing Co., Ltd., and Hoisington, W. F. Dec. 1, 1926. Aerials; receiving-sets, construction of. - A frame aerial comprises a plurality of sections 1, 2 wound in spaced relation on a support, which may be a portable wireless receiving set and provided with switching means such that all the sections may be connected in series or part of them only, and such that when only one section &c. or portion thereof is effective the other section is shortcircuited. The Figure shows a switch 8 adapted to effect these operations and a jack 10 to enable an external earth and aerial to be used. In a modification (Fig 1, not shown) two double-pole double-throw switches are employed to effect the switching. The aerial is preferably employed with the wireless receiving set described in Specification 286,353, which comprises a high frequency amplifier enclosed in a shield, a detector, and a separate shield for the electromagnetic actuator of the loud speaker which is mounted in a frame inside the aerial.
