Abstract

1498388 Mobile diversity receiver STANDARD TELEPHONES & CABLES Ltd 4 March 1976 8706/76 Heading H4C In a mobile receiver arrangement, switching means 3 controlled by oscillator 5 ensures that one, or other of aerials 1, 2 {ferrite rod type} are alternately connected to the {VHF} radio receiver 4. The arrangement ensures that the response of the receiver to signals radiated by cable 6 is uniform. The polar response of a pair of orthogonal loop antennae is discussed in relation to Figs. 2, 3 (not shown). The oscillator frequency, in the range 5-20 KHz, is outside the audio passband of the receiver.
