Abstract

336,973. Aeonic Radio, Ltd., and Kayley, E. V. July 22, 1929. Undesired signals, eliminating.-A wave-trap is inductively coupled to the frame aerial of a radio receiving-set so as to absorb unwanted signals. The wave-trap comprises a variable condenser 6 and coils 4. 5 one of which is permanently coupled to the frame - aerial 2. A switch may be provided for connecting the terminals of coil 4 either to the rest of the wavetrap, or to aerial and earth terminals for use with an extended aerial. In a third position of the switch, the coil 4 may be unconnected.
