[Class 40 (v).] Television and like signals on a very high carrier frequency are received at a central station C and distributed on a lower carrier frequency. The high frequency carrier, e.g. 60,000 kilocycles, received on an aerial 1 is changed to 1700 kilocycles by a heterodyne circuit 2 or by detection followed by remodulation. Similarly a second high-frequency received on a second aerial is charged by a circuit 3 to 1600 kilocycles. The signals are distributed by a cable 5 with one of its conductors 6 and an outer shield 8 connected to earth 9. Individual sub-stations G are connected to the cable through a condenser 10 and resistance 11 to prevent detuning by other sub-stations. The required signal is selected by a tuning condenser 12 in the input to a band-pass filter and passed to a reproducer 15. Sound signals are filtered out and applied to a loud-speaker.
