Inundated Yagi
It is amazing to find an aerial dating back to the sixties in such good condition on a building in such a state of dilapidation. It was probably erected between 1966 and 1971 and served from the Belmont transmitter.
UK VHF main stations tended the be vertically polarised and UHF horizontally polarised allowing such a design as this. For such an aerial to be used, the VHF and UHF transmitters would have to be in the same direction or co-sited. The dual feeders are still present and would have been connected to the separate inputs of a dual standard receiver. The short horizontal elements would have just received BBC-2 (System I) initially while the long rods would be used for BBC-1 and ITV (System A), Later the System A networks were closed and replaced with System I but System A transmissions continued with standards converted signals derived locally at the transmitters until 1982. Although disinvested, this aerial could be used for DTT and DAB.
