Abstract
A SUCCESSFUL public demonstration of ultra-short wave television was given on Friday, April 29, at Messrs. Selfridges' stores in Oxford Street, London. The transmitter was situated on the roof of the laboratories of Baird Television, Ltd., in Long Acre, W.C.2, the wave-length used being 6.1 metres. The ultra-short waves have the advantage over medium wave-lengths that they allow television pictures of much finer detail to be transmitted, and provide a reliable local service free from fading and atmospheric disturbances. An interesting feature of the transmission was that although sent out on ultra-short waves, the images could still be received easily by possessors of the ordinary Baird‘ Televisor’ and wireless sets of normal type designed for the present B.B.C. television transmissions. To do this, the only extra apparatus required was an ultra-short wave adaptor, which virtually converts any normal receiver into a super-heterodyne. The demonstration given on April 29 is the first public demonstration of the possibilities of ultra-short wave television to be given anywhere in the world, and marks a further stage in the development of the art.
