English: Reconstruction of the directional antenna used in the discovery of radio emission from space by Karl Guthe Jansky at Bell Telephone Laboratories Holmdel, New Jersy, in 1932, which began the field of radio astronomy. It is an 8 element Bruce array (a type of curtain array) resonant at 14 MHz, consisting of 8 wire dipoles in front of a wire screen reflector. Now at National Radio Astronomy Observatory in Green Bank, West Virginia.
