With its novel directional antenna, WOR produces a maximum field strength toward both New York and Philadelphia while limiting radiation in the direction of the ocean and sparsely populated areas. Radiation distribution measurements are given. The layout of the station and the unique arrangements for lighting, heating, and ventilation of the building are described. A serious attempt has been made to design and operate the equipment for a performance consistent with advanced ideas of high fidelity. Measurements from microphone to antenna of distortion, noise, and frequency response are presented.
