Abstract : The construction of a new 78-m high, 500-t tow-array antenna in Nauen near Berlin for 'Radio-DDR' broadcasting is briefly reported. The main lobe direction is controllable in both vertical and horizontal planes; the two arrays from a 50 degree angle. It takes six minutes to set the antenna in any specified direction by automatic, programmed control. The antenna is supplied via a coaxial aluminum waveguide which has a pulsation of 1.1, an attenuation of 0.15 db per 100m, and a frequency of 30 Mc. (Author)
