After completion of the new wood tower, which was 156 metres high without the arms carrying the antenna (with these arms its height amounted to 163 metres), the second wood tower was dismantled and rebuilt in 1935 at Nuremberg-Kleinreuth, where it served until 1961 as a transmission tower for medium wave. The wood tower at Ismaning carried a dipole antenna, whose point of feeding was at 120 metres height. From this point of feeding, several wires ran to the arms on the tower top and to fastening spots at a height of 80 metres. At this height a differential transformer was installed in a small housing inside the tower; its task was to prevent the drain of the radiated high frequency over the feeder. This antenna, developed by the company Lorenz, was called "Höhendipol". It was one for the transmitter frequency of 740 kHz, which was used from 1934 to 1950, optimized fading-reducing transmitting antenna. However, according to the wave plan of Copenhagen, which required directional radiation at night times, it could only be used during daylight hours after 1950.
