Stolp radio transmitter was a broadcasting station close to Rathsdamnitz, Germany ( since 1945: Dębnica Kaszubska, Poland) southeast of Stolp, Germany (since 1945 Słupsk, Poland). The facility, which went in service on December 1, 1938 was not just used for broadcasting, but also for clarifying the question, if it is possible to build a directional antenna with skywave-suppressing characteristics by suitable feeding of single antenna of an antenna group. Herefore a group of 10 antennas arranged on a circle with 1 kilometres diameter around a central antenna was planned. At time of inauguration just the central antenna was completed. It consisted of a 50 metres high, free-standing wooden tower, in which a vertical wire, which worked as antenna was installed. Until July 1939 six further towers of the same type were built on a circle with 150 metres diameter around the central antenna tower. All these towers were the tallest wooden lattice towers with triangular cross section ever built in Germany. The antennas were fed through an underground cable, which run from the transmitter building, 180 metres away from the central tower to the central tower, where a distributor for the transmission power was installed. From this distributor, overhead single-wire lines mounted on 4 metres high wooden poles run to the antenna towers on the circle for feeding their antennas with the transmission power. In 1940 south of the transmission building a 50 metres tall guyed mast radiator, which was manufactured by Jucho, was erected. The facility survived World War II and was shortly after World War II used to broadcast the program of the Russian military broadcaster "Radio Volga". However, in 1955 the facility was completely demolished after the removal of all technical equipment. External links
