Diagram of wire antenna at Nauen radio station, Nauen, Germany
Summary
[edit]
| Description |
English: Diagram of the huge wire longwave flattop antenna built in 1912 at Nauen radio station, Germany's most powerful international radiotelegraphy station, in Nauen, Germany. This was driven by a new 100 kW W:spark gap transmitter, the most powerful radio transmitter in the world at the time, to transmit telegram traffic between Germany and its African colony Togoland and the Americas. It consists of 20 horizontal cables, in two groups of 10, supported on 5 120 meters (390 ft) steel towers (T), fed by vertical cables at the transmitter building. The directive antenna was pointed at Germany's colony Togoland in south-west Africa. It could also communicate with North and South America, in spite of the fact that the Americas were located in the worst possible direction, in the null of the antenna's radiation pattern. |
