Summary
[edit]
| Description |
English: The antenna mast and transmitter building of Germany's first high power radio transmitter, Nauen Transmitter Station, Nauen, Germany, just after it was built in 1906. Inside the building was a 10 kW spark gap radiotelegraphy transmitter powered by a 25 kW generator turned by an oil engine. This drives an umbrella antenna consisting of a 300 ft. steel mast with a capacitive topload of 162 cables radiating from the top. The station had a reception range of about 3500 kilometers (2300 miles) |
