The facility includes two transmission towers. The old tower was built between 1936 and 1937. It is 53 metres high (including its antenna mast, which no longer exists, it had a height of 95 metres) and has an observation deck, which can be reached by elevator. This tower was intended to be used after 1939 for TV transmissions to central Germany, but due to the beginning of World War II, it was transformed into a radar facility. Unlike most modern TV towers, the old tower looks like a block of flats with a square cross section. The arrangement of the windows in the observation deck is similar to those in the restaurant in the Radio tower Berlin.
In 1973 a new TV tower was built on Brocken. This 123-meter, freestanding steel-tube tower stands on three legs, which hold shafts for cable and stairways for personnel access. Above the legs are three decks for directional radio transmission aerials. The new TV tower is not accessible to the public.
While Germany was divided into East and West, the Brocken transmitter was used for TV and FM-transmissions, even though it lay in the restricted area of the east-west frontier (on the Eastern Side). Its location so close to the border enabled it to be received in parts of the West.
The Brocken Transmitter is property of Deutsche Telekom.
