The transmitter Aalen is a basic network transmitter of the Südwestrundfunk (SWR) for television and radio.

history
The transmitter location was developed in 1951 by the then Süddeutscher Rundfunk (SDR) to broadcast its FM radio program. Before there was only one radio program on medium wave , the new technology “ VHF radio ” was to be introduced with the Südfunk II program. In the first few years, a steel lattice mast with a height of 40 m was used as the antenna carrier, while the tubular slot antenna that was attached was 20 m long. A new structure was necessary to broadcast the ARD television program, so that today's 80 m high reinforced concrete tower was built between 1956 and 1958, which with the antenna mast reached a total height of 142 m.
The original VHF transmission tower in the immediate vicinity was preserved, the transmission antenna was dismantled in 1984. He will u. a. used as a directional radio mast.
On July 10 and 11, 2008, the existing VHF Band III television antenna was dismantled by helicopter and a new antenna system for DVB-T was installed. Since the new digital UHF television antenna is 3 m shorter than the previous VHF antenna, the height of the tower was reduced from 142 m to 139 m as a result of the replacement. With the start of DVB-T broadcasting on November 5, 2008, analogue television broadcasting in East Württemberg was discontinued at the same time at Braunenberg and Heubach transmitter, as well as at numerous converter locations.
In addition to the Heubach location, the basic network transmitter Aalen also replaced the former TV broadcasting systems at the Geislingen-Oberböhringen , Bad Mergentheim and Hesselberg locations in Bavaria after the switch to DVB-T2 .
Location, range and coverage areas

NN. and is about 2 km as the crow flies from the federal motorway 7 and only about 20 km from the Bavarian border . With a height of 139 m at the top of the antenna mast, the transmission tower reaches a total height of over 861 m above sea level. NN.
Due to the topographically very favorable location, the entire region of East Wuerttemberg , the greater Stuttgart area , the district of Göppingen , the district of Schwäbisch Hall and the district of Donau-Ries are supplied. In addition, large parts of the Alb-Donau district , Middle Franconia , Swabia (Bavaria) and the Allgäu are supplied.
