The transmitter Hornisgrinde is a basic network transmitter of the Südwestrundfunk (formerly Südwestfunk ) for radio. It is located on the Hornisgrinde , the highest mountain in the northern Black Forest , at an altitude of 1125 m above sea level. NN . A 206 meter high reinforced concrete transmission tower, which was built from 1971 to 1972, serves as the antenna carrier.
function
The Südwestfunk used the Hornisgrinde from 1951 to broadcast its VHF radio programs and from 1954 also as a transmitter location for the first TV program of the ARD. At that time, two steel lattice masts were used as antenna supports. The current 206 m high reinforced concrete tower was built from 1971 to 1972.
The transmitter on the Hornisgrinde is next to the Stuttgart TV tower the most important transmitter location of the Südwestrundfunk. Numerous other SWR broadcasting systems receive the programs from the Hornisgrinde via radio relay or ball reception . There is also an important radio link between the Merkurturm and the Stuttgart TV tower, which links the two broadcasting houses in Baden-Baden and Stuttgart .
Around two million residents in the core broadcasting area can receive the radio frequencies broadcast here, and significantly more with stationary reception via a house antenna. Thanks to the tower's exposed location, the Hornisgrinde transmitter supplies almost the entire Rhine Valley between Freiburg im Breisgau and Mannheim with radio and extends to large parts of the northern and central Black Forest, the Swabian Alb and the Neckar-Alb region. Due to reflections, the programs from the Hornisgrinde can be received in parts as far as Central Switzerland , in parts of the Palatinate and Saarland and as far as the Czech border in the Upper Palatinate.
The SWF programs of that time could be heard beyond the Vosges until the end of the 1980s . Due to international agreements with France, the transmission power to the west had to be reduced. Currently permitted radiation powers of 10 kW each on the five powerful frequencies are coordinated in this direction. Nevertheless, the programs broadcast by the Hornisgrinde are mostly to the Vosges main ridge and thus u. a. To receive in Strasbourg and the surrounding area in very good quality.
Several other companies use the transmission tower for their radio services, including the mobile network operator E-Plus and the German armed forces . Deutschlandfunk has also been broadcast from here since 2005 , the station being operated by SWR on behalf of and for the account of the responsible network carrier Media Broadcast .
The television broadcast by the station Hornisgrinde was stopped on November 5, 2008. Das Erste was broadcast here from 1954 to 2008 . Since then, terrestrial television reception in the Hornisgrinde coverage area has largely been provided by the Baden-Baden , Brandenkopf , Pforzheim and Raichberg transmitters that have been converted to DVB-T . However, since all television converters have also been switched off, terrestrial television reception is no longer possible, especially in shaded valleys.
The tower is not open to the public.

Other transmission systems
400 meters away, at the northern end of the summit plateau, is a smaller Deutsche Telekom AG transmission tower designed as a free-standing steel framework structure ( 48 ° 36 ′ 52.3 ″ N , 8 ° 12 ′ 13 ″ E ). This houses u. a. a relay station for amateur radio television . The Deutschlandfunk program was broadcast from this tower until 2005, before the station was relocated to the higher and thus more extensive SWR tower.
At the southern end of the summit plateau there is a Vodafone D2 transmission tower designed as a free-standing steel framework construction . This houses a GSM base station and serves as a radio relay node.
In the southern area of the summit level there are still several masts that were used by the military until 1994.
