The antenna carrier used is a freestanding tubular steel mast. Although it is only 55 m high, thanks to its location it can supply almost the entire Bavarian Alpine foothills and parts of Austria with TV and FM programs. In May 2005, the analogue broadcasting of ARD, ZDF and Bavarian Television was discontinued and replaced by digital broadcasting in the DVB-T standard. All Munich multiplexes are also transmitted by the Wendelstein and are thus well received in large parts of Upper Bavaria.
From Wendelstein today also all South Bavarian transmitters of the Bayerischer Rundfunk are remotely monitored, if they are due to the time of day or permanently unoccupied. The transmitter operating center for the northern Bavarian region is located on the Dillberg.
The transmitter Wendelstein was taken on 3 January 1950 on the FM frequency 88.5 MHz for Bayern 2 in operation. Due to the European Broadcasting Agreement Stockholm in 1952, this frequency had to be shifted to 90.0 MHz on 1 July 1953, after it had reached 88.9 MHz in the meantime. In 1954, the transmission power was increased from initially 1 kW to 100 kW and at the same time the 93.6 MHz frequency for Bayern 1 was put into operation. In 1961, the FM frequencies were re-coordinated, with the frequency changed from 90.0 MHz to 89.5 MHz and the frequency 93.6 MHz to 93.7 MHz.
Television signals came for the first time in early November 1954 from Wendelstein, for which a 100 kW strong television channel for VHF channel 10 was installed.
Already 10 years later the Bavarian broadcasting company built a new 55 meter high mast and on 1 November 1964 commissioned the frequency 98.5 MHz with a power of 35 kilowatts for its former guest worker program Bayern 3.
Bayern 4 Klassik was first broadcast on 4 October 1984 by Wendelstein, first on the frequency 103.3 MHz with 5 kilowatts, from the end of 1986 then to 102.3 MHz with the full 100 kilowatts of transmission power. In 1989, the RDS was put into operation. The next commissioning of a VHF frequency did not last long, it was already broadcast from 1988 on the frequency 105.7 MHz, the guest worker program with 2 kilowatts of broadcast power, after its recruitment in May 1991 then B5 current. At the end of 1992, this frequency was also increased to the full 100 kilowatts.
Digital radio (DAB) was first put on 8 June 1995 as a pilot project, from 1999 then in regular operation. After initially only the DAB ensemble was broadcast on 12D, came on 16 December 2010, the BR-Mux on 11D with 4 kilowatts of power.
In April 2005, as part of the conversion to DVB-T, the mast received a new tip made of glass fiber reinforced plastic with the new UHF antennas.
