The Lauterach transmitter is a facility for the distribution of VHF radio programs (until January 1, 1995 also a radio program on the medium wave frequency 1026 kHz, before the introduction of DVB-T also of television programs, until December 31, 2010 also of DVB-H) of the ORF near Lauterach in Vorarlberg . A 116-meter-high, guyed steel framework mast is used as the transmission mast, which is insulated from the ground and which is similar in its construction to the two masts of the former Aldrans transmitter . Possibly it is the oldest broadcasting mast of the ORF. The Lauterach transmitter went into operation in 1933 and at the end of the Second World War it was one of the last functional radio transmitters in what was then the German Reich. The system also includes a second, smaller antenna, isolated from earth, which served as a parasitic element to change the radiation pattern . This was because a transmitter in Norway was using the same frequency. The second antenna was used as a "director". The entire transmission system is now a listed building .

Although the Lauterach transmitter is no longer used as a medium wave transmitter today, it should still be possible to use this system for this frequency range and was temporarily planned for truck radio .

history

The Lauterach transmitter went into operation on November 15, 1933 on an experimental basis with an output of 200 watts . The official commissioning took place on December 18, 1934 with an output of 2 kilowatts on the frequency of 1294 kHz, which was allocated to Austria under the Lucerne Wave Plan . In the spring of 1935 the transmitter was modernized and the transmission power increased to 5 kilowatts. In the Third Reich , the station came to the Reichsender Stuttgart. On May 2, 1945, the Dornbirn region was occupied by French troops. Transmission continued without interruption. Soon a single wave was formed with the Aldrans transmitter on 519 kHz, until it was switched to the frequency of 629 kHz on March 15, 1950 as part of the Copenhagen Wave Plan . A year later, the output could be increased to 12 kilowatts. At the beginning of December 1954, the station came to the Austrian Broadcasting Corporation (ORF), which still operates it today as an FM filling station. This put new transmitters into operation on December 6, 1955, with which the first program was broadcast on 629 kHz with 25 kilowatts and the second program on 1025 kHz with 10 kilowatts. Since October 1, 1967 - the date of the introduction of the ORF regional programs - the cultural program Austria 1 (Ö1) was broadcast on 1025 kHz and the regional program Austria Regional (Ö2) on 629 kHz. On September 5, 1977, the broadcast of the first program was set to 629 kHz and the 25 kilowatt transmitter was retuned to 1026 kHz. In addition, a further 25 kilowatt transmitter was moved from another disused transmitter location to Lauterach and a mixed program from the programs Ö1 and Austria Regional ( Ö2 ) was broadcast with the interconnected transmission power of 50 kilowatts . This transmission power was used until 1987, when it was finally reduced to 25 kilowatts. On January 1, 1995, the medium-wave transmitter was completely shut down. Thereafter, the Dornbirn transmitter served as a transmitter for VHF and TV until analog television was switched off on April 14, 2008. From autumn 2008 to December 31, 2010, the Dornbirn broadcaster also broadcast DVB-H . Since then this location has been broadcasting on VHF.
