The Säntis transmitter is a 123 meter high reinforced concrete transmission tower on the Säntis . The tower is used by the Swisscom Broadcast company to distribute radio and television programs throughout Northeastern Switzerland and is normally not open to the public - guided tours are possible by appointment. In addition, the tower takes over directional radio links for television program feed, professional radio and services for GSM and serves as a measuring station for the Federal Office for Meteorology and Climatology .
location
The Säntis transmission tower stands on the mountain of the same name at an altitude of 2501 m above sea level. M. in the area of the communities Hundwil , Schwende and Wildhaus . The tower itself is located in the Wildhauser area. The mountain station of the Schwägalp – Säntis cable car is adjacent .
history
In 1955, the Federal Council asked the National Council and the Council of States to approve a loan of 890,000 Swiss francs for the construction of a telecommunications building . The predecessor of today's transmission tower on the Säntis was built in 1956 by the PTT , was 18 meters high and was officially inaugurated in 1958. In 1957 the first VHF radio station ( DRS 2 ) went into operation. After a competition, the project order for extensions was awarded in 1968 and after two years of preparatory work, construction began in 1971, as the old transmission tower from 1955 had to be renovated several times due to the extreme weather conditions. In 1975 the new broadcasting center was put into operation. At that time it was the largest structure of its kind in Europe. The television programs of French - and Italian - speaking Switzerland were re-broadcast in 1976.
The first submission for a building project, "Säntis 2000" , was submitted in 1992, aimed at expanding the south cavern , building a new antenna tower and renovating the weather station building . In 1995 work on the project could begin. In 1997 the old tower was demolished and the new, 123 meter high antenna tower was put into operation. The opening ceremony took place on June 17, 1998.
As part of the restructuring of the Swisscom Group in 2002, the subsidiary Swisscom Broadcast AG became the owner of the transmission system. After the broadcast of digital television ( DVB-T in Switzerland ) was started in 2007, the analog television program was switched off. On June 3, 2019, the broadcasting of digital television programs ended.
Building
The antenna of the new transmission tower is encased in fiberglass-reinforced plastic and can be heated to prevent ice falling onto the visitor terrace below. The diameter of the mast base, which weighs 4164 tons, is 5.49 meters and the diameter of the top of the tower is 1.82 meters.
use
A large part of central and eastern Switzerland is covered by this transmitter . The station can also be received in large parts of southern Germany and neighboring countries. There is also a radio link to the Pfänder transmitter in Austria. The Säntisturm broadcasts five radio programs.
