The state transmitter Sarnen in Sarnen in the canton of Obwalden was a facility of the Swiss radio to broadcast the first program of the Swiss radio in the medium wave range. In contrast to the state transmitter Beromünster , which worked on the transmission frequency 531 kHz at the lowest end of the medium wave range, the state transmitter Sarnen was operated on the transmission frequency 1566 kHz, which is at the upper end of the medium wave band. With such frequencies, a low surface wave range is achieved, but a large sky wave range during the night. For this reason, the national broadcaster Sarnen was only in operation at night. It used a steep-beam antenna as a transmitting antenna and was in operation from 1973 to 1992.
The antenna consisted of two horizontal dipoles each 170 meters long and 96 meters apart. Each dipole was attached to three 40 meter high freestanding steel lattice towers, which seemed a bit strange because of the lack of diagonal struts. The towers in the center of the dipole had a square cross section, those at the ends of the dipoles had a triangular cross section.
The Sarnen state transmitter was shut down at the beginning of the 1990s and gradually dismantled from the beginning of 2013.
