Located at the peak of the Säntis is a 123.55 meter high transmission tower, which was commissioned in November 1997. The original tower stemming from the year 1955 had to be renovated several times due to the rough weather conditions before finally being replaced. The antenna of the new transmission tower got a fibre-glass enforced plastic layer on the outside in order to prevent ice falling onto the visitors' terrace. Swiss radio channels such as DRS 1, DRS 2, DRS 3, RSR la Première and RSI Rete Uno are broadcast from the tower. Swiss television channels such as SF 1, SF 2, SF Info, TSR 1 and TSI 1 are also broadcast from this location.
