Alpstein

The Säntis transmitter is a 123.5 m (405.3 ft) high transmitting station on the summit of the 2,502 m (8,209 ft) high Säntis mountain in Switzerland. It is operated by Swisscom.The original microwave station (a barrack with wooden antenna trestles) was built in 1955, but because Säntis is directly exposed to north-western weather the unprotected microwave radio antennae regularly iced up in winter. It was therefore decided to rebuild the station and to shield the antennae with polyurethane panels. This gives the station its unique "look", the bubbles one can see on the left part of the photograph. With over 100 strikes per year, the tower is considered to be amongst the constructs most frequently hit by lightnings.

At 2,501.9 metres (8,208 ft) above sea level, Säntis is the highest mountain in the Alpstein massif of northeastern Switzerland. It is also the culminating point of the whole Appenzell Alps, between Lake Walen and Lake Constance. Shared by three cantons, the mountain is a highly visible landmark thanks to its exposed northerly position within the Alpstein massif. As a consequence, houses called Säntisblick (English: Säntis view) can be found in regions as far away as the Black Forest in Germany. Säntis is among the most prominent summits in the Alps and the most prominent summit in Europe with an observation deck on the top. The panorama from the summit is spectacular. Six countries can be seen if the weather allows: Switzerland, Germany, Austria, Liechtenstein, France, and Italy.
