Blosenbergturm

With a total height of 217 metres (712 ft) it is currently the sixth tallest structure in Switzerland.

It has a cabin at a height of 150 m (490 ft), containing a coil for feeding the pinnacle, which is insulated against the rest of the tower, separately with high frequency power.

The aircraft warning lights on the Blosenbergturm have a special feature: at dawn, a rotating beamer above the cabin comes into service.

The high electrical field surrounding the top of the tower when the transmitter was powered meant that at such times the light glowed faintly, even in the blink breaks.

The Beromünster transmitter was shut down at midnight (CET) on 28 December 2008, despite some protests against the measure.
