Description • Blosenbergturm is a free-standing tower radiator
insulated against ground. It has in a height of 150 metres a cabin, in which there is a coil for electrical lengthing.
Over this coil the pinnacle is fed with radio power to be radiated.
• Until 1964 the tower was used as dipole for mediumwave whereby one dipol half was the section above the cabin and the other that below the cabin.
• Blosenbergturm is a part of Beromünster mediumwave transmitter ( German: Landessender Beromünster ).
• It broadcasted until December 28th, 2008 the program of DRS on 531 kHz with 180 kW ( before 2003 600 kW ). On December 28th, 2008 at 24:00 MST it stopped broadcasting
the program. On the last days of 2008, it transmitted an endless message, before on December 31st, 2008, it was shut-down. On its frequemcy one can receive in Europe know
at night the signal of AinBeida transmitter
( http://skyscraperpage.com/cities/?buildingID=76669 ).
• Future of facility is uncertain. Some want to transform the tower into an observation tower, while there are also companies, which want to use it for broadcasting their program on 531 kHz as this frequency has a good groundwave propagation.
• The air traffic obstacle lights of Blosenbergturm have a special feature: at dawn a rotating beamer above the cabin is in service. This beamer, which is much less bright, than the beamers on Stuttgart TV Tower is switched off at night and the red air-traffic obstacles warning lights are turned on. By watching the blinking lamp on the pinnacle of the tower one can see, if transmitter is working. It glows faint in the blink breaks while transmitter works as result of the high electric field at the top, when transmitter is working.
• There is a second 126 metre tall freestanding lattice tower nearby, which is as Blosenbergturm a tower radiator insulated against ground. This tower, which was built in 1931, carried until 1962 together with a second tower, which was dismantled and rebuilt in St. Chrischona near Basel as TV transmission tower, a T-antenna for medium wave. After dismantling the second tower it was transformed in a tower radiator, which serves now as backup transmission for the Blosenbergturm.
