Longwave transmitter Orlunda

The Longwave transmitter Orlunda was a broadcast transmission facility for longwave at Orlunda , Sweden near Motala, which was established in 1962. It used as aerial an arrangment of 6 guyed steel framework masts, which were insulated against ground. 5 masts were 200 metres tall and arranged on a circle around a 250 metre tall central mast. The masts on the circle were fed with opposite phase then the central mast, which gave a very flat radiation pattern (fading reducing aerial). In 1970 the central mast collapsed after a lightning strike destroyed its basement insulator. In 1991 the transmitter was shut down and in 1995 the last radio masts of the facility were demounted.
