Long wave transmitter Orlunda
In the vicinity of Orlunda near Motala in Sweden , the Swedish radio operated the long-wave transmitter Orlunda from 1962 to 1991 , which used an arrangement consisting of a 250 meter high central mast and five 200 meter high transmitter masts set up in a circle, all of which were isolated from the ground and were fed at the foot point, the feed of the central mast and the radial masts being in phase opposition. With this arrangement, a very effective fading-reducing transmission antenna for long waves was achieved . In July 1970, the base point insulator of the central mast was destroyed by a lightning strike , whereupon it collapsed. In 1991 the transmission was stopped and in 1994/1995 the last two transmission masts were dismantled.
At the location of the former central mast there is now an 86.4 meter high guyed transmitter mast for cellular communications.
