Lakihegy Tower
The transmitter Lakihegy is a transmission tower south of the Hungarian capital Budapest on the Danube island Csepel.
History
The station was built in 1933 as a self- radiating transmission tower with a height of 314 meters. At the time of its construction it was the tallest building in Europe, in Hungary is a listed building and is today one of the tallest buildings in Hungary.
The transmission tower was blown up on 26 November 1944 by the South East Europe receding, the German armed forces in the context of the scorched earth strategy. The plant was rebuilt in 1948; In 2006 she was overhauled.
Technology
The transmission tower, like all radiating transmitting towers, when operating under high voltage. As of 2012, the tower is used as a medium wave transmitter from the Hungarian broadcasting at the transmission frequency 546 kHz with 150 kW and diplexed to broadcast the European radio ripple control signal ( ERA) to 135.6 kHz with 100 kW.
It has a fish belly cross-section which is called Blaw -Knox transmission tower. This widespread in North America mast design is used in Europe only at the transmission towers in the Northern Ireland Lisnagarvey, the Bulgarian Wakarel and Stara Zagora (both in Bulgaria). There also exist in Lakihegy two more small guyed masts for medium wave conventional design.
Another transmitting antenna consisting of two freestanding towers at 47 ° 22 ' 25 "N, 18 ° 59 ' 0" O47.37372222222218.983261111111 is powered by a 2.1 -kilometer Reuse wire from the transmitting building.
In 2006 took part in the transmitter of the long -wave mode for the ripple control signal of the European radio ripple control ( ERA) started broadcasting on. This signal is used for automatic and cross-border remote control of consumers in the supply network of several Central European energy supply companies. Is used for the long wave frequency of 135.6 kHz with an output power of 100 kW. The digitally encoded control data is transmitted with a symbol rate of 200 baud for the communication standard IEC 60870-5.
