The RKS Liblice 2 are two 355 m (1,165 ft) tall guyed masts located east of Prague near Liblice, in close proximity of the RKS Liblice 1. These lattice steel towers are built 120 m (390 ft) apart from each other, at which cage aerials are mounted. Designed by Jan Šťovíček, these supertall towers currently stand as the tallest towers in the world used for broadcasting in the medium-wave range. RKS Liblice-2 was built in 1976, and is currently used for broadcasting on 639 kHz. During construction, two new transmitter devices of the type Tesla SRV 750 with an output power of 750 KW were installed. In regular operation, these transmitters are switched in parallel for a transmission power of 1500 KW.
History[]
The RKS Liblice 1 was once two 280.4 m (919.9 ft) tall towers before it was demolished on October 17th, 1972 in lieu of the construction of the current towers. The original towers were built in 1936, by Karlova Huť; these towers survived World War II without damages.
Incidents[]
- On November 23, 1978, the transmission frequency of the new towers, which was 638 kHz since 1950, was changed to 639 kHz in order to fulfill the regulations of "waveplan" of Geneva.
- On August 27, 2005, a skydiver jumped off one of the masts after gaining illegal access to it. His parachute became accidentally hooked to a backstage insulator. Fortunately, the incident did not get him too close to the cage antenna of the tower, which would likely have led to his death due to the presence of high frequency currents.
