history
Located five kilometers west of Blanchard , the KVLY TV mast became the tallest structure on earth when it was completed on August 13, 1963. From 1974 it was towered 18 meters above the Konstantynów long-wave transmitter mast in Konstantynów , which collapsed on August 8, 1991, making the KVLY mast again the tallest structure on earth and this remained until January 31, 2008, when the construction site was completed of the Burj Khalifa overtook him.
The mast was constructed of steel by Hamilton Directors and Kline . It took 33 days to build and cost half a million US dollars (4.2 million dollars based on today's purchasing power). The height of the spire is 629 meters.
Owner of the mast is the Meyer Broadcasting Company of Bismarck , with a capacity of 316 k W on channel 11 (199.25 M what Hz corresponds and a wavelength of about 1.5 m) is an analog television program in the television standard NTSC for the television station KVLY, an affiliate station of NBC , which is based in Fargo . The supply area of the KVLY mast is around 77,700 km² and is therefore slightly larger than the area of Serbia .
The call sign of the television station for which this mast was built was originally KTHI, with the "HI" referring to the height of the mast. The top of the mast with the transmitting dipoles can be reached via a maintenance elevator and a ladder.
The future and the eventual collapse of the mast system after a fictional disappearance of mankind is shown in episode 8 of the 2nd season of the documentary fiction series Future Without People (“Chaos am Himmel”, USA 2010).
The second highest mast on earth is the only one meter smaller KXJB TV mast , only a few kilometers away.
