KVLY-TV mast
The KVLY-TV mast (formerly the KTHI-TV mast) is a television transmitting
mast in Traill County,
North Dakota,
Overview
The tower is located three miles west of Blanchard, North Dakota, which is roughly halfway between Fargo and Grand Forks. It became the tallest artificial structure upon the completion of its construction on August 13, 1963. The mast was surpassed in height by 18 m (57 ft) in 1974 by the Warszawa radio mast near Konstantynów, Poland, but the latter collapsed on August 8, 1991, making the KVLY mast again the tallest structure on land. If completed as planned, the UAE's Burj Dubai, presently slated for completion in 2008, will surpass the mast as the tallest land structure.
The tower was built by Hamilton Directors and Kline Iron and Steel, and took thirty days to complete, at a cost of US$500,000 ($3.3 million in 2007 dollars).
Owned by Hoak Media of Dallas, Texas, the tower broadcasts at 316 kW for television station KVLY (channel 11, an NBC affiliate) which is based in Fargo. The tower provides a broadcast area of roughly 30,000 square miles (78,000 km²).
Its overall height above mean sea level is 926 m (3,038 ft). Some time after its completion, the Federal Aviation Administration imposed a limit of 2,063 ft, based on this tower's height, on future construction; consequently, no taller structures may legally be built in the U.S. at present.
The call letters of the television station for which it was built were originally KTHI, the "HI" referring to the height of the mast. The top is reachable by service elevator or ladder.
