Overview

The tower is located three miles west of Blanchard, North Dakota, 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, which collapsed on August 8, 1991, making the KVLY-TV mast again the tallest structure on land. The still-under-construction Burj Dubai in Dubai, United Arab Emirates, planned for completion in 2009, has surpassed the mast as the tallest land structure. As of September 2, 2008, the website for the Burj Dubai project reported that it has reached a height of convert|2257|ft|m|0. However, the Council on Tall Buildings and Urban Habitat will not recognize the Burj Dubai figures as official until that building is complete.

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.

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) which is a radius of about 97 miles.

Its height above mean sea level is 3,038 ft (926 m). Some time after its completion, the Federal Government imposed a law that states "Although there is no absolute height limit for antenna towers, both agencies have established a rebuttable presumption against structures over 2,000 feet above ground level." [http://www.fcc.gov/mb/policy/dtv/lighting.html] The FCC and FAA may approve a taller structure in "exceptional cases."

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 elevator or ladder.
