KVLY-TV mast

The KVLY-TV mast (formerly the KTHI-TV mast) is a television-transmitting mast in Blanchard, North Dakota. It is used by Fargo station KVLY-TV (channel 11) and KXJB-LD's Argusville/Valley City/Mayville translator K28MA-D (channel 28), along with KNGF (channel 27). Completed in 1963, it was once the tallest structure in the world, and stood at 628.8 metres (2, 063 ft) until 2019, when the top mount VHF antenna was removed for the FCC spectrum repack, dropping the height to 605.6 metres (1, 987 ft). In 1974, the KVLY-TV mast was succeeded by the Warsaw radio mast as the world's tallest structure. The Warsaw mast collapsed in 1991, again making the KVLY-TV mast the tallest structure in the world until the Burj Khalifa surpassed it in 2008. The KVLY-TV mast remained the tallest structure in the Western Hemisphere and the tallest broadcasting mast in the world until the removal of its antenna in 2019.
