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 2,063 feet (629 meters) until 2019, when the top mount VHF antenna was removed for the FCC spectrum repack, dropping the height to 1,987 feet (605.6 m).

In 1974, it 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. It became the third tallest when the Tokyo Skytree was completed in 2012, then the fourth tallest when the Shanghai Tower took third place in 2013. It remained the tallest structure in the Western Hemisphere, and the tallest broadcasting mast in the world until the antenna removal in 2019.
