The tallest guyed masts standing as of October 2026: North Dakota's KRDK-TV mast at 627.8 m leads, followed by California's KXTV/KOVR tower at 624.5 m and 17 masts tied at exactly 609.6 m (2,000 ft).
The KRDK-TV Mast near Galesburg, North Dakota, is the tallest guyed mast standing, at 627.8 m (2,060 ft). The KXTV/KOVR Tower in Walnut Grove, California, is second at 624.5 m, and 17 masts are tied for third at exactly 609.6 m (2,000 ft). The ranking uses pinnacle height of standing guyed masts from Wikipedia's List of tallest structures, as of October 2026.
Guyed masts are slender lattice structures held upright by steel guy wires anchored to the ground. Used mainly for television and radio broadcasting, they include the tallest structures in the Western Hemisphere. Every guyed mast standing above 600 m is in the United States. This list ranks guyed masts standing as of 18 October 2026 by pinnacle height. Because 17 masts are listed at exactly 609.6 m (2,000 ft), all of them are tied for third place and the list runs to 19 entries rather than 10. The KVLY-TV mast, long described as the world's tallest, is no longer in the top group: an antenna change in 2019 reduced it to about 605 m.
The KRDK-TV mast near Galesburg, North Dakota, is listed at 627.8 m (2,060 ft), making it the tallest guyed mast standing and the tallest structure in the United States. The current mast was built in 1998 after the previous masts on the site collapsed in 1968 and 1997.

Source: Wikipedia, List of tallest structures (revision 1380379231, retrieved 18 October 2026), which gives pinnacle heights (largely from FCC antenna structure registrations) and marks which structures are guyed masts and which are no longer standing. We include every guyed mast in that table that is still standing and taller than 609 m. Structures marked as collapsed or demolished are excluded, including the Warsaw Radio Mast (646.4 m, collapsed 1991), the KATV tower (609.6 m, collapsed 2008), the WECT tower (609.6 m, demolished 2012) and the KTVO-TV tower (609.6 m, collapsed 1988). Ranks 3 to 19 are a 17-way tie at 609.6 m; within the tie, masts are ordered by the year the source gives, then alphabetically, and that order carries no meaning. Self-supporting towers and buildings are excluded.
The KRDK-TV mast near Galesburg, North Dakota, listed at 627.8 m (2,060 ft). It is also the tallest structure in the United States. Second is the KXTV/KOVR tower at Walnut Grove, California (624.5 m).
No. The KVLY-TV mast at Blanchard, North Dakota, was 628.8 m (2,063 ft) when completed in 1963, but an antenna change in 2019 reduced it to about 605 m, below the KRDK-TV mast and the many masts listed at 609.6 m.
609.6 m is 2,000 ft. US regulators apply a presumption against antenna structures over 2,000 feet above ground level, so many broadcast masts were built to exactly that height. Seventeen standing masts are listed at 609.6 m.
The Warsaw Radio Mast in Konstantynów, Poland, at 646.4 m. Completed in 1974, it collapsed on August 8, 1991, during guy wire replacement.
