List of tallest structures in the United States

The height of structures in the United States has been poorly documented. However, the data is a matter of public record, appearing in documents maintained by the Federal Aviation Administration (FAA) and Federal Communications Commission (FCC).

This list is populated heavily by antenna masts. The engineering aspects of super-tall masts are highly specialized. Only four companies erect the majority of such structures: Doty Moore Tower Services (Cedar Hill, Texas); Kline Towers (Columbia, South Carolina); LeBlanc Royal Telecom (Oakville, Ontario); and Stainless Inc. (North Wales, Pennsylvania). The design and construction are largely governed by RS222E Electronic Industries Alliance standards. A 1,000-foot (300 m) mast costs between $0.7 and $1.1 million to build, while a 2,000-foot (610 m) mast costs $2.4 to $4 million. Prices generally vary depending on tower capacity and wind loading specifications.

A common misperception is that landmarks such as the Stratosphere Tower are the tallest United States structures, but they are in fact the tallest buildings. Likewise Taipei 101 was often misrepresented as the world's tallest structure (although it was the tallest occupied building, before the certification of Dubai's Burj Khalifa as such), but in fact is far eclipsed by antenna towers in over a dozen states in the United States and in other countries.

In the United States, the FAA and the FCC must approve all towers exceeding 200 feet (61 m) in height. Furthermore, it is very difficult to get permission for structures over 2,000 feet (610 m) high. The FCC presumes them to be inconsistent with the public interest, while the FAA presumes them to be a hazard to air navigation, resulting in poor airspace usage. A significant burden of proof is placed on the applicant to show that such a structure is in the public's best interests. Only when both agencies have resolved all legal, safety, and management concerns is such an application approved.

Since 1978 the United States has maintained eleven tethered aerostats sites along the southern borders. These balloons rise to 18,000 feet (5,500 m), carrying radar units for drug interdiction purposes. However, since the balloons are aided by buoyancy and are not permanent they are not considered true structures.

  • Year built: 2003

  • The primary reason for the tower is to get radio stations who do not have a license for the Denver area to get into the Denver area (big advertising bucks). According to Raymond Morris, "I was the previous owner of the land on which the tower was located. I was trying to negotiate a lease with them, but the going got tough and I ended up selling 367.3 acres [1.5 km²] from a larger piece of land, (4,000 feet × 4,000 feet) [1.2 by 1.2 km]."

  • This tower was known as the KTHI Television Tower until June 1995. It is the third-tallest structure in the world, eclipsed only by the Burj Khalifa in Dubai, United Arab Emirates (completed in 2009), and the Tokyo Sky Tree in Tokyo, Japan (completed in 2012). From 1974 until its collapse in 1991, the Warsaw radio mast in Poland also eclipsed the KVLY-TV mast. This tower is used so KVLY-TV can cover both Fargo and Grand Forks.

  • The KRDK-TV tower is the world's fourth-tallest man-made structure. It had collapsed three times due to winter and summer storms, though the first time it collapsed in 1968, it was caused from a Marine helicopter cutting four guy wires of the tower. The KVLY TV tower, the world's third-tallest man-made structure, is only about six miles (10 km) from the KRDK-TV tower. This tower is used so KRDK-TV can cover both Fargo and Grand Forks.

WCOM-TV signed on March 3, 1988. Height of the tower was 1,576 ft (480 m). WCOM-TV used the tall tower and a directional antenna to try to serve the Columbus market.

An engineer has reported that part of the tower was still on the ground in Sumter, South Carolina.

When used for television broadcasts by its former owner, Multimedia, Incorporated (former licensee of WBIR-TV, Knoxville) it was shielded by mountains from the audience in the western Knoxville suburbs like Farragut, Oak Ridge, and Oliver Springs. This tower was built because the owners of WBIR-TV could not obtain land atop nearby House Mountain, because the only land suitable for a television tower base on the mountain had been purchased by the station's main competitor WATE-TV, Knoxville. When completed, it was for a short time the tallest man-made structure on earth.
