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) tall mast costs between $0.7 and $1.1 million to build, while a 2,000-foot (610 m) tall 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) tall. 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 11 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.

The KVLY-TV mast is a television-transmitting mast in Blanchard, North Dakota. It is used by Fargo station KVLY-TV and KXJB-LD's Argusville/Valley City/Mayville translator K28MA-D, along with KNGF. Completed in 1963, it was once the tallest structure in the world, and stood at 2,063 feet 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).
The KRDK-TV mast is a television transmitting tower in Traill County, North Dakota, United States. At 2,060 ft (630 m), it is currently the tallest structure in the United States, the second-tallest structure in the Western Hemisphere and the seventh-tallest structure in the world. It stands 72.8 ft (22.2 m) taller than the nearby KVLY-TV mast in Blanchard, North Dakota, which was previously 3.3 ft (1.0 m) taller until the removal of a VHF antenna reduced its height in 2019.
The KATV tower was a 2,000-foot (610 m)-tall television mast built in 1965, which was located in Barraque Township, Arkansas, off of Arkansas Highway 365. At the time of its completion, it was the third-tallest human-made structure and second-tallest broadcast tower in the world, and the tallest structure in Arkansas. As of August 2006, the tower was tied with 15 other 2000-foot masts, all built after it, as the fifth-tallest structure in the world.

Radio masts and towers are typically tall structures designed to support antennas for telecommunications and broadcasting, including television. There are two main types: guyed and self-supporting structures. They are among the tallest human-made structures. Masts are often named after the broadcasting organizations that originally built them or currently use them.
New Zealand Masts and Towers range in size from short flagpoles to high radio transmitter antenna structures. The highest mast is in Titahi Bay, being the highest structure in the Southern Hemisphere at time of construction. Later it became the highest in New Zealand and then later second to the Sky Tower in Auckland.
