Frequently asked questions
What is the most common tower type in the US?
Tower (type not specified) (code TOWER) is the most common registered structure type with 75,302 of 197,703 registrations.
What type are the tallest towers?
The single tallest registration, 628 m, is filed with structure-type code TOWER. The tallest filed as a guyed tower (GTOWER) reaches 625 m. Nearly every structure above 500 m is a broadcast mast held up by guy wires, but many were registered under the FCC's older general "TOWER" code, which does not record the support method.
