About this data
Figures are drawn from the FCC's public antenna structure register (2026-08-23). It covers structures that need registering — broadly those over 200 feet or close to an airport — and not the many shorter installations that carry mobile traffic.
The FCC Antenna Structure Registration database covers structures that require registration — generally those over 200 feet or near airports. Many small cells, rooftop antennas and short towers are not registered and will not appear here.
"Owner" is the entity that registered the structure, usually a tower company such as American Tower or Crown Castle. It does not indicate which carriers operate equipment on the structure.
