About this data

All figures on this page are aggregated from the federal antenna structure register of 2026-08-23, not from carrier coverage data. The two answer different questions.

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.
