About this data
Counts here are computed from the FCC's registered structure file, dated 2026-08-23. If a mast near you is missing, the usual reason is that it sits below the 200-foot registration threshold.
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.
