About this data
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.
