About this record
One element of a 3-tower array. Multi-tower arrays are typically AM broadcast antennas, where the towers work together to shape the signal in a particular direction.
Record 617821 is drawn from the FCC ASR weekly file dated 2026-08-23. The database covers structures that require registration — generally those over 200 ft or near airports — so shorter masts and small cells will not appear.
"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.
