About this record
A slender mast held upright by tensioned cables anchored around it. The cheapest way to go very tall, which is why most structures above 300 m are guyed.
Record 120646 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.
