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.
These figures come from the FCC's Antenna Structure Registration database, filed under registration 109743. Heights and coordinates are as submitted by the registrant, not independently surveyed.
"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.
