It is taller than 98.6% of the 5,157 registered structures in Illinois, placing it 73rd statewide.
American Towers LLC holds the registration. Tower companies like this one lease space on their structures to multiple carriers, so the registered owner does not tell you which networks operate here.

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.
Source data is the FCC ASR record for structure 120721, which gives a construction date of 1985. Registrations are updated when a structure changes, so figures reflect the most recent filing rather than continuous monitoring.
"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.
