Cell towers in Lockport, Illinois
The FCC register lists 23 antenna structures in and around Lockport. That is the 17th highest count of any place in Illinois.
Overview
Lockport, IL has 23 registered structures, the tallest standing 140 m (460 ft) above ground.
Counted against 27,822 residents, that is 82.7 per 100,000 — worth reading alongside area density, since structures cluster along roads and ridgelines rather than where people sleep.

The largest registered owner here is American Towers LLC, which holds 3 of them — 13.0% of the local total. Owner is not the same as carrier: tower companies lease space on their structures to several networks at once.
Registrations here span 1983 to 2015.

About this data
These counts come from the FCC Antenna Structure Registration database, weekly file dated 2026-08-23. Registration is generally required above 200 feet or near an airport, so small cells, rooftop antennas and short masts do not appear.
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.
