Who owns the towers in Carroll County

Height and age
The median structure here stands 258 feet, 51 feet taller than the Illinois median — a sign of broadcast and rural coverage towers rather than short suburban sites. The tallest is a tower near Shannon at 510 feet, built in 1995. More than in any other decade, 31% were built in the 1990s.
Every registered structure
Sorted tallest first. The registration number opens the FCC record, which shows the exact location and the owner's contact for the structure. A tower on your land that is not in this list is probably under 200 feet and away from airports, so it did not need registering — see why some towers aren't listed.
