Who owns the towers in Grundy County
29 different registrants own the 38 structures. 2 are registered to individuals or family trusts, whose names this site withholds.

Height and age
The median structure here stands 240 feet, 33 feet taller than the Illinois median — a sign of broadcast and rural coverage towers rather than short suburban sites. The tallest is a structure near Morris at 500 feet, built in 2000. More than in any other decade, 42% were built in the 2000s.
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.
