Who owns the towers in Union County
20 different registrants own the 29 structures. One is registered to an individual or family trust, whose name this site withholds. Owner names are the registrant's legal entity as filed with the FCC; the large tower companies file under many subsidiary names, which this site groups into families where the brand is in the name or listed in the company's SEC filings.
Height and age
The median structure here stands 308 feet, 48 feet taller than the South Carolina median — a sign of broadcast and rural coverage towers rather than short suburban sites. The tallest is a tower near Union at 499 feet, built in 2003. More than in any other decade, 48% 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.
