Antenna Structure Ownership Map: free sample (Tensorust LLC)
160,393 registered antenna structures with owner, height and location; 112,898 are outside American Tower, Crown Castle and SBA.
Headline: Every FCC Antenna Structure Registration that is constructed or granted (160,393 structures), joined to its registered owner.

Email mattbusel@tensorust.com with the tier and a billing contact, and we will send a proper invoice (ACH or card). The file is delivered once the invoice is paid. Details and the live sample: https://tensorust.com/datasets/tower-structure-registry/. All datasets: https://tensorust.com/datasets/
Method and limits
RA records with status C (constructed) or G (granted) are deduplicated to the latest filing per registration number and joined to the owner (EN type O) and the structure coordinates (CO type T). Big three affiliation uses registered owner names (American Tower and its SpectraSite/Pinnacle/InSite entities, Crown Castle and CCATT/Global Signal, SBA entities). Portfolio size counts structures per owner FRN. Owner phone, email and contact names are dropped.
Not a list of every tower: short structures away from airports do not need an ASR. Not lease, tenant or revenue data. Owner of record can lag a sale. Not personal data: individual owners are withheld.
