Terms of Use

Last updated 2026-10-04

Not legal advice. This site publishes structured extracts of public federal filings. It is not a law firm, does not provide legal advice, and nothing on it is a substitute for reading the FCC's own record or consulting a qualified professional.
Not affiliated with the FCC. This is an independent reader of FCC public files. It is not affiliated with, endorsed by, operated by, or sponsored by the Federal Communications Commission or any government agency. The FCC's Antenna Structure Registration database is the authoritative record — verify anything that matters against it.

What this service is

This site reads the FCC's daily public transaction files for antenna structure registrations and organises them by owner, so a tower owner or contractor can see what changed without querying the database by hand. Every entry links to the FCC's own record for that filing.

Accuracy, and what is not verified

We reproduce what the FCC's public files say. We do not verify it. In particular:

  • Owner names are as filed, and are NOT verified. A name in an FCC filing is a string someone entered, not a confirmed legal identity. Names that look similar are not merged, and a single company's filings may appear under several spellings and filing codes.
  • Filing dates are the dates the FCC's file records, which may differ from when a construction activity actually happened.
  • Coverage is a rolling window. The FCC publishes a daily file and removes older ones, so this archive reflects the window we have been able to ingest, not all history.

The service is provided "as is", without warranty of any kind, express or implied, including fitness for a particular purpose. We are not liable for any loss arising from reliance on it.

Acceptable use

Read it, cite it, link to it, and use the public JSON API and RSS feed. Do not attempt to overload the service, misrepresent its output as an official government record, or use it to harass any person or company named in the filings.

Changes

These terms may change. The date at the top of this page always reflects the current version. Continuing to use the site after a change means you accept it.

Questions, corrections or removal requests: use the contact page or email [email protected].
