The Media Bureau provides information from its Broadcast and Cable databases for public download and use.
Users should be aware that the database information is primarily intended for staff use and may not include all the data desired. All databases and related information are provided as-is and any use is at the user's sole risk. Additionally, we do not have the staff resources to permit us to provide individual assistance with setup and reading of the databases. While we strive for accuracy, users are cautioned that the databases may not be entirely free from errors. Please bring errors to our attention so that we can correct them promptly.
For your convenience, the individual CDBS text files listed are included in the large (on the order of 120 MB) all-cdbs-files.zip zipped file. These files are automatically updated at approximately 4:00 AM Eastern time on the morning after each business day.
Users are advised that these service contours may not provide sufficient detail for digital television allocations work, but they do provide a useful, simple representation of expected digital television coverage.
