Antenna Structure Registration

I understand that for certain antenna structures I must provide an FCC Antenna Registration Number when I file a license application. However, I do not know whether an FAA study has been completed for the structure where I intend to locate the antenna. Is there a database that contains this information?

FAA records are posted under "Downloads" on the ASR homepage. Or you can contact the Licensing Support hotline (888-225-5322, option 2) and a representative can verify this information for you.

NOTE: To resolve this situation, you have a number of options. For example, you can get the owner to register the structure properly by helping her with the administrative details. You can also notify the FCC's Enforcement Division formally or informally in regard to the owner's failure to comply with the requirements of 47 CFR Part 17.

TOWAIR determines whether structures less than 60.96 meters (200 feet) above ground require registration. What information do I need when I run TOWAIR? Does height information have to be in meters or feet?

To use TOWAIR, you must supply the coordinates of the site, the site elevation, and the overall height of the structure. The software allows you to enter data in feet or in meters.

The FCC maintains database files (in "zip" format) on its Internet web site for its licensing databases, as well as the Antenna Structure Registration (ASR) database. How frequently are the zip files updated? How often does the FCC update the list of airports, which is required to run TOWAIR?

License and registration zip files are updated weekly. The FAA updates the airport data, which is used by TOWAIR, approximately every fifty-six (56) days.

Where do I obtain the most accurate tower registration information if we cannot obtain this information from the owner?

According to 47 CFR § 17.4(f), owners are required to provide a copy of the antenna registration (FCC Form 854-R) to you and every other tenant licensee immediately upon registration. Information regarding antenna structures registered with the FCC is available in "zip" files that you can download from the Internet at Wireless Databases page. Also, the FCC's Licensing Support (888-CALL-FCC, select option 2 after recording) is a resource to verify whether a structure is registered.
