Search for current Antenna Structure Registration Numbers (ASRNs) within a radius of a latitude and longitude. You can enter coordinates in either the NAD27 or NAD83 coordinate systems.
Archived ASRN records will not be displayed using this search. To locate archived records, use the Registrations button on the ASRN Search Page.
On the results page, click on the blue ASRN number on the left to obtain detailed information about individual registration numbers. Click on the blue "NAD27" link toward the right to convert an ASRN's NAD83 coordinate to NAD27. On the far right of a record, there may also be a link to information related to this tower on the FAA's website.
The "detailed output + CDBS links" options in the AM Query, FM Query, and the TV Query can also be used to find information about local ASRNs. When the detailed output results are displayed, look for a series of links under each station record. The link marked "ASRNs within a 0.5 km radius" will submit the coordinates in that station's record to this ASRN search. You can then change the search radius while maintaining the same center coordinates.
