Search for current Antenna Structure Registration Numbers (ASRNs) within a radius of a latitude and longitude.  You may 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.  Towers without current Antenna Structure Registration Numbers will not be included.

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 coordinates to the NAD27 coordinate system.  On the far light of a record, there may also be a link to related information from the FAA's web site.

The "detailed output + CDBS links" options in the AM Query, FM Query, and the TV Query may 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 record to this ASRN search.  You may then change the search radius while maintaining the same center coordinates.
