Protected Microwave Frequency Information Search

The Protected Microwave Frequency Information Search identifies protected licence holders who may be using frequencies within the band specified, in the general geographic area indicated. It is purposefully vague, to protect the confidentiality of the users, but will provide searchers with sufficient information to contact all potential protected licence holders within the area of concern.

Searches take into account both existing frequency records, and pending frequency records (that is, if an application has been received for use of a frequency, that frequency will be marked as unavailable for the purposes of your search).

Unlike the other search tools, you are not given the option to select fields to display on the results page. The results page displays the frequency owner and contact information only. Technical information is not available.
