§ 73.158   Directional antenna monitoring points.

   (a) When a licensee of a station using a directional antenna system
   finds that a field monitoring point, as specified on the station
   authorization, is no longer accessible or is unsuitable because of
   nearby construction or other disturbances to the measured field, an
   application to change the monitoring point location, including FCC Form
   302-AM, is to be promptly submitted to the FCC in Washington, DC.

   (1) If the monitoring point has become inaccessible or otherwise
   unsuitable, but there has been no significant construction or other
   change in the vicinity of the monitoring point which may affect field
   strength readings, the licensee shall select a new monitoring point
   from the points measured in the last full proof of performance. A
   recent field strength measurement at the new monitoring point shall
   also be provided.

   (2) Alternatively, if changes in the electromagnetic environment have
   affected field strength readings at the monitoring point, the licensee
   shall submit the results of a partial proof of performance, analyzed in
   accordance with § 73.154, on the affected radial.

   (3) The licensee shall submit an accurate, written description of the
   new monitoring point in relation to nearby permanent landmarks.

   (4) The licensee shall submit a photograph showing the new monitoring
   point in relation to nearby permanent landmarks that can be used in
   locating the point accurately at all times throughout the year. Do not
   use seasonal or temporary features in either the written descriptions
   or photographs as landmarks for locating field points.

   (b) When the description of the monitoring point as shown on the
   station license is no longer correct due to road or building
   construction or other changes, the licensee must prepare and file with
   the FCC, in Washington, DC, a request for a corrected station license
   showing the new monitoring point description. The request shall include
   the information specified in paragraphs (a)(3) and (a)(4) of this
   section, and a copy of the station's current license. A copy of the
   description is to be posted with the existing station license.
