   A station licensed with a directional antenna pattern pursuant to a
   proof of performance using moment method modeling and internal array
   parameters as described in § 73.151(c) shall recertify the performance
   of the antenna monitor sampling system only in the case of repair to or
   replacement of affected system components, and then only as to the
   repaired or replaced system components. Any recertification of repaired
   or replaced system components shall be performed in the same manner as

   measurements shall be retained in the station's public inspection file.
