   Link to an amendment published at  70 FR 19309 , Apr. 13, 2005.

   Fixed transmitters for point-to-point operation must use a directional
   transmitting antenna with the major lobe of radiation in the
   horizontal plane directed toward the receiving antenna or passive
   reflector of the station for which the transmissions are intended.
   Directional antennas used in the Public Mobile Services must meet the
   technical requirements given in Table C-2 to Sec. 22.361.

   (a) Maximum beamwidth is for the major lobe at the half power points.

   (b) Suppression is the minimum attenuation for any secondary lobe
   referenced to the main lobe.

   (c) An omnidirectional antenna may be used for fixed transmitters
   where there are two or more receive locations at different azimuths.
