Sec.  25.205   Minimum angle of antenna elevation.

   (a) Earth station antennas shall not normally be authorized for transmission
   at angles less than 5 ° measured from the horizontal plane to the direction
   of maximum radiation. However, upon a showing that the transmission path
   will be seaward and away from land masses or upon special showing of need
   for lower angles by the applicant, the Commission will consider authorizing
   transmissions at angles between 3 ° and 5 ° in the pertinent directions. In
   certain instances, it may be necessary to specify minimum angles greater
   than 5 ° because of interference considerations.

   (b) ESVs making a special showing requesting angles of elevation less than
   5 ° measured from the horizontal plane to the direction of maximum radiation
   pursuant to (a) of this Section must still meet the effective isotropically
   radiated power (e.i.r.p.) and e.i.r.p. density towards the horizon limits
   contained in  Sec. 25.204(h) and (i).
