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).
