  §  25.205   Minimum angle of antenna elevation.

   (a) Earth station antennas shall not normally be authorized for
   transmission at angles less than 5DEG 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
   3DEG and 5DEG in the pertinent directions. In certain instances, it may
   be necessary to specify minimum angles greater than 5DEG because of
   interference considerations.

   (b) ESVs making a special showing requesting angles of elevation less
   than 5DEG 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 § 25.204(h) and (i).

   (c) VMESs making a special showing requesting angles of elevation less
   than 5DEG measured from the horizontal plane to the direction of
   maximum radiation pursuant to (a) of this section must still meet the
   EIRP and EIRP density towards the horizon limits contained in
   § 25.204(j).
