Sec. 21.107  Transmitter power.

    (a) The power which a station will be permitted to use in these 
services will be the minimum required for satisfactory technical 
operation commensurate with the size of the area to be served and local 
conditions which affect radio transmission and reception. In cases of 
harmful interference, the Commission may, after notice and opportunity 
for hearing, order a change in the effective radiated power of a 
station.
    (b) The EIRP of a transmitter station employed in this radio service 
shall not exceed the values shown in the following tabulation:

                                                               Maximum  
                                                              allowable 
                                                              EIRP for a
                   Frequency range (MHz)                        fixed   
                                                               station  
                                                               (Watts)

2,150 to 2,162.............................................     \1\ 2000
2,596 to 2,680.............................................    \1\ 2000 
------------------------------------------------------------------------
\1\ When a Multipoint Distribution Service station uses a non-          
  omnidirectional antenna EIRP up to 7943 Watts may be authorized       
  pursuant to Sec.  21.904(b) of this Part.
