§  25.211   Analog video transmissions in the Fixed-Satellite Services.

   (a) Downlink analog video transmissions in the band 3700-4200 MHz shall
   be transmitted only on a center frequency of 3700+20N MHz, where N=1 to
   24. The corresponding uplink frequency shall be 2225 MHz higher.

   (b) All 4/6 GHz analog video transmissions shall contain an energy
   dispersal signal at all times with a minimum peak-to-peak bandwidth set
   at whatever value is necessary to meet the power flux density limits
   specified in §  25.208(a) and successfully coordinated internationally
   and accepted by adjacent U.S. satellite operators based on the use of
   state of the art space and earth station facilities. Further, all
   transmissions operating in frequency bands described in §  25.208 (b)
   and (c) shall also contain an energy dispersal signal at all times with
   a minimum peak-to-peak bandwidth set at whatever value is necessary to
   meet the power flux density limits specified in §  25.208(b) and (c) and
   successfully coordinated internationally and accepted by adjacent U.S.
   satellite operators based on the use of state of the art space and
   earth station facilities. The transmission of an unmodulated carrier at
   a power level sufficient to saturate a transponder is prohibited,
   except by the space station licensee to determine transponder
   performance characteristics. All 12/14 GHz video transmissions for
   TV/FM shall identify the particular carrier frequencies for necessary
   coordination with adjacent U.S. satellite systems and affected
   satellite systems of other administrations.

   (c) All initial analog video transmissions shall be preceded by a video
   test transmission at an uplink e.i.r.p. at least 10 dB below the normal
   operating level. The earth station operator shall not increase power
   until receiving notification from the satellite network control center
   that the frequency and polarization alignment are satisfactory pursuant
   to the procedures specified in §  25.272. The stationary earth station
   operator that has successfully transmitted an initial video test signal
   to a satellite pursuant to this paragraph is not required to make
   subsequent video test transmissions if subsequent transmissions are
   conducted using exactly the same parameters as the initial
   transmission.

   (d) An earth station may be routinely licensed for transmission of full
   transponder video analog services provided:

   (1) In the 5925-6425 MHz band, with an antenna equivalent diameter 4.5
   meters or greater, the maximum input power into the antenna does not
   exceed 26.5 dBW; or

   (2) In the 14.0-14.5 GHz band, with an antenna equivalent diameter of
   1.2 meters or greater, the maximum input power into the antenna does
   not exceed 27 dBW.

   (e) Antennas smaller than those specified in paragraph (d) of this
   section are subject to the provisions of §  25.220, which may include
   power reduction requirements. These antennas will not be routinely
   licensed for transmission of full transponder services.

   (f) Each applicant for authorization for analog transmissions in the
   fixed-satellite service proposing to use maximum power into the antenna
   in excess of those specified in §  25.211(d), must comply with the
   procedures set forth in §  25.220.
