Sec.  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
    Sec. 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  Sec. 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  Sec. 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  Sec. 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  Sec. 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  Sec. 25.211(d), must comply with the procedures set
   forth in  Sec. 25.220.
