  § 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  analog  video  services in the 5925-6425 MHz band or
   14.0-14.5 GHz band provided:

   (1) The application includes certification, pursuant to § 25.132(a)(1), of
   conformance with the antenna performance standards in § 25.209(a) and (b);

   (2) An antenna with an equivalent diameter of 4.5 meters or greater will be
   used for such transmission in the 5925-6425 MHz band, and the input power
   into the antenna will not exceed 26.5 dBW;

   (3) An antenna with an equivalent diameter of 1.2 meters or greater will be
   used for such transmission in the 14.0-14.5 GHz band, and the input power
   into the antenna will not exceed 27 dBW.

   (e) Applications for authority for analog video uplink transmission in the
   Fixed-Satellite Service not eligible for routine licensing under paragraph
   (d) of this section are subject to the provisions of § 25.220.

   [ 58 FR 13421 , Mar. 11, 1993, as amended at  61 FR 9952 , Mar. 12, 1996;  62 FR 5931 , Feb. 10, 1997;  70 FR 32256 , June 2, 2005;  78 FR 8428 , Feb. 6, 2013;  79 FR 8323 , Feb. 12, 2014]
