§ 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.
