Sec.  74.710   Digital low power TV and TV translator station protection.

   (a) An application to construct a new low power TV, TV translator, or TV
   booster station or change the facilities of an existing station will not be
   accepted if it fails to protect an authorized digital low power TV or TV
   translator station or an application for such station filed prior to the
   date the low power TV, TV translator, or TV booster application is filed.

   (b) Applications for low power TV, TV translator and TV booster stations
   shall protect digital low power TV and TV translator stations pursuant to
   the following requirements:

   (1) An application must not specify an antenna site within the protected
   contour of a co-channel or adjacent channel digital low power TV or TV
   translator station, as defined in  Sec. 74.792.

   (2) The ratio in dB of the field strength of the low power TV, TV translator
   or TV booster station at the protected contour of a co-channel digital TV or
   TV translator station must meet the requirements specified in  Sec. 74.706(d)(1).

   (3) The ratio in dB of the field strength of the low power TV, TV translator
   or TV booster station at the protected contour of a digital low power TV or
   TV translator station on the lower and upper adjacent channels must not
   exceed 49 dB and 48 dB, respectively.

   (4) The analysis used in 74.710 should use the propagation methods specified
   in  Sec. 74.706(c).

   (c) As an alternative to the requirements of paragraph (b) of this section,
   an applicant for a low power TV, TV translator or TV booster may make full
   use of terrain shielding and Longley-Rice terrain dependent propagation
   prediction methods to demonstrate that the proposed facility would not be
   likely to cause interference to digital low power TV or TV translator
   stations, as described in  Sec. 74.707(e) (i.e., reduce the service population by
   no more than 0.5% within the station's protected contour based on the
   interference thresholds of  Sec. 73.623(c) of this chapter).
