Sec.  97.13   Restrictions on station location.

   (a) Before placing an amateur station on land of environmental importance or
   that  is significant in American history, architecture or culture, the
   licensee  may  be  required  to  take  certain  actions  prescribed by
    Sec.  Sec. 1.13051.1319 of this chapter.

   (b) A station within 1600 m (1 mile) of an FCC monitoring facility must
   protect that facility from harmful interference. Failure to do so could
   result in imposition of operating restrictions upon the amateur station by a
   District Director pursuant to  Sec. 97.121 of this part. Geographical coordinates
   of the facilities that require protection are listed in  Sec. 0.121(c) of this
   chapter.

   (c) Before causing or allowing an amateur station to transmit from any place
   where  the  operation  of the station could cause human exposure to RF
   electromagnetic field levels in excess of those allowed under  Sec. 1.1310 of
   this chapter, the licensee is required to take certain actions.

   (1)  The licensee must perform the routine RF environmental evaluation
   prescribed by  Sec. 1.1307(b) of this chapter, if the power of the licensee's
   station exceeds the limits given in the following table:

                                            Evaluation required if power

Repeater stations (all bands).............  non-building-mounted
                                             antennas: height above
                                             ground level to lowest
                                             point of antenna <10 m
                                             and power >500 W ERP
                                             building-mounted antennas:
                                             power >500 W ERP
------------------------------------------------------------------------
\1\ Power = PEP input to antenna except, for repeater stations only,
  power exclusion is based on ERP (effective radiated power).

   (2) If the routine environmental evaluation indicates that the RF
   electromagnetic fields could exceed the limits contained in  Sec. 1.1310 of this
   chapter in accessible areas, the licensee must take action to prevent human
   exposure to such RF electromagnetic fields. Further information on
   evaluating compliance with these limits can be found in the FCC's OET
   Bulletin Number 65, “Evaluating Compliance with FCC Guidelines for Human
   Exposure to Radiofrequency Electromagnetic Fields.”
