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:
   Wavelength band Evaluation required if power^1(watts) exceeds
   MF
   160 m 500
   HF
   80 m 500
   75 m 500
   40 m 500
   30 m 425
   20 m 225
   17 m 125
   15 m 100
   12 m 75
   10 m 50
   VHF (all bands) 50
   UHF
   70 cm 70
   33 cm 150
   23 cm 200
   13 cm 250
   SHF (all bands) 250
   EHF (all bands) 250
   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

   ^1Power = 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.”
