97.13—Restrictions on station location.

(1) The licensee must perform the routine RF environmental evaluation prescribed by § 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
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 § 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.”
