1. Regulation
47 CFR §1.1310 Radiofrequency radiation exposure
Table 1. LIMITS FOR MAXIMUM PERMISSIBLE EXPOSURE (MPE)
(A) Limits for Occupational / Controlled Exposure
Frequency range [MHz] Power density [mW/cm2] Averaging time [minutes]
1,5000-100,000 5.0 6

2. Result
Power density of NKE-2255-6HS, NKE-2255-7 and NKE-2255-9 are satisfied MPE limits
(5.0mW/cm2) in all region.

Calculated Maximum power density in all region
NKE-2255-6HS NKE-2255-7 NKE-2255-9
1.348 mW/cm2 0.934 mW/cm2 0.576 mW/cm2
