For transmitters rated at a maximum output power not listed above, the
recommended separation distance (d) in feet can be estimated using the
equation applicable to the frequency of the transmitter, where P is the
maximum output power rating of the transmitter in watts (W) according
to the transmitter manufacture.
NOTE 1: At 80 MHz and 800 MHz, the separation distance for the
higher frequency range applies.
NOTE 2: These guidelines may not apply in all situations.
Electromagnetic propagation is affected by absorption and reection
from structures, objects and people.
