distance din metres (m) can be determined using the equation applicable to the frequency of the
transmitter, where Pis the maximum output power rating of the transmitter in watts (W) according
to the transmitter manufacturer.
At 80 MHz and 800 MHz, the separation distance for the higher
frequency range applies.
These guidelines may not apply in all situations. Electromagnetic
propagation is affected by absorption and reflection from structures,
objects and people.
