For transmitters whose maximum nominal output is not indicated in the above table, the distance can be calculated using the equation in the

column, where P is the maximum nominal output of the transmitter in Watts (W) according to the transmitter’s manufacturer.

Note: The higher frequency range applies at 80 MHz and at 800 MHz.

Note: These guidelines may not be applicable in all cases. The propagation of electromagnetic values is affected by absorption and reflection

by structures, objects and people.
