Recommended Separation Distances
Recommended separation distance between portable and mobile RF communications
equipment and the HBP-9020
The HBP-9020 is intended for use in an electromagnetic environment in which radiated RF disturbances
are controlled. The customer or the user of the HBP-9020 can help prevent electromagnetic interference
by maintaining a minimum distance between portable and mobile RF communications equipment
(transmitters) and the HBP-9020 as recommended below, according to the maximum output power of the
communications equipment.
Rated maximum
output power of
transmitter in watt
Separation distance according to frequency of transmitter in meter
150 kHz to 80 MHz
d = 1.2
80 MHz to 800 MHz
d = 1.2
800 MHz to 2.5 GHz
d = 2.3
0.01 0.12 0.12 0.23
0.1 0.38 0.38 0.73
11.21.22.3
10 3.8 3.8 7.3
100 12 12 23
For transmitters rated at a maximum output power not listed above, the recommended separation
distance d in meters (m) 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 manufacturer.
Note1: At 80 MHz and 800 MHz, the separation distance for the higher frequency range applies
Note2: These guidelines may not apply in all situations. Electromagnetic propagation is affected by
absorption and reflection from structures, objects, and people.
