Recommended Separation Distances for Non-Life Supporting Equipment
Collimator R221/A - R221/A DHHS is intended for use in an electromagnetic environment in which radiated RF disturbances
are controlled. The customer or the user of the collimator can help prevent electromagnetic interference by maintaining a
minimum distance between portable and mobile RF communications equipment (transmitters) and the collimator as
recommended below, according to the maximum output power of the communications equipment.

For transmitters rated at a maximum output power not listed above, the recommended separation distance
d
in metres (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.
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 reflection
from structures, objects and people.
