Recommended separation distances
Recommended separation distances between portable and mobile RF
communications equipment and the Burdick 8300/8500
The Burdick 8300/8500 is intended for use in an electromagnetic environment in
which radiated RF disturbances are controlled. The customer or the user of the
Burdick 8300/8500 can help prevent electromagnetic interference by
maintaining a minimum distance between portable and mobile RF
communications equipment (transmitters) and the Burdick 8300/8500 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.
NOTE1: 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.
