Table 206 – Recommended separation distances between portable and mobile
RF communications equipment and the bathtub classic line -
for EQUIPMENT and SYSTEMS that are not LIFE-SUPPORTING (see 6.8.3.201 b))
portable and mobile RF communications equipment and the bathtub classic line
The bathtub classic line is intended for use in an electromagnetic environment in which radiated RF disturbances are
controlled. The customer or the user of the bathtub classic line can help prevent electromagnetic interference by
maintaining a minimum distance between portable and mobile RF communications equipment (transmitters) and the
bathtub classic line 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.
