Figure 6 Compliance Boundary Cylinder
Note: Table 4 shows an example for a typical antenna. As the antenna field
distributions will differ, complete calculations or measurements may
be necessary in order to establish the compliance boundary for other
configurations chosen by the customer. For further information on
calculation methods, see Radio Frequency Electromagnetic Fields.

The cylinder shape overestimates the compliance distances right beside the
antenna. In reality the occupational compliance distance by the side, in line
with the front of the antenna, is less than 0.1 metre for output power levels
below 56 W and less than 0.3 metre for the other power levels reported here.
For characteristics of an antenna recommended for typical configurations of an
RBS 2206, see table below.
