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 metres for output power levels
below 56 W and less than 0.3 metres for the other power levels reported here.
For characteristics of an antenna recommended for typical configurations of
RBS 2106, see table below.
