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.

The nominal maximum power fed to the antenna, as a function of the number
of transceiver units (TRUs) per antenna and the maximum power (including
tolerances and transmission loss) per TRU, for RBS 2106 at 900 MHz and 1800
MHz, are given in Table 6 on page 14.
