Technical Description
For a 1+1 configuration the RAU2 can be fitted directly to an Integrated Power
Splitter (IPS). A similar solution is available for RAU1, using a waveguide
between the power splitter and the antenna.
A symmetrical power splitter version, with equal attenuation in both channels, is
used in the majority of the installations.

The 0.3 m and 0.6 m Integrated dual polarized antennas is used with two RAU2s
and works perfect in combination with XPIC, see Section 4.2.2.11 on page 78.
4.4.2.2 Separate Installation
All antennas have a standardized waveguide interface and can be installed
separately, by using a flexible waveguide to connect to the RAU. The 1.2–3.7
m dual polarized antennas and the 2.4–3.7 m single polarized antennas are
always installed separately.
