System Overview
2.4 Outdoor Part
The outdoor part is supplied for various frequency bands. It consists of an
antenna, a Radio Unit (RAU) and associated installation hardware. For
protected (1+1) systems, two RAUs and one or two antennas are used. When
using one antenna, the two RAUs are connected to the antenna using a power
splitter.
The RAU and the antenna are easily installed on a wide range of support
structures. The RAU is fitted directly to the antenna as standard, integrated
installation. The RAU and the antenna can also be fitted separately and
connected by a flexible waveguide. In all cases, the antenna is easily aligned
and the RAU can be disconnected and replaced without affecting the antenna
alignment.
The RAU is described in Section 4.3 on page 69.
The antennas are described in Section 4.4 on page 76.
