3.1.2. Configuration with multiple Antennas

When the configuration consists of multiple antennas and the DAT antenna tuner, it is possible to
operate the antennas either simultaneously or alternately. Simultaneous operation can be
implemented for example use a power splitter and alternating operation using a multiplexer.

3.1.2.1. Configuration with a Power Splitter

Configuration with a power splitter involves at least two antennas being operated simultaneously.
In this case the antenna tuners must have different addresses. Figure 12 shows a configuration
using two antennas connected to the Reader through a power splitter. The antenna tuners have
their own addresses.
