Configuration III
Two dual polarized duplexed antennas with duplex filters in BTS. Power fed via
single port Current Injectors. Instead of using e.g. one 8-ch. combiner, two 4-ch.
combiners can be used, distributing the Tx-signals over two Duplex antennas. The
insertion loss and power handling (heat sink & peak power) will be more
advantageous. A Duplex TTA could be preferred in stead of the Receive-only TTA as
this will prepare the system for a build out with another transceiver.
