Beschreibung
Zusammenfassung:	An active distributed antenna system (DAS) is described, including a wide band antenna device having respective transmit and receive antennas disposed in a single package and arranged to provide mutual isolation so that in use noise from the transmit antenna is isolated from the transmit antenna. The system is configured so that wideband reception and transmission are possible without frequency shifting using separate up and down links between antenna and hub.
