Abstract
A connection unit comprising a feeder port for connecting the connection unit to an antenna feeder, a first relay port for connecting the connection unit to a receiving and transmitting port of a first base station, and a second relay port for connecting the connection unit to a diversity receiver port of a second base, wherein the connection unit comprises a directional coupler for separating signals where a signal in the feeder port is divided into a first output signal in the first relay port of the first base station and a second output signal in the diversity receiver port of a second base station. A signal in the first relay port is, however, passed undivided to the feeder port. Diversity may be selectively provided in the receiving direction, but substantially no additional loss is introduced to the main transmission direction.
