ABSTRACT:
A first radio base station (281) and a second radio base station (282) are co-located at a base station site (20) and share the base station site's common antenna (22). The common (shared) antenna is connected through an amplifier (321) of the first radio base station (which serves as a master amplifier) and an antenna sharing unit50to remaining components (341) of the first radio base station, and also through the master amplifier and the antenna sharing unit to an amplifier (322) and remaining components (342) of the second radio base station. The antenna sharing unit (50), also known as the “coupler”, includes a tower mounted amplifier simulator (64).
