It is provided a method for configuring abeam direction of a set of antennas of an antenna site for a radio communication system. The method being performed in a beam direction configurer and comprises the steps of: obtaining a desired beam direction; configuring a coarse beam director, being configurable to provide only a fixed number of beam directions for the set of antennas, to provide a beam direction being closest to the desired beam direction; and configuring a fine beam director, being configurable more finely than the coarse beam director, to be in a fine beam direction such that a resulting beam direction for set of antennas, being a combination of the beam direction of the coarse beam director and the fine beam director, corresponds to the desired beam direction.
