PCT No. PCT/FI97/00495 Sec. 371 Date Apr. 28, 1998 Sec. 102(e) Date Apr. 28, 1998 PCT Filed Aug. 27, 1997 PCT Pub. No. WO98/09349 PCT Pub. Date Mar. 5, 1998A method of tuning a summing network of a base station and a band-pass filter provided in such base station. Tuning is performed by arranging a moveable part made of a low-loss dielectric material or ferrimagnetic material in a space between an inner conductor and a tubular conductor in a coaxial cable, the width of the cross-section of the moveable part being different from its length, and tuning the summing network by adjusting the phase angle reflecting from the connector by turning the moveable part about an axle which intersects the cross-section substantially perpendicularly, whereby the distance between the moveable part and the inner conductor and/or between the moveable part and the outer conductor changes.
