A band pass-band reject filter in which the filter housing which comprises the resonant cavity is contained within an annular wall that is supported at each end by an end plate. The filter is connected to an instrument rack or the like by the distal ends of bolts which extend between the end plates and which lie closely along side the annular wall. The end plates are soldered to the annular housing. The bolt heads are soldered to the end plate and their shafts are soldered to the side wall.
