<p>In a branching filter, a transmit filter (14) is divided into first and second transmit filter parts (17, 18). A waveguide branching filter (15) is divided into first and second branching filter parts (19, 20). A receive filter (16) is divided into first and second receive filter parts (21, 22). The first transmit filter part is assembled with the second branching filter part and the second receive filter part. The second branching filter part is assembled with the second receive filter part. The first branching filter part is assembled with the first receive filter part. Alternative assembly is possible. As a further alternative, an installation hole may be formed in the branching filter for removable installation of a cable and be covered with a cover with a packing interposed for hermetic seal and waterproofing. <IMAGE></p> |
