PURPOSE:To switch a complicated feeding system of a repeating amplifier to various feeding systems by providing a switching terminal separating a different feeding system. CONSTITUTION:Among feeding system switching terminals B1, B2, B3 and B4 connected respectly to plural branching and distributing terminals BR1, BR2, BR3 and BR4, of a CATV repeating amplifier 1, between feeding system switching terminals B1 and B2, and B3 and B4 for constituting different feeding systems, a separating switching terminal B5 which can separate those feeding systems is provided. When the separating switching terminal B5 is made open, the feeding system switching terminals B1 and B2, and B3 and B4 are separated, therefore, the feeding system extending from the branching and distributing terminal BR1 to BR2, and the feeding system extending from the branching and distributing terminal BR3 to BR4 become independent feeding systems.
