The multi-circuit multiple filter ^ units 47 sin '=' uniform designed so that they can accommodate the filter means for three receiving channels. This is how the multi-circuit multiple filter unit 47 according to FIG. 3, for example, can be designed and set for television channels 39, 52 and 58, like the designations Show K39 / K52 and K58. For each receiving channel can the multi-circuit multiple filter unit 47 accommodate three tunable circuits, which by means of the tuning elements 53, 54 and 55 are changeable. Also, every receiving channel is an adjustable attenuation regulator 56 assigned to the multi-circuit multiple filter unit in a box-like elevation 57 of the housing 47 is housed. In the example According to FIG. 3, the multi-circuit multiple filter unit 47 has three input plug-in connections 52 which make the connection of separate antennas and which can be designed as coaxial sockets, for example. Coaxial sockets and coaxial connectors can also be interchanged as plug-in connections and mating connectors;

FIG. 4 shows one with three multi-circuit multiple filter units 47.1, 47.2 and 47.3 equipped antenna amplifier according to the invention. The multi-circuit multiple filter unit

47.1 is e.g. on the UHF television channels K27, K34 and K36, the multi-circuit multiple filter unit 47.2 e.g. on the UHF television channels K21, K24 and K46 and the multi-circuit multiple filter unit 47.3 e.g. on the VHF television channels K5, K9, and K11 coordinated. Thereby are on the multi-circuit multiple filter unit 47.3 only two input plug connections 52 for the connection of two antennas and to the multi-circuit multiple filter unit 47.2 even only one plug connector 52 is provided for connecting a single antenna.

It is easy to see that the top wall of the connection box 44 also has a plug connection and a base 45 for connecting a fourth multi-circuit multiple filter unit 47 can carry. This allows up to twelve reception channels to be selected. Should a different selection of reception channels are made, then without changing the broadband amplifier 32 only other prefabricated ones Multi-circuit multiple filter units 47 are used.
