Radio and TV receiving aerial array for different bands - feeds multiple range amplifier with different inputs via matching filter

摘要

The radio and television receiving aerial array has a multirange amplifier with separate inputs for different receiving bands. It has several receiving aerials designed to cover different bands. These aerials feed into the appropriate inputs of the amplifier. The multirange amplifier is preceded by a filter with outputs (21-25) equal to and arranged as the number of amplifier inputs (11-15). The filter has several inputs (27-31) with the cables for the different channels, channel groups or sections of bands. The connections are via coaxial plugs and sockets.
