Exler Ralf, Linke Christian, Flinner Udo: Twin converter. Kathrein Werke Kg, June 26, 2002: EP1217836-A2 (1 worldwide citation)

The design of the twin converter assembly (4) permits reception of programs radiated by another satellite station, when it forms part of a multifeed system, while the assembly contains an extra input (C) in addition to its two outputs (A,B). The extra input is of the loop-through type so activated b ...
