Summary: | The invention proposes an LNB using two transposition frequencies chosen on either side of the reception band 200 so as to obtain a transposition of supradyne type 205 and a transposition of infradyne type 204 according to the frequency used. This choice of transposition frequencies makes it possible to have an overlap zone 202 in the middle of the reception band which is transposed with the aid of the two oscillation frequencies but at different frequencies. This makes it possible to choose between the two transpositions in the case where the frequency transposed with the aid of an oscillator corresponds to a particularly noisy frequency. |
