    in principiu cu orice receiver HD care citeste symbolrate sub 1000. mai trebuie avut in calcul si faptul ca latimea de banda a unui transponer nu e mai mare de 1MHz.
    se recomanda receiverul Dr HD.
    se recalculeaza frecventa:
    Frecenta orginala in Banda Ka- Frecventa de oscilatie in banda Ka a lnb-ului + 9750MHz.



    de exemplu :

    21501 MHz - 20250 MHz + 9750 MHz = 11001 MHz
