    Default Problema LNB?

    Am lipsa semnal pe 12015 H pe toti satelitii. Pe vertical merge.
    LNB-ul e twin, problema e pe ambele iesiri, asa ca exclud receptoarele.
    A-ti mai intalnit asa ceva?

    E Inverto 0.3dB, are peste 3 ani, iar cand mai da caldura vreau sa-l schimb. A aparut ceva nou pe piata demn de mentionat?

    E posibil ca si atenuarea la anumite frecvente este alta , din cauza ripple-ului de pe cablu. Apoi si caracteristica LNB-ului este neliniara si la anumite frecvente poti avea semnale putin diferite, din cauza VRWR-ului. Daca ai antena turtita un pic si din cauza aia poti sa ai la anumite frecvente o cadere de semnal . Incearca un alt cablu de coborare de la LNB...
