    Default Valori EIRP

    Aici http://www.satlex.ro/ro/eirp_values_ku_band.html e dat un tabel cu EIRP vs. dimensiunea antenei pt. un LNB 0,7 dB.

    Cat se poate castiga la dimensiunea antenei folosind un LNB de 0.2 - 0.3 ?

    Nu foarte mult , iar daca 0.7 e profesional , chiar putin in comparatie cu multe 0.2 , 0.3 no name .


    P.S. Apropos de EIRP . Am vazut o harta de acoperire cu un spor de 61 dbW pe Japonia . Cea mai mare valoare care este oferita entru transmisiuni publice . Asta inseamna cu un LNB bun , o antena de 25 cm , poate si mai mica .

    Asa e, am mai cautat si eu: http://www.flysat.com/dish.php
    Si aici, 0.6-0.7 dB e valoarea minima pt LNB.

    Asta ma face sa cred ca cei 0.2db sunt similari cu 2000 W ai unui difuzor de camera


    PS @*********: parca am mai vazut televizorul tau, si prin alta parte, destul de recent lansat E adevarat, prindea alt canal

    PS2: Am si eu televizor:
