    Default LNB offset

    Care este diferenta intre un LNB pentru o antena circulara si una offset ?

    era o vreme cind ai fi primit sfat de la cel putin trei mesteri sa pui mina si sa folosesti functia search.

    Diferenta consta in feedhorn ajustat in asa fel incat sa optimizeze capturarea reflexiei undei din antena in LNB.
    Oamenii se nasc si mor, fara ca macar sa aibe idee unde se afla cu adevarat si care e sensul existentei.

    @nirolf ai foarte mare dreptate ... pacat ca acum atentia maestrilor e prea mult acaparata de DTH si aspectele lui comerciale. Stiam de raspunsul lui mihaip dar eu vroiam ceva mai amanuntit, de ce apar diferente constructive asa mari ale ghidului de unda de la un LNB la altul ?

    Exista diferente datorita faptului ca cele doua reflectoare sint vazute de LNB sub unghiuri diferite,la offset unghiul e mai mic decit la parabola
    clasica.
