    Default antena prime focus - 2 LNB ?

    poate cineva dintre voi a incercat sa monteze 2 lnb pe o antena circulara ptr. 2 sateliti apropiati , ex:
    - Hotbird si
    -5 gr. E ( ptr. max TV)

    merge ? sau rezultatele sunt nesatisfacatoare ?
    antena = 1.2 m zona = constanta lnb= no name ... cica 0.2 db

    cel care a comandat antena ... binenteles ca nu s-a gandit la un off-set care stiu ca merge

    recomandari

    Numai bine

    teoretic ar trebui sa mearga.practic o antena mai mare ar garanta reusita.

    Fizic vorbind si eu cred ca ar trebui sa mearga. La prime focus insa, ce pui in focar iti umbreste parabola spre deosebire de offset. Asa ca punind montura la LNB-uri si mai mai multe LNB-uri s-ar putea sa se piarda ceva din semnal

    Eu am tot o parabola de 1,2 m dar pe combinatia Astra in focarul antenei si HotBird in focar secundar si merge toul bine, in zona Arges.

    Ok ! am inteles
    deci teoretic pierderea nu ar fi mare chiar daca al doilea lnb ar umbri ceva din antena , singura problema este sa-i gasesc pozitia optima celui de-al doilea lnb
    avand in vedere ca max se receptioneaza si cu 0.9 m ....cred ca merge ...numai ca o sa fie ceva de munca pina fixez al doilea lnb

    multumesc

    Default 2 lnb

    Poti sa folosasti si lnb-uri de ofset, mai putin cel din centru. ca sistem de prindere poti folosi sistemul de ofset pentru 2 lnb-uri care se gaseste in comert. antena mea este cu focarul central pe astra. al 2 lnb este pentru hotbird montat in dreapta (cum te uiti din fata antenei) la marginea exterioara a sistemului de prindere(antena are 1,5m) putin mai jos decat lnb-ul principal(1cm) si rotit dreapta 10 grade. lnb-ul este invacom ofset (am economisit bani fiind mai eftin decat cel cu flansa).Nu am sesizat pierderi, chair cu invacomul am semnal mai bun. nu am reusit din prima asa ca nu dispera, o sa te chinuiesti cateva ore. succes!

    Ideea e chiar foarte buna . Petntru LNB-ul care nu e in focarul principal antena devine offset.
