    Ma puteti lamuri si pe mine care e diferenta intre LNB-uri cu factor de zgomot 13K, 15K si 17K.
    Si eu banuiesc ca nu e mare - dar cine stie poate, poate.

    O mica adaugire la antena care a lipsit din pachetul initial...si s-a rezolvat si problema de semnal pe anumite transpondere DVB-S2
    Sa nu iti vina sa crezi ce poate sa faca o tava quiche pentru semnalul C band.

    cel mai bun este 13, dar doar daca e si real. in ziua de azi e cam greu de gasit unul cu buletin de masura.

    Asa arata in poza de mai sus.

    O sa incerc sa mai reglez la LNB skew pentru polarizarea H. Dar pentru prima data sunt foarte multumit de rezultate.

    Pentru a scoate in evidenta mai bine transponderii gasiti de Crazyscan e bine sa debifezi "Markwith" din Style.
    Pentru cei care nu stiu(nu e cazul tau),Crazyscan genereaza lista de transponderi gasiti la cautarea oarba in orice format,cu mai multe optiuni(snr,db,etc),la alegere,pentru dispozitivul si/sau aplicatia dorita,ca in exemplu de mai jos.

    ps_ai o antenna de C-band de invidiat,cel putin de mine.Sa ia rezultate pe masura!

    SEAVEY - C/KU Band Feed
    Das Beste an Combi-Feeds
    First introduced to the satellite communications industry in 1982, Seavey Engineering’s dual band antenna feeds are now the accepted standard. They simultaneously access all downlink signals from hybrid satellites.

    Dual band feeds operate over the standard frequencies of 3.7 - 4.2 GHz in C-band and 10.7 - 12.75 GHz in 500 MHz bandwidths. Both two-port and four-port versions are offered with a wide range of options.

    Seavey Engineering’s dual band feeds have been used on thousands of commercial and consumer TVRO antennas for many years attesting to the reliability and efficiency of the patented (see Note) design.
    Because of this success, mounting and interface adaptors are available for many reflector manufacturers’ standard products. Therefore, when ordering, please specify the reflector you plan to use.

    Basic feeds use a concentric circular waveguide at Ku-band and an overmoded coaxial waveguide operating at C-band. Models with two ports use the patented polarization rotation probe system found on other Seavey Engineering feeds. A single small motor rotates the plane of polarization to match the satellite.

    Lnb-urile in banda Ku se pare ca sunt 2 cu cite o polaritate fiecare, unul pentru orizontala si altul pentru verticala fiind modele vechi.
    ar trebui intrebat inainte de a comanda

    Dupa teste de vara...si utilizarea comparativa a lnb-ului PLL primit din Asia am ajuns la concluzia ca utilajul nu poate mai mult.
    iar pentru ca am ales prima data CW2-PLL este cel mai bun LNB care se gaseste pentru antena mea.
    Acesta reuseste sa deschida semnale pe care produsul conceput in Asia nu le miroase.

    Daca ar fi sa pun un DRO LNB cu ditamai Feed Hornul, posibil sa gasesc antena distrusa la un vant mai puternic.
    Antenele astea cu paneluri nu sunt concepute pentru perfomanta ci doar pentru utilizare de durata scurta.

    P.S. In 2-3 ani se va instala rugina, desi am inceput deja mentenanta cu vaselina la suruburi, jointuri.
    Un spray cu email alb intotdeauna la indemana pentru a acoperii zonele cu risc de rugina.
