    Default Filtru rejectie pentru CATV

    Salut ! Am nevoie de un filtru trece jos pentru banda CATV cu frecventa de taiere undeva pe la 750 MHz pentru a rejecta canalele test introduse recent de UPC care interfereaza cu niste canale proprii pe care le inserez local. Daca stiti pe unde as putea gasi asa ceva, dati-mi de stire. Am vazut la antech niste filtre Alcad, dar erau de maxim 4 canale si as vrea o banda mai larga de rejectie. Multumesc

    Mersi pentru sugestie, il gasisem la cautari, insa am canale utile pe care vreau sa le pastrez pana la cca 700 MHz, de aici frecventa de taiere specificata de 750 MHz. Am vazut instalat un filtru similar cu ceea ce caut in Chisinau, unde SunTV are banda plina cu DVB-C pana peste 800 MHz

    Incerca pe comanda la Netcom (nci.ro) sau TVK. Poate te rezolva.

    Am incercat la cele doua companii, Netcom are un FTJ dar taie la 583 MHz iar TVK nu comercializeaza/produce filtre.

    Am primit o oferta pentru modelul LP7 750/780, insa la 200 USD (cu livrare in RO) mai caut si altceva.

    Pai omul are cablu de la UPC, iar pe langa asta mai are inserate cateva posturi !Pentru a le putea insera foloseste cate un receptor de satelit +modulator (sau modulatorul din receptorul sat) pentru fiecare post iar iesirile le insumeaza pentru acelasi cablu!
    Nu se pot pune posturi HD pe modulator ci numai SD (semnal modulat vhf-uhf) ,Pt HD iti trebuie HDMI
