    Default probleme frecventa antena1

    Am un prieten care are o firma de CATV si are mari probleme pe frecventa la antene si anume la anumite perioade de obicei pe la ora 12-13 pica semnalul pe la 35-40% calitate iar cand este ok are 85%. A schimbat antena , lnb si cablu si aceeasi problema , sa fie din cauza ca aproape de head-end este o unitate militara de graniceri?

    Salut. In zilele acestea se simte prezenta fenomenului sun outage. Mai multe pe http://www.rdi-board.com/showthread....ght=sun+outage si pe http://www.satellite-calculations.co...lc/SUNcalc.htm (se alege satelitul si locatia-orasul sau se trec coordonatele in tabel). Numai bine.

    Eu am avut probleme cu o antena GSM din cauza careia semnalul era mai slab pe anumite frecvente.Am reusit sa o rezolv destul de simplu: am imbracat in staniol LNB-ul mai putin partea din fata.
    Asta daca nu e efectul sun outage descris mai sus.
