    Intelsat 805 at 55.5°W

    aici aveti lista frecventelor receptionabile de pe acest satelit
    am folosit urmatorul echipament :antena pfa 1.80m,lnb ESX241,placa TBS 6925,madrid-spania








    ATENTIE:
    polaritatile din lista sant inversate
    (am rasucit lnb in fel si chip dar tot asa am receptionat, si apare doar la sateliti cu polarizare circulara horizontal-vertical)

    Bafta oricum

    asa este se poate prinde ntv+ daca pui o plcutza de plastic eu am postat demult pe diverse formuri ... am explicat cum poti face dintr-un lnb cu "flanse unul circular atit se poate prinde retinet-i si banda KU ... exact cu antena de 1.8 am semnal util si pe banda ku si circular vad rusi cu semnal bun si banda kuuuuuu seara fina alll

    a aparut un nou model de lnb in banda C al producatorului Titanium Satellite --Wideband Version (3.4 - 4.2Ghz)--
    Coming next february , Version (C1W-PLL) from 3.4 - 4.2GHz available

    C1-PLL C-band LNBF Single

    Interntional Customers: Wideband Version (3.4 - 4.2Ghz) Available February 2014

    The C1-PLL Phase Lock Loop C-band LNBF technology provides exceptional reception of weak satellite signals and the most demanding high FEC S2 channels. Designed to meet the requirements for light commercial applications and the most demanding satellite hobbyist, it is cost-effective, high quality and professional grade. The C1-PLL polarity is voltage switched for receiving horizontal / vertical linear or right / left circular (with the included dielectric slab). It includes a flat scaler designed for prime focus dish types and fits the industry standard 68mm scalar mounts and the optional Titanium conical scalar for offset type dishes.

    Regular LNBFs typically last only five to seven years. DRO type LNBFs lose performance over time as the mechanically tuned frequency slowly drifts until one day, the receiver is no longer capable of tuning the satellite channels. PLL LNBFs do not rely on a mechanical tuning slug that may shift off frequency due to physical damage or aging. PLL LNBFs have a crystal oscillator that will remain tuned exactly on frequency. The C1-PLL frequency is +/-50KHz and typically the operational drift to be within +/- 10KHz.

    The heavy aluminum casting, snow white poly coating and cooling fins assist with keeping the C1PLL operational temperature low and running cool. These thermal control features increase the C1-PLL performance and stability, insuring many years of reliable service.

    Titanium Satellite provides a Lifetime Warranty on the C1PLL against frequency drift! If you are not completely satisfied with the performance of the Titanium C1PLL, we will promptly refund your purchase!

    Thumbs up

    test realizat cu mai multe lnb-uri in banda C la receptia satelitului SES 6@40,5W



    Nota:

    pe unele frecvente semnalul receptionat fluctueaza cu o intensitate mare sau mica
    lnb ESX-241
    indiferent ce pozitie/variante as adopta NU receptionez polaritatea orizontala respectiv ( L )
    1.-pozitionarea placutei fermecate intre cele doua sonde se pot receptiona ambele polaritati
    2.-pozitionarea placutei fermecate deasupra celor doua sonde se pot receptiona numai o singura polaritate respectiv verticala ( R )

    practic diferentele dintre lnb sant foarte mici ,iar diferentierea se poate face doar atunci cand receptionam semnale slabe pe unele frecvente slabe (gaseste/memoreaza/reda fara discutie

    Se pare ca interesul pentru banda C a cam scazut, desi mai sunt destule pozitii ce ar putea prezenta interes pentru pasionati.
    O pozitie preferata de mine este 20E, ArabSat 5C cu destule programe FTA interesante.
    Apoi pozitiile 5W sau 26E, plus altele in sectorul estic pentru vorbitorii de limba rusa.

    ------------------------------------------
    mai jos aveti impresiile a doi pasionati care detin/folosesc acest model de lnb

    I am happy to report that after mounting a new c-band LNB with a 5G filter builtin has stopped the interference to my parents AsiaSat-5 TVE reception.


    Mediastar and Satking now supply these LNB's for $100

    Thanks all for your help.

    regards
    Joe

    Thanks vk5ei, I’ve found it for $70 at DIY TradeTech in Victoria - postage would be additional.

    anul trecut va informam pe acest forum despre aparitia unui lnb care este prevazut cu un filtru antiferenta 5G.
    in perioada urmatoare se vor efectua testele de rigoare pentru a vedea eficienta sa
    acest lnb a fost comandat de pe ebay .com.au si a costat 450+79lei vama (pasiunea costa prieteni stiu de ce )
