    Default Saorsat KA-BAND

    La pozitia orbitala 9.0°E exsita un satelit Eutelsat Ka-Sat 9A care transmite in banda KA, iar acolo pe frecventa 20185 cu polaritate circulara L se transmite FTA pachetul televiziunii publice irlandeze Saorsat format din 5 canale: RTÉ One, RTÉ Two, RTÉ News Now, RTÉ Jr si RTÉ One +1 plus 10 posturi de radio.

    Cum se receptioneaza aceasta banda ? Ce este cu ea ?

    pai eu il receptionez cu o antena de 80cm si lnb in banda KA. ei au lansat Saorsat pentru a acoperi din satelit ceea ce nu acopera emitatoarele digital terestru ale Saorview.Tot de la aceeasi pozitie orbitala am internet prin satelit two way de la Onwave.

    eu am luat unul twin cu 27 euro de pe www.tvtrade.ie .
    Saorsat nu l-am incercat in Romania dar instalatia de internet prin satelit two way de la Onwave merge perfect in Romania.Poate doar spoturile pt tv prin satelit acopera doar Irlanda.Merita incercat.

    http://www.saortv.info/satellite-saorsat/

    Reception will be possible with an HD Satellite receiver (but not a Sky branded Model), but a different kind of LNB and dish to that used for Freesat or Sky is required, likely an 80cm dish. A second dish is possible for those with existing dish, or a large “dual feed” or “multi-feed” dish for those getting a new install including Freesat and/or Sky as well as Saorsat.

    The LNBF needs to be Left Circular Polarised for Ka-Band (20.185GHZ). Suitable LNBF became available during February 2012

    LNB trebuie sa stie polarizare circulara stanga pentru banda Ka (20.185 GHZ).

    Detalii tehnice:

    Saorsat tests have been reported on Lyngsat and boards.ie by Apogee

    Ka-sat @ 9E
    20.185GHz, Left Circular Polarisation
    DVB-S2 QPSK
    SR 25000 with 1/2 FEC
    Irish Spot (there are 82 spots on Ka-Sat)

    Nu cred ca se poate receptiona la noi din cauza ca are spoturi foarte mici, si se pot reutiliza frecventele, ca si la telefonia mobila. O frecventa se poate reutiliza pentru servicii diferite dar in celule care nu sant adiacente.

    http://www.eutelsat.com/satellites/E...KA-SAT-9A.html

    Aici se pot vedea celulele, la extremele hartii de acoperire, sant cam cat suprafata Romaniei:

    http://www.eutelsat.com/satellites/E...-coverage.html

    In plus antena trebuie sa aiba suprafata foarte precisa, cu iregularitati sub ±0.2 mm ...
