Ho un motorizzato montato da solo. Qualche ritocco al puntamento potrei farlo. Comunque aspetto. Anche perche' in garage ho gia' una 120 pronta...thepictors2 ha scritto:

Ho smontato oggi una centralizzata ormai inutile, le sue dimensioni sono si 100x110. Troppo grossa per il mio motore attuale, e poi ha il supporto lnb rotto.
Ma a questo punto mi conviene prendere una 125 nuova più leggera e lo staab o similare. Devo solo verificare la messa a piombo dell'attuale supporto, che non mi sembra perfettissimo, ma era nato per una padella 180 in vetroresina degli anni 80 ... (già smaltita) non si stacca neppure con un uragano.

Some important info regarding reception Astra 2F
Spero sia di interesse ...
Dal forum di www.astra2.org
I've done some research and as you know the coverage for Astra 2F is rather disappointing for many of us, however don't give up now, there are some bright spots i want to declare.
Current transponder they switched, 11024H, on Astra 2F is broadcasting in 8PSK modulation, all other transponders broadcasting TV services usually broadcast in QPSK modulation which is true for the rest of the 28.2E position.
This what gets interesting, 8PSK requires more signal to deliver the same performance as QPSK, which means, if this transponder 11024H is only for testing purposes this means the other 2F transponders will most probably be broadcasted in QPSK.
I have some information from a tech document from Tandberg that shows what C/N values are reguired for a stable QEF (Quasi Error Free,picture not pixelating)
As you can see from diagram a FEC of 2/3 tell us that QPSK requries 4.36dB for QEF and 8PSK requires 8.12dB for QEF
This says it all, the difference is huge which means the current transponder needs 8.12-4.36dB which means you need 3.76dB more at 8PSK modulation to give a pixelated free picture(QEF)
That is the reason the carrier is so low to the rest of 1N transponders as it's broadcasting in 8PSK.
