78% signal quality on silvercrest receiver

    New to this so forgive silly questions.
    I've got a lidl 80cm dish and receiver dvb-s sl65.
    It's on astra 28e and i cant improve signal intensity above 78%.
    Signal quality similiarly fluctuates between 70 and 76%.
    I'm using the white coax supplied and have an uninterrupted view of the sat in the sky.
    I've all good connections on the f connectors and the cable run is relatively short through the attic with less than a metre outdoors.
    Is it this cheap coax thats causing my poor signal?

    Don't know if it helps but here is the other info up on the info screen:
    LNB freq 9750 10600 Video PID 5600
    Trans freq 10818 Audio PID 5601
    Symbol rate 22000 PCR PID 5600
    Polarity V Text PID 5603
    Diseqc 2/4 Sub PID 5604
    Version: 1084h-C65gb.

    I've tweaked the dish over and over but these are the best results i can manage.
    Any ideas what I'm doing wrong?

    The level is fine; if you were dropping into the low 50's or 40's, you'd begin to see the picture pixelate, but at nearly 80%, you're flying.

    I'd expect it possible to get a bit higher with a top-end LNB, but for getting 28E in Ireland, not worth the effort (maybe if you were trying to get 26E on a 1m dish it would be more important).

    Also, have you played with the lnb skew to maximise the signal further?

    Also, the frequency you quoted (10818 V) is one of the stronger transponders on 28.2E. To be sure you're getting the best out of the dish, you want to be making sure that you're getting the weaker transponders on Eurobird at 28.5E. If I ever need to set up a dish, I maximise the signal on a channel such as Zone Horror, or some of the Movies4Men channels. If you can get them up into the high 70's or 80's, you've probably got it as good as you can get it.

    LNB Skew can vary quality from 100% to zero.

    Thanks for that.
    Yes i'm pretty sure i've the best possible lnb skew.
    I might try upgrading the lnb.
    I've had the set up unopened up in the attic for the last 3 years.
    Gettin a bit of fun out of it now.

    Not worth it.

    Also "quality" meters on stbs are not very accurate.

    If it's above 55% and no channels pixelate it's fine.
