Picture quality has nothing to do with LNB. I mean, if you have acceptable signal level, the quality of the picture will be the same.the picture quality gone very sharp.
yes, quality is down to how the receiver renders the image. my zgemma looks slightly blurred compared to my octagon sx88 - signal strength always roughly the same in DB (decibels) on both. im actually thinking about ditching the zgemma H7s - i only bought it for the 3 tuners, now theres not much need for a dvb-c cable tuner. it doesnt remove channels when you run a channel scan, very irritating.Picture quality has nothing to do with LNB.
