Aha, 'that more like it.'
The low SNR possibly causing your your more frequent gaps in data?
A stable 11 dB SNR is OK, but not if it's dipping below 10 dB. A slight misalignment in azimuth, elevation or LNB skew reduces the margin, and you may find that the screws holding the mounting into the wall can become loose with time. Mine need tweaking by a fraction of a turn about once a year, and that's just about my limit for reaching up (from a ladder).
