Just fitted my new LNB and before I did so, I made a note of some of the SNR/AGV for various channels to compare them.

What's odd is that in most cases the signal strength has gone up a fair bit, but the signal quality is up on a few and down on a few.

All working 100% fine, just found it a little off that with a lot more signal strength, i was getting less quality on some channels (although was also getting more on others), just curious thats all

A few examples

meant to say I found it a little odd, not a little off

The only way to really test is with a installers meter tbh. I think receivers can be a bit unreliable for readings of this sort. An installers meter is calibrated.
