What are the factors that affect the Signal Quality reading?
I have a second hand Sky Digibox. I use it only for free-to-air channels and use CNN for testing as it appears to have a low output. When I connect to the “minidish” I see 70% signal strength and 30% signal quality. When I connect to an 80cm dish (0.6dB LNB) I see 60% signal strength and 40% quality!
