Same here, except with my Roamio the SNR is showing at 44db.
The cable card that pairs fine in the Premiere won't pair in the Roamio. Wonder if a high SNR like that can be a factor.
I don't have an attenuator but I have a four-way splitter. That dropped the signal down to the 80s on some channels, high 90s on others. SNR is 33-39.
OK to leave the splitter vs. buying an attenuator?
