Are you going by the strength meters or some other measurement...because I have a very similar switch setup, and I actually get virtually the same strength on both boxes. I also noticed an HR20 increase on 1 of my OTA channels after about 30 minutes of operation - it has not changed since that time...its like the guide rebuild was delaying the channel sync-up...thekochs said:I have a switch that my H20 and HR20 feed through so I can go back and forth to view both OTAs. My OTA antenna comes in directly and has a high quality splitter to both these settop inputs. The H20 drives about 20% better reception on average over a exact channel-channel comparison.
I'm hoping D* used the same tuners (vendor, etc.) and it is just firmware tweeks to increase receive sensitivity on the HR20 but there is most definitely a difference that is noticable enough that some channels tune and others don't.
Hope this helps.
