As I expected, the signal strength dropped as light faded into evening. Split 3, to a LCD digital TV, would have periodic drops of 0% signal strength on channels 2.1 and 2.2. 2.1 was a slightly stronger signal, in the red with a drift around 27-29% signal strength. Picture would freeze and repixilate every once in a while. Channel 2.2 was worse, at 25-27% signal strength and regular picture problems. 6.1 was pretty good and maintained a pretty close to 40% signal strength.
Split 2, to the RCA digital receiver, maintained the same antenna signal strength, but had periodic drifts dropping lower - causing both 2.1 and 2.2 to have intermittent picture problems. 6.1 was unaffected.
Split 1, to the Avermedia tuner card, had no signal change, with all 3 channels showing 4 green bars. Channels 2.1 and 6.1 had no problems, but channel 2.2 had occasional picture freeze.
So this much is now clear: reception of channels 2.1 and 2.2 diminish at night, do so to a degree to all three tuners, but seems to be worse going to the tuners with slightly longer runs from the splitter. Those two coax runs were installed by satellite guys from DirecTV so I trust cable and wall connections are properly constructed/shielded.
While I await other comments here, I am going to replace the coax cables from wall to devices, to see if this improves signal strength (or reduces interference.) I appreciate any added comments/ideas.
