Thank you so much for the link, I was unfamiliar with Rabbit ears
King5 (NBC)on physical 25 appears to be in its final location, this is the one we are most wanting. 31 KONG (IND) is not of major interest. Also PBS on 17 KIRO (CBS) on 24, and Komo4 (ABC) on 30 would be wonderful. I believe the last time I tried to get a signal King5 was on 48 or so, KOMO was high 30s, and KIRO was around the low 30s. I have a quad bowtie that I had up at around 35 feet, but the mount wasn't robust enough and it came loose. i wasn't having sufficient success anyway, so I took it all down. I had also tried a pair of yagis as well as trying them stand alone. Is 60 db workable? I actually had my best luck pointing to a 2000' hill behind us for the reflection. It doesn't look like my stations are yet broadcasting in ATSC 3.0, is that was you see?
