I can't verify 200degrees with a compass, but I am receiving ALL the other Raleigh stations with no troubles; so that tells me the antenna aim is OK. I have coaxial and it is maybe 12-15 years old. Please don't fixate on this as the obvious problem before considering my previous posts about my TVFool chart and all the other stations I am successfully receiving, and the gain/loss coverage chart published by the station in question.

Short of installing a new antenna, how can I test this theory of "insufficient gain on low UHF"? And what channels are considered low UHF? I'm getting stations on (real) 15, 27, 28; are those low?
I did manage to call the WNCN-17 station's DTV hotline; not sure how much was hard facts vs. canned answers: "Moderate signal...we might be having some trouble in that area...we're broadcasting at reduced power...the engineers will be tweaking things over the next 6 months...rescan, rescan, rescan." I'm just gonna sit tight for now. No need for me to muck around with antennas and cables and amps and whatnot when the station's setup isn't yet finalized. I'll try to contact an engineer at the station next week.
