I feel for folks farther out and the quality of the reception you may/may not be getting. I wasn't bragging about MY signal, just offering it as a relative point. For years (2003-2006) I was tuning HDTV on my Samsung TS-160 and never got anything greater than a 77% for WAFF on it's signal meter. Then DirecTV offered me an HR-20 and that had its values in the low 80's on the same antenna distribution (from my attic). The point I'm making is there has been a recent shift in the direction of goodness at WAFF. If ours locally is better this should indicate an upward trend for those farther out. Also, that none of these manufacturers use any kind of absolute scale - unlike the last poster who has a dB (measured) signal.
BTW I have an ATi HDTV-Wonder, AVerMedia Duet, Hauppauge HVR-1600, ATi 650 USB Combo, and a HDHomeRun for a total of 7 tuners acorss 5 assemblies and 4 manufacturers - they all report differently and depending on the software/drivers I may or may not get anything more than a bar graph indication... is that strength, quality, or? Again, it's just a relative point, not meaning to brag. Besides, at 9.8 miles from the towers in Monrovia and the years of tweaking I should be getting an excellent signal!
