Results - some improvement, but not much. He did not get ABC to work in high def, but said the local ABC affiliate is not broadcasting in high def except for a couple of hours in the daytime and thats why I was not getting a picture. I repeatedly questioned him about this and he said he was positive that was true and that he had just been to training the day before and they told them that again during the training. After he left, I checked the signal meter under setup on the receiver and it actually shows that the signal strength was 80% even though there was no picture. On my other OTA stations, the signal strength is usually about 60% and I get picture, so maybe he was right about them not broadcasting at night right now. Can anyone in the Dallas area confirm this? I can't imagine a station not broadcasting in high def during prime time.
As for the other OTA channels, some marginal improvement. Before I probably averaged receiving any particular channel 10 percent or less of the time. When I did, it was usually on a real cloudy day. Now I am receiving any particular channel 50-60% of the time. Signal strength is usually around 60% when I am receiving. Oh and that is with the powered amplifier that I added at the receiver after he left.
Bottom line is that I still don't get great signal and I think I should be. The good news is that my waiver for CBS and Fox must have been approved because I am getting their national feeds now. I have not heard anything yet on NBC and ABC.
