Antenna Recommendation
I am considering cutting the cord and am experimenting with a HTPC set up and OTA. For the experiment, I bought a Mohu Leaf 30 (due to price and local availability) during my experimentation. The Leaf is mounted behind my TV (in a second floor room) on the slanted wall of our cathedral ceiling. I'd prefer not to raise ti so we don't have to stare at an antenna. The ceiling wall it is on is on the north face of our house near the east end of the house and is on the second story of the home. It is the house position nearest the transmitting towers. Here is the signal analysis.
The set up actually works really well, with one exception. FOX (6.1) is laggy and displays green pixelation/jitters. It has never cut out and gone black completely. That is the only station I have noticed issues with. Unfortunately, since I watch NFL, it is also an important station to fix. So I have a few questions: 1) Can someone recommend a different antenna that would work for all stations? 2) Or is the problem that I have it hidden behind the TV on a slanted wall? |
Move the antenna and try again. The "best" location would be stuck on a window that does not have energy film or a metal window screen and faces the broadcast towers without your neighbor's house, a big tree, or a forest in front of it.
Move the antenna away from the TV set as they sometimes self-interfere when the antenna is too close. The bottom line is that the antenna will tell you where it needs to be, it doesn't work the other way (where you tell it that it has to work where you want it). |

How well does the Leaf work with the TV tuner vs the HTPC tuner? Does the TV tuner or the HTPC tuner have readouts of signal strength or more important signal quality to help you position the antenna? I agree with ADTech, you must put the antenna where the best signal exists. I suspect multipath reflections and tuner overload. WTMJ has a Noise Margin of 75.1 dB. http://forum.tvfool.com/attachment.p...1&d=1436231017 Interpreting Noise Margin in the TV Fool Report http://www.aa6g.org/DTV/Reception/tvfool_nm.html You could test the overload theory by inserting an attenuator in the coax line. You can add a length of coax using an F-81 adapter to try different antenna locations. Quote:

I only tolerate them for what they can do for me. I never have understood why anyone would want to watch TV on a computer instead of a TV. I see a lot of trees in your area. See attachment 1. http://www.hdtvprimer.com/antennas/siting.html scroll down to Trees and UHF I also see that you have some strong local FM signals that might interfere with TV reception. See attachment 2. You should insert an FM filter in the coax line. http://www.mcmelectronics.com/produc...-FM-88-/33-341 http://comingsoon.radioshack.com/rad...l#.VZskAzjbJLM very slow link |

So one interesting thing. FOX is fine tonight. The two prior times I tuned in that channel, I was watching the US women's world cup. Could the contact have caused the issues?

OTA signals are constantly changing in strength.

Oh, OK. Usually the best cameras are used for sports. But, there could have been a technical problem with the network feed, especially if it was through satellite.
