I just moved into a new home and bought the Mohu Leaf (unamplified) antenna to try out. I get great signal strength on all channels (90+), but the local FOX affiliate is horrible. It is not watchable or the most part and displays a black screen. I checked the signals in the DVR Diagnostics section and the SNR is 27-29dB. If I move the antenna to lower the signal, it pixelates as you would expect with poor signal. But when it is at a seemingly fine strength, it still does not work. The funny thing is that this is channel 9.1...and channel 9.2 seems to be fine.
It is a VHF frequency.....same as NBC which comes in perfectly. I am 13.5 miles from the towers. A mix of UHF and VHF channels work fine. FOX lies right between NBC and another channel which both are ok.
I am at a loss as to what the problem is. I will likely try a different antenna to see if that fixes it. My old house was another 7 miles away and I got by fine with a set of rabbit ears. I might have to go back to those. I am basically limited to indoor antennas....I got the Leaf because it was unobtrusive and had good feedback from other users.
Any ideas? Is it simply a signal problem and can be fixed with a different antenna? Or is it the high voltage lines that run within 100' of the house causing issues? Ghosts? What gives?
