Another Jackson, MS user here. I set up my antenna for local HD about 1.5 years ago. Not much has changed as far as OTA HD broadcasting since then except for the addition of Fox on channel 41-2. Here is what I use:
VU-90 XR Radio Shack antenna mounted in attic
Zenith DTV1080 HD receiver
I live in Brandon, about 2 miles from the downtown area, and I'm about 25 miles from the farthest tower. My channels and signal strengths are as follows (note that my receiver displays a meter bar rather than a numerical readout, so I'll just post my best numerical guess):
WJTV-DT CBS HD 65-75 strength
WAPT-DT ABC HD 75-80 strength
WMPN-DT PBS HD 75-80 strength
WDBD-DT WB ED 55-65 strength
WUFX-DT FOX ED 55-65 strength
All channels come in good at anytime of the day although I do get the occasional audio and video break-ups on the CBS, WB and FOX channels, but nothing I would consider annoying or distracting. ABC comes in the best of all channels and with DD5.1 audio. All others are DD2.0 audio. I noticed WJTV was sending DD5.1 according to my receiver at one point several months ago, but I haven't noticed it since then. The WB and FOX channels are broadcasting digital only, no HD. AFAIK
the FOX channel is not even doing widescreen, since every show I've ever seen on it, including the primetime shows that are supposed to be widescreen, show up as 4x3 standard def. Hopefully, the WB and FOX channels will begin HD soon.
Does anyone know if WLBT will be doing HD when they start broadcasting digitally (finally)?
