I used a new cable - it didn't make a difference.
My zip is 76051.
angle up or experiment with heigth off the floor...
you should NOT have the results you are seeing ... 25 signal...with these antenna web results.

Enter your exact address on antenna web and point the bowties in that direction and follow my suggestions.
keep in mind the following...home construction materials, poor connectors, corrosion etc. can severely degrade signal
If construction materials are the issue ...aluminum siding, foil back insulation, stucco...the antenna will need to go outside for best results.
peak on analog first to get your bearings...check for ghosting (multipath) and snow (weak signal) and go from there after you check your connectors, etc. This will offer your first clues of why you are having poor performance issues on digital.
