Digital (ATSC) reception in Dallas area

[kx250rider]

Although I've had decent luck with Over-The-Air digital TV in the Southern California area, I can't seem to get anything on rabbit ears in Dallas (North Dallas/Collin County area). I have cheap RCA coupon-type boxes, and the same rabbit ears I use in LA. I get one or two channels with poor reception and freeze-up, and can't get others at all.

The house is brick with an asphalt roof, and it's against the rules to have antennae on the roof higher than the highest point of the gable. We have a neighbor with a 2-story house, which blocks our southern sky (unless we put up an illegal-length mast), so DTV & Dish are poor options. Question: Will ATSC signals do OK on a roof antenna mounted in the attic, if I don't get diddly-squat in the house on rabbit ears? If so, any input on what kind of antenna?

Thanks,

Charles
