I get SBS pretty poorly at my house. All the other channels are fine. SBS works but the sound and picture get choppy at times. I'm using my TVs inbuit HD tuner. When I look at the signal strength and quality both are quite low. Any suggestions on how to fix this? Is it a matter of pointing my antenna in the right direction or more to it than that? Can anyone recommend someone to come do this for me? I called Mr Antenna who are $75 for the callout fee and first 30minutes, then $20 per 15minutes plus parts. Which to me sounds a bit much.
