What is the best OTA antenna at the best price out there? I currently have the Directv locals package but Directv doesn't broadcast them in HD. I know for a fact my local CBS broadcasts in HD and I'm tired of seeing the black bars on each side of the screen. My understanding is, setting up an OTA antenna will give me not only HD images, but also a full screen as does my current HD channels do now. Kinda new to all this. Sorry. Any help or tips would be appreciated. Also, how does the guide incorporate the OTA locals with the ones in my locals package? Thanks.
