Can anyone point me to the previous thread about receiving OTA HD in my area. I think there was an antenna site that had lots of info on the type of antenna you need by your zip code to receive your OTA HD broadcasts. I want an antenna that can be located in the attic (or somewhere other than outside; my subdivision has restrictions against this !) Can anyone give me some info? Any help will be greatly appreciated. Just received my 811 & cannot receive anything other than the big 4. No CBS available in my area again! Tried a small indoor "rabbit ear" amplified unit from Radio Shack to no avail.
