TV Fool
Put in the height above ground for your antenna otherwise it defaults to 30 ft.
Look on the resulting page that probably makes no sense, but there is a bold link at the top, and just post it back here. then we can see your reception and make suggestions.
Also last I checked TV signals don't have any prejudice to Northern New Jersey, but NBC does where I live (long long story and inside joke on the forum).
