All the others are crystal clear and all share the same ant line.

If all the sets were exhibiting it with a weak signal then it makes me think it is an RF interference issue. Are there any local DTV carriers (beware 'virtual' channels that report a different channel number than their actual carrier) on or adjacent to the channel your using? If you nix the RF amp and hook up a CRT TV from the 80's-00's does it display the same symptoms?
