That's true, your ABC station is high VHF ch13 and could be why you're having trouble. You're using the C2V with no pre amp correct? If you have a splitter and two TV's connected as you mentioned earlier you might try removing the splitter and connect just one TV directly to the antenna just to see if there's any improvement. With one TV connected, you could also try scanning for channels late in the evening just to see if ABC even tries to come it under more ideal atmospheric conditions.
