Well, let's suppose that your tuner has a low tolerance of 60% signal strength; below that, it breaks up, getting worse as it gets lower. Maybe 9 comes in borderline at 60% while 7 comes in a 65%. It's just a 5% variance, but it's on the sweet spot of failure. Not saying that's the case, but it is a possibility. You can test your signal strength per channel, usually on the TV's diagnostic tools menu. Compare those to the UHF channels. But as suggested, if you add the VHF component, you may immediately bring those levels up to say 75 & 80% each, giving you plenty of room above the 60%.....and problem solved! It's not a lock, but given the situation, it's hard to go wrong with "more" antenna.
