The digital signals, unlike analog signals, are all or nothing signals, so once they start to degrade they pixelize, and then they progress to a black screen. In this case, there are some checks that should be done:

• Is the antenna pointed in the right direction?
• Is the antenna preamplifier, if so equipped, plugged into a working household outlet?
• Was the antenna damaged in a storm or otherwise moved?
• Have you rescanned your TV recently?

TV antennas are relatively simple devices, but even a small change in the antenna location or coax cable network could cause poor reception.
