Do you have an amplifier installed? If so, remove it as your signals are very strong and amplifying them will cause your specific symptom (or others).
Otherwise, try the following as needed:
1. Adjust the antenna so that it is aimed with the bowties (whiskers) so they are perpendicular to the direction of South Mountain.
2. Raise or lower the antenna in 12" increments, if possible.
3. Move the antenna and try again. Do not drill any new holes until you've found a spot where the signals cooperate with the antenna.
If your TV set has a signal meter function, try to observe (and then report) how it behaves when you have that pixelization.
