may be necessary to amplify the signal. Alarger or powered antenna may be required.
• The picture looks snowy. Asnowy picture is usually due to aweak signal. Adjust the antenna
or install an antenna amplier.
• The image is duplicated or appears fuzzy. Double images are usually caused by signal reec-
tions from tall buildings. Adjust the direction of the antenna or try to raise it.

other devices that interfere with reception. Turn o other devices in the area.
• The image has diagonal or chevron interference patterns, or parts of the image are missing.
This kind of interference is usually caused by high temperature electrothermal devices. There
