Picture defects and countermeasures (AIR reception)

The most common types of television interference are as follows:
SNOWY PICTURE
Snowy picture is usually due to weak signal. Adjust an-
tenna or install an antenna amplifier.
DOUBLE IMAGE OR "GHOSTS"
Double images are usually caused by reflections from
tall buildings. Adjust the direction of the antenna or raise
it.
RADIO WAVE INTERFERENCE
Wavy patterns are moving on the screen, which are
usually caused by nearby radio transmitters or short-
wave receiving equipment.
HIGH TEMPERATURE ELECTROTHERMAL INTER-
FERENCE
Diagonal or herringbone patterns appear on the screen
or part of picture is missing. This is probably caused by
high temperature electrothermal equipment in a nearby
hospital.
NOTE:If one of these symptoms appears on the screen
when the cable from a company is connected,
this may be due to the local cable company
broadcast.
