RECEPTION OF INTERFERENCE
The most common types of television interference are as follows.
IGNITION
Black spots and horizontal streaks may appear, the picture
may flutter or drift. This is usually caused by interference
from car ignition system, neon lamps, electric drills or other
electrical appliances.
GHOSTING
Ghosting is caused by the TV signal following two paths. One
is the direct path and the other is reflected from tall buildings,
hills or similar obstruction. Changing the direction and/or
position of the aerial may improve reception.
SNOW
If your TV is located on the fringe area of a TV station, where
the signal is weak, your picture may be affected by the
appearance of small dots (SNOW). It may be necessary to
install a stronger aerial to improve the picture.
RADIO FREQUENCY INTERFERENCE
This kind of interference produces moving ripples or diagonal
streaks and in some cases loss of contrast in the picture.
