The most common types of television interference are as follows.
IGNITION

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.

necessary to install a stronger aerial to improve the picture.
