6.1 PROBLEMS OF PICTURE
The most common types of picture problems are as follows:
IGNITION
GHOSTS
Ghosts are caused by the television signal following two paths. One is the direct path,
the other is reflected from tall buildings, hills, or other objects. Changing the direction
or position of the antenna may improve the reception.
SNOW
If the antenna is located in the fringe area of a television signal where the signal is weak,
the picture may be marred by dots. When the signal is extremely weak, it may me nece-
ssary to install a special antenna to improve the reception.
