RECEPTION PROBLEMS
• IGNITION NOISE:
Black spots or horizontal streaks may appear, picture may flutter or drift. Usually caused
by interference from automobile ignition systems, neon lamps, electrical drills and other
electrical appliances.
• GHOSTS:
Ghosts are caused by the television signal following two paths. One is the direct path and
the other is reflected from tall buildings, hills or some other objects. Changing the
direction or position of the antenna may improve reception. Ghosting may also be caused
by defects in the antenna system such as unshielded leads or connecting several sets
to the same antenna without using multiple antenna couplers.
• SNOW:
