It is usually caused by local interference, such as cars, daylight lamps
and hair driers. Adjust the antenna to minimize the interference.
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, show blocking
or break-ups. When the signal is extremely weak, it may be necessary
to install a special antenna to improve the reception.
1. Adjust the position and orientation of the indoor/outdoor
antenna.
2. Check the connection of the antenna.
3. Fine tune the channel.
4. Try another channel. Broadcasting failure may happen.
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.
This interference produces moving ripples or diagonal streaks, and
in some case, loss of contrast in the picture. Find out and remove the
radio interference source.
