Snowy dots and interference

If the antenna is located in the fringe area of a

television signal where the signal is weak, the

picture may appear snowy. When the signal is

weak, it may be necessary to install a special

antenna to improve the reception.

Adjust the position and orientation of

the indoor/outdoor antenna.

Check the connection of antenna.

Fine tune the program.

Try another program. Broadcasting

failure may happen.

Ghost

“Ghosting” occurs when the television signal

follows 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.

Radio frequency interference

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.
