Why does channel 7 keep breaking up?
If your TV picture is breaking up, cutting in and out, or pixelating (looks like everything is a bunch of squares), then you probably are experiencing a weak signal. Check all of the connections from the wall to your cable box and from the cable box to your TV to ensure that all connections are tight.
How do I check signal strength with TV channels?
Connect your television to the socket on your antenna signal meter marked “TV”. Turn your antenna signal meter ON, and tune-in the lowest broadcast channel for your area. Slowly rotate your antenna 360 degrees and stop at the highest antenna signal strength (usually indicated by LEDs).
Why does channel 7 pixelated?
It is caused by the transmitted signal travelling to the listener’s radio receiver by more than one path. This is usually caused by the signal being reflected off hills or tall buildings. Because the reflected signal has travelled further, it arrives at the receiving antenna a moment later than the direct signal.
