Television: Check the Signal Quality

Digital signals can still be susceptible to interference, so even if you live in a strong signal area, adverse weather conditions can affect your signal quality. You may experience small glitches in the picture or more obvious signs where the picture is deteriorating. 

When you perform the initial setup of your TV, it is important to make sure that you are receiving the correct TV signal from your local TV transmitter by making the correct regional selection. Otherwise, you may experience missing channels or find that you cannot view certain programmes due to a weak signal. 

To check the signal quality of a channel, first select a channel which seems to have a weak signal or interference . Then follow these steps to analyse the results for the selected channel:

When analysing the Signal Information, it is important to note that Signal Quality is more important than Signal Strength.

Aerial Splitters

These allow two TVs to operate from the same aerial but reduce the strength of the signal available to the TV. 

Signal Boosters/Amplifiers

These devices can work well but some amplify everything, including noise and interference, it is better to ensure that your aerial is correctly installed and aligned first, before relying on an amplifier.
