This is likely to happen if you live close to a transmitter.Īttenuators can be used to decrease the incoming signal if it is too strong without distorting it. If you are experiencing pixellation or picture break up, it may be that your signal is too strong as this often presents itself similarly to a weak signal. Some can also combine television and FM radio signals. For example, some masthead amplifiers are also distribution amplifiers. Masthead, Set-back and distribution amplifiers
#Digital antenna booster tv
These split the TV signal from a single aerial and allow the signal to be sent to several different televisions in the building. These fit between the aerial socket in the wall and your television. These fit directly under an outside aerial and usually the best type of amplifier to fix weak signals. There are three types of amplifier – masthead, set-back and distribution. To check, remove the power from the amplifier and see whether the problem goes away. This could be unwanted signals and result in picture loss on your own television and, maybe, those living nearby. For example, if water were to get into a masthead type, they can start to boost the result of the fault. Otherwise, all the unwanted signals will also be boosted, which can cause pictures to break up.Īmplifiers themselves are a common source of reception problems. A good amplifier should have a filter built in that only allows the signal you want to be boosted and not any unwanted signals. Even the best amplifier will still add some noise to the television signal it is amplifying/boosting that could result in picture break up.
A signal amplifier should only be used as a last resort when the television signal is weak.
