When people move house, it is a common issue for the previous tenant or owner to take this power supply with them as they leave.
This power supply then allows a low voltage current to be sent up the TV antenna cabling in order to provide power to the antenna booster. This power supply normally looks like a large mobile phone charger and plugs into any standard house GPO. Whilst they are ‘active’ devices, they are low voltage and are usually powered remotely via a power supply that is located internally to a house. If signal quality is insufficient, we recommend that a different antenna should be used, or the antenna should be placed at a higher point (perhaps on a higher mast) to fix the problem. Whilst it can sometimes improve signal quality, it should not be relied upon to provide any improvement to signal quality levels. They are used in situations where the incoming signal off the antenna is not sufficient in power to provide a reliable service to the TV tuner at the end of the cable. Masthead amplifiers are a type of ‘pre-amp’ and are installed directly after the TV antenna (ideally around 0.5-1.0m below the antenna’s horizontal position). Types of TV Antenna Boosters Masthead Amplifiers Installing the correct TV booster for the particular situation can provide you with TV signal strength and signal quality to guarantee you perfect digital reception. There are many different types of TV antenna boosters (the main types are masthead amplifiers and distribution amplifiers) and even more brands of TV antenna boosters, each with different quality, strengths and weaknesses.
Depending on the TV signal strength and signal quality received by your antenna, or the design of your antenna system within your premise, you may also need to install a TV antenna booster (also called a “TV antenna amplifier”).
In some circumstances, installing a high quality TV antenna (and cabling it to a TV point or multiple TV points) alone will not be enough to provide your premise with reliable TV reception.
