In some circumstances, all of these steps are required!Īs with 4G, 5G is starting to rollout across Sydney and with it comes more frequencies being used for mobile phone reception. Other methods that may be required to reduce 4G interference are to either install a new antenna with an in-built 4G filter, or to add a stand-alone (or multiple) 4G filters. ![]() However, older TV antenna boosters or cheap versions found at DIY shops may still not have a 4G filter at all, or sometimes a very low quality one that may not be strong enough (depending how close you are to the mobile phone towers!). The better quality quality TV antenna boosters will have a 4G filter built-in, so that the booster will not amplify those unwanted signals. If this occurs, it is bad news for your TV tuner (and you) as it will result in ‘noise’ and probably a loss of picture and sound on your TV. ![]() Unfortunately, many TV antenna boosters are not smart enough to pick out only the TV signals and will boost a wide range of signals (frequencies), including 4G frequencies. The TV signals are all we are after, not mobile phone radiowaves!ĤG interference (or LTE interference) occurs when a TV tuner receives strong 4G signals and stops the TV tuner from being able to do its job. Interference is basically when there are unwanted radio signals that are being received by a TV tuner, which confuses it or creates ‘noise’ so it is difficult for the TV tuner to grab only the TV signals. The most common problem we come across when a TV antenna booster is installed incorrectly is interference. Ideally, there should be no barrel joiners in any installation, however, sometimes this is simply not feasible Too many cable terminations: if there are too any ‘cuts and joins’ in a cable run, it can start to impact the signal strength.Poor quality cable: using high quality quad shield RG6 or RG11 cable will result in a lower signal attenuation (signal strength loss) as compared to older style tri-shield, ‘air-core’ or ribbon cabling.Long cables runs can result in a significant loss in signal strength Long cable runs: as a TV signal runs down the cable, it gradually loses signal.If you are splitting one antenna to serve 3, 4 or 8 TV outlets, then there is going to be a decrease in signal strength TV splitters: each time you split the incoming TV signal, the signal strength almost halves.Low Gain antenna: you have a low gain antenna that only provides for a low signal strength.Poor incoming signal: there are objects blocking the line of sight (or RF interference), interrupting the signals travelling from the TV transmitter to your TV antenna. ![]() Poor signal area: you are located too far from the TV transmitter.The most common reasons are for low signal strength are: Your signal strength may be low for a number of reasons. That means no Channel 9 news or Friday Night Footy…. If that signal strength is too low, then your TV tuner will not be able to understand what data is being sent and so it won’t be able to convert that signal into a picture or sound. In any TV antenna system (or any RF system for that matter), there needs to be a certain level of signal strength at your TV tuner. They have been around for a long time and are a tried and tested way to increase signal strength. Yes, TV antenna boosters (also called TV antenna amplifiers) do work.
