5G & 4G Interference: Why Your TV Drops Out in Summer
Ever sat down on a hot January afternoon to watch the cricket, only for the screen to turn into a glitchy mess? You have checked the cables, the weather is bone-dry, and yet the signal keeps dropping out. The problem might not be your TV at all. It could be the phone in your pocket or the mobile tower down the street.
As mobile networks continue to expand across Australia, mobile network TV interference has become a common issue for many households. If your TV starts acting “on the blink” as temperatures rise, there is often an invisible signal clash happening above your roof.
The Summer Signal Struggle
So why does this problem seem worse during summer?
It comes down to a perfect storm of conditions. Warmer months mean higher mobile data usage, more people streaming outdoors, and atmospheric conditions that allow signals to travel further than usual. Together, these factors lead to summer signal interference issues, where mobile frequencies overlap with the frequencies used for digital television.
How 5G and 4G Interfere With TV Signals
In the past, TV broadcast frequencies had plenty of space to operate without disruption. That space has reduced as 4G and 5G networks have expanded closer to television signal ranges.
5G interference with TV signal
This often appears as pixelation, freezing, or channels dropping out completely. The issue is usually more noticeable during peak usage hours between 5 pm and 9 pm.
The filter problem
Many older antennas were never designed to block high-powered mobile data signals. Instead, they attempt to receive everything. This overloads the TV tuner and results in unstable reception.
4G signal causing TV dropouts
Even if you are not in a 5G coverage area yet, nearby 4G towers can overpower your antenna system. This can cause the picture to stutter, freeze, or disappear altogether.
Signs Your TV Is Affected by Mobile Interference
If you are unsure whether interference is the cause, look for these common signs:
- Selective dropouts affecting only certain channels, often ABC or SBS
- Signal problems that appear in the evening but disappear earlier in the day
- A visible mobile tower located close to your home
If these symptoms sound familiar, interference is a likely cause.
The Fix: Filters and Shielding
The good news is that most households do not need a new television. In many cases, the solution is a correctly matched 4G or 5G filter.
This small device installs into your antenna system and blocks unwanted mobile frequencies while allowing TV signals to pass through cleanly. When installed correctly, it restores stable reception without affecting channel availability.
At Mr Antenna, technicians use specialised spectrum analysers to identify the exact source of interference. This allows them to select the correct filter and ensure it works with your existing antenna setup.
Why DIY Fixes Can Be Risky
While filters are available online, choosing the wrong type can make the problem worse. An incorrect filter may block the very channels you are trying to watch.
A professional technician can assess signal strength, check amplifier gain, and confirm that your system is properly shielded. These details matter when dealing with modern mobile signals.
As part of The Mr Group, Mr Antenna provides professional antenna repairs and tuning services across Australia. This ensures your system is protected against today’s crowded signal environment and continues to perform reliably.
Do Not Let Tech Ruin the Summer
Australia has some of the best mobile networks in the world, but they should not interfere with your favourite shows. If your TV drops out during the summer, it is often caused by frequency interference rather than faulty equipment.
Addressing the issue early means you can enjoy the rest of the season without constant interruptions.
