Australia switched off its analogue TV broadcasts back in 2013. Every free-to-air channel in the country now transmits exclusively in digital format.
Yet a surprising number of Australian homes are still using the same antenna that was installed during the analogue era, sometimes decades ago.
If your antenna predates the digital switchover, you might be wondering whether it still works, whether you're missing out on channels, and whether it's worth upgrading.
📋 In This Guide You'll Learn
- ✅ The difference between analogue and digital broadcasting
- ✅ Whether your old antenna can still receive digital signals
- ✅ Signs you need to upgrade and what's involved
Analogue vs Digital: What Actually Changed?
When Australia moved from analogue to digital broadcasting, the type of signal being transmitted changed fundamentally. Analogue signals were continuous radio waves that produced a picture and sound directly.
Digital signals are encoded data streams, essentially your TV station broadcasts compressed video and audio data that your TV decodes and displays.
The key difference for antenna users is that digital signals are much more efficient. They can carry more information in less bandwidth, which is why the switch to digital freed up radio spectrum for mobile phone networks.
Can an Old Analogue Antenna Receive Digital Signals?
Yes, it can, to a point. An analogue antenna receives radio signals in the VHF and UHF frequency bands, and digital TV broadcasts use those same bands. So in a technical sense, your old antenna is still capable of picking up digital channels.
However, there are some important caveats:
- →Analogue antennas weren't optimised for the specific frequencies used by digital broadcasts
- →An antenna from the 1990s or earlier has endured decades of Australian weather, with significant deterioration
- →Older antennas don't have any filtering for 4G or 5G mobile signals
- →The cabling connected to older antennas is almost certainly not quad-shield RG6, the current Australian standard
The result is that many homes with old analogue antennas experience intermittent reception problems. Some channels come in clearly while others pixelate or drop out entirely.
What Makes a Digital Antenna Different?
A modern digital antenna is designed specifically for the frequency bands and signal characteristics of Australia's digital TV broadcasts.
- →Higher gain, meaning it captures more signal energy and delivers a stronger signal to your TV
- →Frequency response optimised for digital broadcast bands
- →Modern materials: UV-stabilised plastics, corrosion-resistant metals, and sealed connections
- →Many models include built-in 4G/5G filtering to reject mobile interference
- →Designed to work with quad-shield RG6 cabling for maximum signal integrity
Good to Know
A well-chosen digital antenna, properly installed and aligned, will pull in every available free-to-air channel at your location with a clean, stable signal.
Signs You Need to Upgrade
If you're experiencing any of the following, your old antenna is likely the cause:
- →Some channels come in fine but others are unreliable
- →The picture pixelates during bad weather but your neighbours with newer antennas are unaffected
- →You've lost channels that you used to receive
- →Your TV takes a long time to find signal when you first turn it on
- →You can't receive all the digital multi-channels (like 7TWO, 9Gem, or SBS Food)
- →Your antenna has visible damage: broken elements, rust, or a leaning mount
If your antenna is more than 15 years old and you're having any reception issues at all, upgrading to a modern digital antenna will almost certainly fix them.
What Does an Upgrade Involve?
A digital antenna upgrade typically involves:
- →Removing the old antenna and mounting hardware from your roof
- →Installing a new digital antenna on a secure mount at the optimal height and position
- →Aligning the new antenna precisely toward the best broadcast tower for your location
- →Running new quad-shield RG6 coaxial cable if the existing cable is old or substandard
- →Installing a 4G/5G filter if there's mobile interference in your area
- →Connecting and testing every TV outlet in your home
- →Retuning your TVs to pick up all available channels
The whole process usually takes one to two hours for a standard home. A professional installer will use a signal meter to verify reception quality at every step.
What Channels Will You Get?
With a properly installed digital antenna, you'll receive all free-to-air channels available in your area. In most Australian capital cities and major regional centres, this includes the main channels (ABC, SBS, Seven, Nine, Ten) plus all their multi-channel offshoots, typically around 20 to 30 individual channels in total.
These channels are completely free. There's no subscription, no monthly fee, and no internet connection required.
Is It Worth the Investment?
A professional digital antenna installation is a one-time cost that provides reliable service for 10 to 15 years.
If you're currently putting up with patchy reception from an old analogue antenna, the improvement will be immediately noticeable. Clean pictures, reliable sound, and every available channel.
