G'day! In the age of streaming services and internet TV, it is easy to forget that some of the best content in Australia is still broadcast entirely for free over the airwaves. From live sport on the weekends to local news and reality TV, Freeview is a staple in Aussie households. However, nothing ruins a nail-biting grand final or a movie night faster than a pixelated screen or a stuttering audio track. If your picture is breaking up, the culprit is almost certainly your tv antenna.

While the old rusty aerial on the roof might have worked back in the analogue days, modern digital signals require precision. They are an "all or nothing" technology, meaning you either get a perfect high-definition picture, or you get nothing at all. Upgrading your hardware is the most effective way to ensure your entertainment stays interruption-free.

UHF vs VHF: What is the Difference?

When you start looking for a replacement, you will notice two main types of designs: UHF and VHF. Understanding which one you need is critical, as buying the wrong tv antenna will result in zero signal.

VHF (Very High Frequency): These antennas are typically larger with longer horizontal elements. They are required in many capital cities like Sydney, Melbourne, and Brisbane to pick up channels 6 through 12 (Band 3).

UHF (Ultra High Frequency): These are generally smaller and more compact. They are used for channels 28 to 51 (Band 4 and 5) and are common in regional areas or for specific repeater stations in the cities. Many modern "combo" antennas are designed to pick up both bands, covering all bases.

Dealing with Interference

One of the biggest challenges for modern reception is the rollout of 4G and 5G mobile networks. Mobile towers operate on frequencies that sit right next to the TV broadcast spectrum. If you live near a mobile tower, your TV tuner might get overwhelmed by the stronger mobile signal, causing pixelation.

To combat this, modern antennas feature built-in LTE/4G filters. When a professional installer visits an electrical wholesaler to stock their van, they will almost always choose antennas with these filters integrated. This ensures that the antenna rejects the mobile noise and only sends the clean television signal down the cable to your lounge room.

Installation and Cabling

You can have the best tv antenna money can buy, but if it is connected with old, rotting cable, it is useless. The coaxial cable running from your roof to the wall plate acts as a shielded pipeline for the digital data.

Old RG59 cable should be replaced with modern RG6 Quad Shield cable. This heavy-duty cable has four layers of shielding to protect the signal from external interference as it travels through your roof cavity. Furthermore, the antenna needs to be mounted securely. It must be high enough to clear obstructions like the neighbour's roof or nearby gum trees, and it must be aligned perfectly with the transmission tower.

Safety First

Installing an antenna involves working at heights, often on steep or slippery surfaces. It is not a job for the faint-hearted.

While you can legally mount the hardware yourself, running cabling and terminating connections is regulated work. It is highly recommended to engage a professional installer. They have the digital field strength meters required to find the "sweet spot" on your roof where the signal is strongest and the error rate is lowest.
