Free-to-air TV uses both VHF and UHF frequencies, and each behaves differently depending on location:

• Strong signal areas (in-town locations) often require lower-gain or filtered UHF antennas to avoid signal overload and interference.

• Weaker signal areas (out of town, semi-rural and fringe locations) benefit from higher-gain directional VHF antennas designed to capture distant signals.

• Some locations perform best with combined VHF/UHF antennas, while others require a more targeted solution.

When we arrive onsite, we assess signal levels with our Terrestrial DTV Signal Meter and select an antenna that suits your exact location. It is not a one-size-fits-all approach.

Many TV reception problems are caused by physical obstacles and electrical interference, not the antenna itself. Common issues we see locally include:

• Trees and dense vegetation absorbing or reflecting TV signals

• Large buildings and sheds blocking or bouncing signals

• Hills, valleys, and uneven terrain affecting signal paths

• Electric fences, motors, and electrical equipment creating noise and interference

• Changing conditions due to wind, growth of trees, or new buildings nearby

This is why antenna height, mounting position, and direction are critical. Simply replacing an antenna without understanding these factors often doesn’t solve the problem. We take all of this into account when deciding on your installation.

Managing 4G & 5G Mobile Interference and analogue.

With the rollout of 4G and 5G mobile networks since analogue has finished, interference has become a common cause of TV reception faults. These signals can overpower TV frequencies, resulting in:

• Pixelation and freezing

• Sudden loss of channels

• Reception that changes throughout the day

• Old TV that was analogue are no good and we have to put Digital TV antenna on the roof.

We counter this by installing quality antennas with built-in filtering, and where required, dedicated 4G/5G filters and correctly matched amplifiers, ensuring only the correct TV signals are amplified.

A reliable antenna system is only as good as its components. We use quality, proven materials throughout every installation, including:

• Heavy Duty Antennas suited to local VHF and UHF coastal conditions

• Low-loss, UV-stable coaxial cabling

• Weatherproof fittings and quality connectors

• Galvanised or stainless-steel roof mounting hardware

• Correctly rated masts, brackets, and fixings for coastal environments

• Properly matched signal amplifiers and splitters where required

Cheap cabling, fittings, or incorrectly installed amplifiers often lead to signal loss, corrosion, and repeat issues — especially in coastal areas like Hervey Bay.
