G'day! There is nothing worse than sitting down to watch the footy grand final or your favourite reality show, only for the screen to freeze, stutter, and turn into a blocky mess right at the good bit. In a country as big and hilly as Australia, digital TV reception can be a bit hit and miss. If you have checked your cables and your aerial is pointing the right way but you are still getting "No Signal" messages, you might need an antenna booster.

Also known as a masthead amplifier, this little black box can be the difference between a crystal clear HD picture and a frustrating night of staring at a blank screen. However, simply slapping one on the roof isn't always the answer. You need to choose the right type for your specific location and setup.

What Does a Booster Actually Do?

Think of your TV signal like water pressure in a hose. If you live miles away from the reservoir (the transmitter tower) or you are trying to run four different sprinklers (multiple TVs) off one tap, the pressure drops to a trickle.

An antenna booster acts like a pump. It takes the weak signal coming in from the aerial and amplifies it electrically, giving it enough "push" to travel down the coaxial cable to your television tuner.

Important Note: A booster cannot fix a broken antenna or create a signal where there isn't one. If your antenna is rusted out or pointing at the ground, amplifying it will just boost the "noise" (interference), making the picture worse. It amplifies what is there, good or bad.

Types of Boosters for Aussie Homes

Masthead Amplifiers These are the most common solution for people living in "fringe" reception areas or behind hills. As the name suggests, this box sits right up on the mast, close to the antenna. It boosts the signal before it travels down the long cable into your roof, ensuring minimal quality is lost along the way.

Distribution Amplifiers If you have a strong signal coming in, but it goes weak because you have split it to feed four or five different bedrooms, you need a distribution amplifier. These usually sit in the roof cavity or behind the main TV unit. They are designed to overcome the loss caused by splitters and long cable runs within the house.

The 4G and 5G Problem

In recent years, mobile phone towers have started using frequencies that sit right next to our TV channels. This can cause massive interference.

If you buy a cheap, old-school booster, it might amplify these mobile signals along with the TV signal, causing havoc for your tuner. When sourcing equipment, a professional installer will visit an electrical wholesaler to find a modern booster with a built-in "LTE Filter." This filter blocks out the 4G and 5G noise, ensuring only the clean TV signal gets boosted.

When to Call a Professional

While you can buy boosters off the shelf, installing them correctly is a fine art.

1. Working at Heights: Climbing onto a roof is dangerous work.
2. Balancing the Signal: Too much signal is just as bad as too little. Over-boosting can overload your TV tuner, causing the exact same pixelation issues.
3. Power Injection: Masthead amps need power. This is usually sent up the coaxial cable via a "power injector" plug behind your TV. Getting this wiring wrong can short out the system.

For these reasons, it is highly recommended to engage a licensed professional. They have digital signal meters to measure the exact signal strength (dB) and adjust the booster gain to the perfect level.
