Your TV antenna's direction matters more than almost any other factor in determining your reception quality.
A perfectly good antenna pointed the wrong way will give you terrible results, while even a modest antenna aimed precisely at the right tower will deliver clean, reliable free-to-air TV.
Here's how to figure out where your antenna should be pointing and what to do if your current setup isn't aimed correctly.

Why Direction Matters So Much
TV antennas are directional by design. They're built to receive the strongest signal from one specific direction while rejecting interference from other directions.
The horizontal rods on your antenna (called elements) are arranged so that the antenna has maximum sensitivity along one axis. When that axis points directly at a broadcast tower, the antenna captures the most signal possible.
Rotate it even 10 to 15 degrees off target and the signal can drop significantly. With digital TV, that drop can be the difference between a perfect picture and no picture at all.
Finding Your Nearest Broadcast Tower
Every region in Australia is served by one or more broadcast towers (also called transmitters). The tower that gives you the best signal depends on your specific location, not just your suburb or city.
Good to Know
The best tool for this is ACMA's mySwitch website. Go to myswitch.digitalready.gov.au and enter your address. The site will show you which broadcast towers serve your area, what frequencies they transmit on, what type of antenna you need (VHF or UHF), which direction your antenna should point, and whether your area has good, moderate, or poor coverage.
VHF vs UHF: Different Towers, Different Antennas
In most Australian capital cities, the main free-to-air channels broadcast on VHF frequencies, while some additional channels and regional services use UHF. Some areas are served entirely by UHF transmitters.
This matters because VHF and UHF antennas look different and are optimised for different frequency ranges. A VHF antenna has longer elements, while a UHF antenna has shorter, more closely spaced elements.
For example, in Sydney, the main transmitter at Artarmon broadcasts on VHF, so most Sydney homes need a VHF antenna pointed roughly north toward Artarmon.
In Melbourne, the main transmitter is at Mount Dandenong, which broadcasts on both VHF and UHF. The direction you need to point depends on which side of the city you're on.
How to Check Your Current Antenna Direction
If you suspect your antenna is pointed the wrong way, you can do a basic check from the ground.
Stand in your yard and look up at the antenna. The "front" of the antenna, the direction it receives best, is the end with the shortest elements or the end that points away from the mounting mast.
Now, use a compass app on your phone to check which direction the front of your antenna is facing. Compare this to the direction recommended by mySwitch for your address.
Common Mistake
Keep in mind that this is a rough check only. The precise alignment needed for optimal digital reception requires a signal meter to fine-tune.
What Can Cause an Antenna to Move
Antennas don't usually move on their own, but several things can shift them over time:
- →Strong winds and storms, especially if the mounting bracket has loosened with age
- →Heavy birds, particularly cockatoos and other large parrots, regularly perching on antennas
- →Building work, tree growth, or new construction between your home and the tower
Can You Realign an Antenna Yourself?
Technically, yes, but it involves getting on your roof, which carries real safety risks.
If you do decide to attempt it, you'll need safe roof access with proper footwear and ideally a safety harness, a compass or compass app, the direction information from mySwitch, and someone inside watching the TV to tell you when the picture improves.
The challenge is that without a signal meter, you're relying on the TV's picture quality as your only feedback. This works for gross misalignment, but it won't get you the precise aim that a signal meter provides.
When to Call a Professional
If your reception has been deteriorating gradually, if you've recently moved into a home with an existing antenna, or if a storm has knocked your antenna sideways, a professional realignment is the fastest and most reliable fix.
An antenna technician will bring a signal meter that shows exact signal strength and signal quality measurements in real time. They can aim the antenna with precision, verify the result on every TV outlet in the house, and identify any other issues during the same visit.
A realignment on its own is one of the more affordable antenna services, significantly cheaper than a full new installation, and it can make an enormous difference to your day-to-day reception quality.
