Make sure your antenna system is up to scratch.
Most reception issues are caused by an inadequate antenna set-up, old or broken antennas and cabling, or inappropriate use of masthead amplifiers.
You should have a single antenna installed on your roof. Based on the mySwitch information (step two), check if:
your antenna is the right type for the channels of the transmitter providing your best coverage
your antenna is pointing towards the transmitter providing the best coverage
your antenna is correctly oriented so that its elements are horizontal or vertical to match V or H polarisation of the signal.
You should also check if your antenna is installed outdoors, is in good condition and is securely mounted, and if your cable needs replacing. A good quality cable can significantly improve your reception. For households with multiple television outlets, make sure the cabling to each wall outlet is done properly.
Legacy or broken antennas should be removed from the roof. If you use multiple antennas pointing to different TV transmitters, you’re likely to experience reception difficulties.
Any work on your antenna system should be done by an experienced antenna installer. Your installer should also be able to advise how to optimise your antenna system to ensure reliable reception. Go to Do I have the right antenna system? for more information.
