TV Reception: Interference
Solving poor signal quality from external sources
Is it really interference?

If your antenna is correctly rated for your area and in good condition, but glitches persist, check for these two signs:

Intermittent Problems
Issues that come and go at specific times.
Neighbour Impact
Neighbours experiencing the same glitches simultaneously.
Quality vs. Strength

Interference affects signal quality, not strength. This is why signal boosters often fail—they amplify the unwanted "noise" and make the problem worse.

Household Electrical Appliances

Short high-energy bursts known as "impulse noise" can be emitted from devices inside or outside your home.

Electric Motors
Washing machines
Swimming pool pumps
Power tools
Thermostats
Hot water systems
Water-bed heaters
Refrigerators
Pool chlorinators
Other Items
LED lights
Smart Meters
Faulty light switches
Electric fences
Pro Tip: Identify the source by turning appliances off one by one while checking your TV screen.
Amateur & CB Radio

Faulty radio equipment or antennas that cannot reject unwanted transmissions are often the cause of "bleeding" signals.

Amplifier Overload

Masthead boosters can make your system vulnerable to high-level signals like mobile broadband (4G/5G). Always use filters in front of amplifiers.

Power Line & Street Light Issues
Environmental Sparking

Hot, dry, and windy weather causes sparking between power line insulators and metal brackets. In the evenings, dew forming on built-up dust, salt, or industrial pollution triggers the same effect.

Rain clears this interference
Street Light Timing

If interference starts exactly when street lights turn on or off—or if they flash during the day—the fixture is likely defective.

Report persistent issues to your electricity supplier.
SAFETY WARNING

Do not personally attempt to rectify any suspected faults on power poles, power lines or street lighting. Contact your local electricity supplier immediately.
