Is Interference the Cause of Your TV Antenna Problems?

Do you experience bad TV reception even if your television has the correct antenna system and it is in perfect condition? Does the reception issue happen at random times and affects you and your neighbours at once when it actually does happen?

If so, the poor reception might be due to interference. Interference is the negative effect of unwanted signals coming from nearby devices. Technically speaking, you experience a bad signal every now and then because it is a direct result of the presence of electromagnetic energy emissions from nearby devices.

Interference doesn’t affect TV signal levels. Instead, interference affects signal quality, which signal boosters cannot help with. To fix the issue for good, it’s important that the cause of interference be identified. A qualified and skilled electrician should then be contacted for assistance.

Electrical Appliances
Impulse noise (also called short high-energy wideband noise bursts) coming from electrical appliances inside or outside the house is one of the most common causes of interference. Some appliances that emit impulse noise include power tools, washing machines, LED lights, hot water systems, and refrigerators.

Amateur or CB Radio
This device can cause reception problems if it is faulty or if its antenna installation is faulty. It is also a cause of interference if it cannot reject any unwanted transmissions.

Signal Amplifier Overload
Signal boosters such as masthead and distribution amplifiers improve the strength of any signals a television set receives. Usually, these are used in places where signal received is weak. They are also used to provide signals to many TV receivers. These usually cannot enhance signal quality and will make TV receivers susceptible to unwanted signal sources.

If it has been determined that a signal amplifier is needed, make sure to tell a professional installer to set up an amplifier that has a filter built into it. You can also ask him to set a filter at the front part of the amplifier, if applicable. Doing so should lessen the impact of broadband signals on the reception of your TV.

Street Light or Power Line Interference
If your house is near defective power lines or street lights, you can expect interference to your TV’s reception. Power line interference is also expected if a high-voltage line happens to be near your house, with the likelihood of this happening increasing during hot and dry weather, when sparking between metal brackets and insulators is most likely to happen.

During the evenings, once dew forms on pollutants that have accumulated on the power line brackets and insulators, sparking happens. When it does happen, interference happens.

As for street light interference, it happens only when the streetlight turns on or off. It also coincides with its flashing on or off during night time or daytime.

Power line and street light interference is an issue that should be reported to the power provider immediately. Never attempt to assess and fix problems with electrical poles and streetlights yourself.
