Eliminate Over The Air Antenna Interference

Last updated: Monday, May 7, 2018I received an email from a reader last week with an interesting problem. Every time her friend turned on the lights in the living room she would lose 4 over the air antenna stations from her television. Once she turned off the lights the channels came back. It turns out that using certain types of LED light bulbs can cause interference with some frequencies. The LED pulses on and off at a very high frequency (beyond that which our eyes can perceive). This pulsing can create RF noise. If not shielded sufficiently, this RF noise can interfere with TV or radio signals. So I figured in this article, I would discuss what else can cause OTA antenna interference and how to eleviate it. OTA [...]

    • Are there any major obstructions; like trees or buildings in the way? It could be the type of antenna you have. Do you have a pre-amp attached to the antenna. You could try removing it and see if it helps. I have also seen with my televisions that not all tuners are build the same. One of my televisions will receive FOX better then the other. So it could be your tuner. If you have another TV with a different tuner, try plugging that one in and see if it works. Hope this helps and good luck.
