“Many antennas come with a cheap RG59 coaxial cable that will kill your signal. If you are using a flimsy coaxial cable (the cord that screws into your TV from an antenna or most cable boxes), or if your antenna has a low-quality cable built into, it could lead to problems with your reception. Another option is to add an EMI filter, sometimes called ferrite beads or ferrite chokes, at the input/output of the transformer. The easiest way to fix this issue is to replace the lights with name-brand, high-quality LEDs that meet all emission standards. These pulses have a frequency that can interfere with broadcast transmissions and TV reception. Controlled bursts of power called pulse width modulation are sometimes used to control the brightness of LED lighting. Interference can occur when an LED light bulb or globe, a ballast or a transformer is emitting electromagnetic energy. Some LED light bulbs can interfere with your television’s OTA reception. If not, you can try to avoid using them while you’re watching television. Once you determine which item is triggering the issue, check to make sure the device doesn’t have faulty wiring or other issues that need repair or replacement. For instance, frozen images or intermittent audio can be caused by appliances and other devices in your home, like the washer and dryer, power tools or garage-door openers. You might be surprised to discover how many everyday objects in your house can interfere with OTA antenna reception. But if those don’t seem to be an issue and you are still struggling with fuzzy images, channels going in and out or other types of interference, it could be something you haven’t considered.įollowing are several potential sources of OTA antenna interference as well as tips on how to resolve the issue. There are some common obstacles that can interfere with your over-the-air antenna reception, such as mountains, large buildings or being too far away from the broadcast tower.
