Transmission towers broadcast TV signals as radio (i.e., radio frequency) waves. These waves are strongest when they leave the transmitter and gradually dissipate as they travel over the air. It’s much like dropping a stone in a pool of water and watching the waves propagate outwards as a concentric ring whose ripple becomes gradually smaller. A TV...
Radio frequency interference is anything that degrades or disrupts your receptionof over-the-air signals. This disruption could be the result of either: 1. A physical feature or barrier degrading the strength of the radio wave (i.e., signal attenuation), or 2. A competing source that propagates signals on the same frequency as another source (i.e.,...
These types include geographic or artificial features in your environment that protrude into the path of TV signals, from mountains to tall buildings. Competing signal sources like nearby cell phone towers can also affect your television reception, if these happen to be transmitting on a frequency near that of your local television broadcast. Nearb...
Barriers like glass buildings or bodies of water can scatter a TV signal into multiple signals by reflecting these away in different directions. This type of interference is known as multipath interferencesince the smaller signals can take different paths away from the path of the original signal. Some of these signals may nonetheless find their wa...
Normal weather won’t interfere with RF signals, nor will temperatures like heat or cold, or normal amounts of precipitation. However, hot and cold days can occasionally produce high-pressure conditions that trap cold air between layers of warm air. Under the right conditions, this may cause radio signals to skip along the cold layer at much further...
Nearby cellular phone towers aren’t supposed to cause interference, but since the upper range of UHF frequencies were allocated to cell phone companies back in 2009, there have been reported cases. Someone even invented an LTE filterthat you attach to your antenna coaxial cable to minimize interference from cell phone towers broadcasting at frequen...
Your home may host various forms of electromagnetic interference, like insufficiently shielded cabling and wiring, LED lighting systems, or faulty equipment such as amplifiers. Such items have been known to interfere with TV reception. Also the very structure of your house or apartment building can make it challenging sometimes to find the right lo...
While a house is built to retain energy and keep bad weather out, it also does a terribly good job of hindering incoming TV signals. That’s why indoor antennas are manufactured with built-in amplifiers for boosting signal to noise. Depending on your home’s construction materials, your walls and roof can impede your reception up to 40-50%. Attic spa...
Any device in your home that runs on electricity will emit a subtle electromagnetic field. That’s fine in and of itself, but if you own an older home whose cabling and wiring feature insufficient shielding, use of these appliances may cause reception issues.
While you may be fairly certain of when you’re experiencing RF interference, it can be challenging to diagnose the source of the problem. Weather conditions can make your channels mysteriously disappear in the evening. Or, your screen may suddenly pixelate for no apparent reason. But understanding the source of your TV signal interference will allo...
