Cable signal strength is the measure of the power of the electrical signal that is transmitted from the cable company to your home. A strong signal is important for getting a clear picture and sound on your TV, and for avoiding problems such as pixelation, freezing, and dropouts.
There are a number of things that can affect cable signal strength, including the distance from the cable company’s headend to your home, the quality of the cabling, and the presence of interference from other electronic devices. If you are experiencing problems with your cable signal, there are a few things you can do to try to boost the signal strength.
