![]() Take a look at the following symptoms on your cable TV. Symptoms of Coaxial Cable ProblemsĬoaxial cables convey signals from the external or source cable system from the provider to the different TVs in the house. Severe tarnishing of the outer surface is one of the signs that you should replace them with new ones. The cable performance will drop if the solder is weak or loose.īesides, clean silver-plated connectors often because they are prone to oxidation. Damage can arise from an improperly center pin. ![]() N and BNC are the two most common connectors at the ends of the coaxial cable. In addition, exposing the coaxial cables to low heat for an extended period of time will reduce the insulator’s shielding capabilities.īased on those facts, make sure they are a safe distance from stage lights, heat signs, hot sun, and other common sources of heat in your premises. When exposed to high as 150 degrees, the material will become soft thereby exposing the inner copper conductor to other forms of damage. Heat-related problems arise because the two plastics have a low melting point. The two main insulators used to make coaxial cables are polyvinyl chloride and polyethylene. Needless to say, you should never submerge a coaxial cable even if it’s brand new or branded “top quality”. Make sure that you cover outdoor connectors to avoid this form of damageĮven the smallest cracks on the outer surface of the cable can allow water to penetrate into the inner semiconductor. The water affects the cable’s ability to transfer data thereby making it useless. For example, during installation, the bend radius and the space between the shield and inner conductor should be even throughout the entire length.Ĭonsistent application of pressure on light foot traffic areas, crimping, improper rolling, and aging are other causes of physical damage. Physical damage arises from improper or exertion of too much pressure on the cable during installation. Let us look at the common reasons why coaxial cables go bad.
