Coaxial Cabling in Pittsburgh, PA


Coaxial cable, most often known as simply ‘cable’ service (as opposed to dial-up or satellite service) is double-insulated copper wire cable used for internet and television transmission. A coaxial cable has a plastic sheath covering the entire length of the cable; a woven copper shield immediately below the plastic sheath; a plastic insulator below the sheath; and finally the actual copper wire itself below the insulator. This type of design allows data transmission in the form of a special electrical current that carries radio frequencies. There are disadvantages to this type of data transmission; for instance, the cable cannot be bent or even significantly curved without ruining the connection to the ISP provider, since the signal would then start reflecting back to the source.
