The 8259 010100 is a 100ft RG58A/U-type Coaxial Cable with 20AWG stranded (19 x 33) tinned copper conductor, polyethylene insulation, tinned copper braid shield (95% coverage) and black PVC jacket. This coaxial cable is perhaps the most common, basic and easy-to-understand cables. Basically, they are used to transmit electrical energy or signals, from one location to another, to connect a source to a load, such as a transmitter to an antenna. Coaxial cable (coax) is typically identified or classified according to its impedance or RG-type. Belden® coaxial cable is tested with equipment that simulates every known environmental and electrical performance condition. As a result, this cable can be counted on for positive, reliable and trouble-free operation.
