The 89259-BLK-100 is a 75 Ohm, plenum-rated RG-59/U coaxial cable provided in a 100-foot length. It is constructed with a 22 AWG (7x30) stranded bare copper conductor, foam Fluorinated Ethylene Propylene (FFEP) insulation, and a bare copper braid shield that provides 95% coverage. The cable is protected by a durable FEP outer jacket, allowing it to operate across a wide temperature range from -70°C to +200°C. With a nominal capacitance of 17.3 pF/ft and a CMP plenum rating, this cable is well-suited for outdoor, burial, and in-plenum installations requiring high-temperature resistance and reliable signal transmission.
