Our bulk 500-foot white RG59 75 Ohm, 18/2 (18AWG 2 conductor) Siamese/CCTV wire cables come in easy-to-use pullboxes that makes these cables easy to store, dispense and effectively organize. These Siamese coaxial/power cables provide excellent audio and video quality in both daylight and darkness, and also provide premium sound and visuals in many types of challenging environments that other, lesser quality cables would fail to capture. These RG59 Siamese cables are often used for security camera cables for their excellent recording in diverse, difficult lighting situations. The high-quality, durable PVC conductor jackets are incredibly flexible, which makes them very easy to install, and provide high-quality images when recording video evidence, or analyzing or re-analyzing an event. Our cables offer a 95 percent braided shield coverage - or a 16/8/0.12mm CCA braid - which ensures superb protection against all types of outside interference throughout the run. Shields typically combat interference and noise by either reflecting the energy, or picking up the noise and eliminating it. Whatever interference does pass through the shield is highly attenuated and does not cause interference. The coaxial cable features a 20 AWG (American Wire Gauge) 0.82mm solid bare copper center conductor. These quality materials work together to assure superior conductivity and will establish a crystal-clear signal up to 400 feet.
