This cable is available in Black and White, and comes in lengths from 1 foot to 200 feet (including our most popular lengths of 50 feet, 75 feet, 100 feet, 150 feet, and 200 feet). The center conductor is made of high grade copper coated steel that has been swept to 4.0GHz, making this a great application for Satellite, Cable, Wireless (including cell services), and Communication uses. With very low signal attenuation (2.75dB at 750MHz for our 50' cable) it can be used on long runs without the loss of signal or picture. We use high grade 360 degree compression connectors to ensure that this cable remains water and weather proof, without the loss of any signal. This ensures that the ends can withstand pulling, weather, extreme hot and cold (rated up to 167 degrees F). The coaxial shielding is 60% aluminum magnesium alloy braid and 100% solid aluminum foil (including an 18% overlap) to ensure that there is no interference from neighboring or rouge signals. The outer jacket is a flexible UV resistant PVC and has been tested to be used in many extreme conditions for use both inside and outside. The dielectric center is made from gas injected foam PE and has an almost perfect consistency of 75 Ohms +/-3 throughout the entire length of the coax cable. The outside diameter of the cable is 0.27 inches, about 6.85 mm, with the connectors being slightly larger at .4375 (7/16) of an inch (11.11 mm).
