The 1/2 RF coaxial cable is a rigid feeder with a 50Ω impedance. Its inner conductor is made of copper-clad aluminum wire, the outer conductor is made of circular corrugated copper tube, the insulation layer is made of physical foamed polyethylene, and the sheath is made of low-smoke, zero-halogen, flame-retardant polyolefin. Its characteristic impedance is 50±2Ω, transmission rate is 88%, and operating frequency band is 5~3000MHz, making it suitable for professional scenarios such as television broadcasting and satellite communication
