50 ohm 7/8" coaxial cable feature a lower VSWR, perfect shielding effectiveness, and extraordinary inter-modulation performance, these lead to fewer energy loss and outer interference. Morever, its high-performance of attenuation allows coaxial cable to be used in different RF systems, such as 3g, 4g mobile communication. And it have a wide range of applications, such as indoor distribution, broadcast, various base stations, wireless cellular, and others.
