1. High-performance of attenuation allows coaxial cable to be used in different RF systems, such as 3g, 4g mobile communication.
2. Wide range of applications, such as indoor distribution, broadcast, various base stations, wireless cellular, and others.
3. Lower VSWR, perfect shielding effectiveness, and extraordinary inter-modulation performance lead to fewer energy loss and outer interference.
