7/8” Feeder Cable (Aluminum)

7/8” Feeder Cable (Aluminum)

Product Description

• The high Performance of attenuation allows co-axial cable
to be used in different RF systems, such as 3G, 4G Mobile
Communication.
• Wide range of applications, such as indoor distribution,
broadcast, various base stations wireless cellular, and others .
• Lower VSWR, perfect shielding effectiveness, and
extraordinary inter-modulation performance lead to fewer
energy loss and outer interference.
