FC-Feeder-cable-RFS-7/8
Application and Properties:
RFS 7/8" feeder cable is a coaxial cable with high flexibility and its outer conductor made from corrugated copper and also its inner conductor is a copper tube. TUltra Low Attenuation of the cable results in extremly efficient signal transfer in your RF system, especially at high frequencies. VSWR of the cable contribute to low system noise. Solid inner and outer conductors of the feeder virtually eliminate intermods.

Applications :
• Main feed line
• Feedlines for broadcast and terrestrial microwave antennas, wireless cellular, PCS and ESMR base stations, cabling of antenna arrays, and radio equipment interconnects.

Other Details
• High quality and excellent performances
• Ultra Low attenuation
• Complete Shielding for minimizing system interference
• Low VSWR
• Outstanding Intermodulation Performance
• High Power Rating
