Germany RFS 1/2" SCF Feeder
Prod No.
FC-Feeder-cable-RFS-SCF-1/2
Application and Properties:
RFS 1/2" SCF feeder cable is a 1/2" Super flexible foam-dielectric coaxial cable and its outer conductor made from corrugated copper and also its inner conductor is a copper-clad aluminum wire. Low Attenuation of the cable results in highly efficient signal transfer in your RF system. VSWR of the cable contribute to low system noise. Solid inner and outer conductors of the feeder virtually eliminate intermods.

Applications :
• OEM jumpers
• Main feed transitions to equipment
• GPS lines
• Feedlines for broadcast and terrestrial microwave antennas, wireless cellular, PCS and ESMR base stations, cabling of antenna arrays, and radio equipment interconnects.
