HELIFLEX® 5-1/2" low loss air dielectric cable; flame retardant/ halogen free jacket
FEATURES / BENEFITS
Low Attenuation The low attenuation of HELIFLEX® coaxial cable results in highly efficient signal transfer in your RF system.
Complete Shielding The solid outer conductor of HELIFLEX® coaxial cable creates a continuous RFI/EMI shield that minimizes system interference.
Low VSWR Special low VSWR versions of HELIFLEX® coaxial cables contribute to low system noise.
Outstanding Intermodulation Performance HELIFLEX® coaxial cable's solid inner and outer conductors virtually eliminate intermods. Intermodulation performance is also confirmed with state-of-the-art equipment at the RFS factory.
High Power Rating Due to their low attenuation, outstanding heat transfer properties and temperature stabilized dielectric materials, HELIFLEX® cable provides safe long term operating life at high transmit power levels.
Wide Range of Application Typical areas of application are: feedlines for broadcast and terrestrial microwave antennas, wireless cellular, PCS and ESMR base stations, cabling of antenna arrays, and radio equipment interconnects.
