1-5/8" low loss air dielectric cable

FEATURES / BENEFITS

Low Attenuation
The low attenuation of air dielectric coaxial cable results in highly efficient signal transfer in your RF system.
Complete Shielding
The solid outer conductor of air dielectric coaxial cable creates a continuous RFI/EMI shield that minimizes system interference.
Low VSWR
Special low VSWR versions of air dielectric coaxial cables contribute to low system noise.
Outstanding Intermodulation Performance
Air dielectric 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, air dielectric coaxial 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.
