1/4" CELLFLEX Superflexible Foam-Dielectric Coaxial Cable
CELLFLEX® 1/4" superflexible cable
FEATURES / BENEFITS
• Ultra Low Attenuation
The reduced attenuation of CELLFLEX® coaxial cable results in extremly efficient signal
transfer in your RF system, especially at high frequencies.
• Complete Shielding
The solid outer conductor of CELLFLEX® coaxial cable creates a continuous RFI/EMI
shield that minimizes system interference.
• Low VSWR
Special low VSWR versions of CELLFLEX® coaxial cables contribute to low system noise.
• Outstanding Intermodulation Performance
CELLFLEX® 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, CELLFLEX® 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
