CELLFLEX® 1/2" low loss flexible cable; flame retardant/ halogen free jacket

Feature / Benefits

Low Attenuation
The low attenuation of CELLFLEX^® coaxial cable results in highly efficient signal transferin your RF system.

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.
