Product Description
CELLFLEX® 1/2" low loss flexible cable; flame retardant/ halogen free jacket
Application: OEM jumpers, Main feed transitions to equipment, GPS lines, Riser-rated In-Building
Features/Benefits
• Low Attenuation
The low attenuation of CELLFLEX® coaxial cable results in highly efficient signal transfer
in 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.
