PRODUCT DATASHEET
LCF78-50JA-A0
7/8" CELLFLEX® Premium Attenuation Low-Loss Foam-Dielectric
Coaxial Cable
CELLFLEX®7/8" premium attenuation low loss flexible cable
FEATURES / BENEFITS
Ultra Low Attenuation
The further reduced attenuation of CELLFLEX® premium attenuation 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.
