MULTIFLEX-L78
CELLFLEX®MULTIFLEX Jumper Assembly with low loss coax, LCF78 feeder

Rev : P2 | Rev date : 16 Sep 2021

MULTIFLEX Jumper-Cable assemblies are the simple solution for those who like to have a very low loss transmission jumper with highest flexibility at both connection ends. RFS site kitting services offers a full assembled Jumper containing feeder-cable from LCF78-50 to LCF158-50, and Jumper cable such as super flexible SCF12-50 for both endings. 

FEATURES / BENEFITS

  • Stable premium VSWR, outstanding and consistent intermodulation performance - 4.3-10 side not relying on coupling torque
    Improves network performance, reduces the number of dropped calls and avoids revenue loss.
  • Waterproof to IP 68
    No downtime risk, secures revenue.
  • Smaller connector footprint for 4.3-10
    Enables tighter spacing of connections for antennas and RRHs.
  • Available with standard ""J"" or flame retardant ""JFN"" jacket types
    Usable on global basis in all applications.
