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 Technologies 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.
