JEFA Tech Low Loss 400 is a high performance alternative to CommScope® WBC-400, Times Microwave Systems LMR®-400, Belden® 9914 / 9913 / 7810 and Andrew® CNT-400 coax cable.


This is high performance coaxial cable which has become the standard of the outdoor wireless LAN industry. It is also used by Amateur Radio stations looking for higher performance for VHF/UHF, microwave, and satellite communications as compared to standard RG-8/U. It also works very well on HF, with much higher power handling capability than other coax alternatives.
