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.

Our coax cable is produced to strict tolerances and stored in our climate controlled warehouse in the state of Maryland, USA. JEFA Tech has been in business since 2003. We are well established and here to stay and support you with a quality product. We stand behind the quality and performance of the cable and offer a 30 day money back guarantee and five year warranty.

Trusted by many military and government customers including the HAARP (High Frequency Active Auroral Research Program) in Alaska.

5 out of 55 out of 55 out of 55 out of 55 out of 5 High Quality Cable for a Great Price, 5.31.2011
Reviewer: Adam (Portland, OR)

I've checked the resistance of the shielding and center conductor of the cable I purchased and it matches the advertised specs perfectly. I have measured low SWR readings with it as well. I have made over half a dozen cables (jumpers etc.) with it and have found no inconsistancies with the construction of the coax. The center conductor, shielding, and dielectric are always the same size. The coax does not have a nasty plastic smell to it that cheap offshore products often do and the outer vinyl sheath is thick and durable feeling in the hand, it literally feels like good stuff when working with it. I was advised to buy this coax by local CB base operators who have long runs of this cable for their antennas and they all gave good reports on this coax. In these challenging times when stretching every dollar to make ends meet is the rule I can't imagine spending twice the money on comparable cable when this high grade coax is available at affordable prices.

Reviewer: JJ (LaPorte, IN)

I use this cable to feed my 43ft Zero-Five Vertical. It is direct buried. In service about 2 years with no problems.

Reviewer: Bill (Manito, Il)

Have been using your 400 coax for a long time, 200ft. is buried to tower for over 6 years and no problem, have over 300 countries worked on 3 bands. Wouldn't have anything else. Good to see there is still such excellent quality a fair price. THANK YOU!!
