JEFA Tech Low Loss 400 is the most popular "workhorse" cable of the wireless LAN industry. It has a perfect balance of flexibility and low signal loss. Low Loss 400 is the most popular feed line for permanent installations. It has a 0.405 inch outside diameter and features a solid center conductor for greatest performance, foam dielectric and double shielding for low signal loss and interference rejection, combined with a direct burial capable, UV resistant Polyethylene jacket.

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.

TECHNICAL SUMMARY:

  • 50 ohm impedance
  • .405" outer diameter (same as RG-8, RG-213, LMR-400, etc)
  • Lightweight, Flexible
  • Polyethylene Jacket - provides full waterproofing and UV Protection
  • Solid Copper Clad Aluminum Center Conductor
  • Direct Burial Rated - no conduit needed
  • Double Shielded for low loss and interference rejection
  • First Shield: Bonded aluminum foil with 100% coverage
  • Second Shield: Tinned copper braid with 98% coverage
  • Foam Dieletric - adds to flexibility and performance
  • 5 year warranty, 20+ year life expectancy
  • Uses same size connectors as RG-8, RG-213, LMR-400 size cable, including standard PL-259's
