DescriptionLL400 Antenna Coax Cable (CLF400, KSR400,®LMR400) Super Low Loss – 50Ω Double Shielded 10.3mm*These are the cables supplied as options to our antennas. Best suited to Fixed-Wireless installations such as Office buildings and Homes. Larger than ®LMR240 but lower loss and more rigid.This version of coax is the same LL400 cable option supplied with our antenna kits and has SMA female connections on both ends. For other connectors and lengths see our Made to Order LL400 product. Double shielded by one layer of Aluminium foil and one close-knit copper braid make for a low-loss coax with 10.3mm overall diameter. Its low signal attenuation figures make it well suited for use at Cell Phone frequencies.LL400 – Signal Loss – 10m cable lengthFrequency (MHz):850900180021002400 (WiFi)Attenuation (dB):1.251.281.932.02.2Outer Diameter:10.3mm Impedance: 50ΩInner Conductor:2.74mm Solid Copper or Cu over AluminiumOuter Sheild:Bonded Aluminum Foil Tinned Copper BraidDielectric:Physical Foam Polyethylene There are many suppliers that manufacture coax cables to the ®LMR series specification.
