Double Shielded Flexible HF400UF Coaxial Cable (LMR400UF UltraFlex equivalent) MADE IN ITALY HF400UF Coaxial cable is one of the most popular products within the coaxial cable range. The LMR400 / HF400 is recognized globally as the industry standard ultra low loss flexible low cost lightweight DC – 6GHz coaxial cable solution for many RF applications. Why choose HF400UF? HF400UF is very well know for it’s Extreme flexibility Excellent Reliability and Low attenuation. The HF400UF cable has much lower attenuation than RG 8 RG 213 RG 214 and 9913 Air-Dielectric type Cables. The HF400UF cable was created to achieve much better flexing abilities than the HF400/LMR400. This has been achieved through the use of a stranded center conductor and PVC outer jacket. This is an excellent product where extra flexure is required for installations. How is the HF400UF low loss figures achieved? This is achieved due to the cable construction specifications. The center conductor uses a high conductivity Stranded Bare copper conductor material. The dielectric is gas injected foamed Polyethylene which helps achieve 84% Velocity of Propagation. The Dielectric has a Aluminium foil outer conductor which is chemically bonded on to it. Due to the cable construction the attenuation is significantly lower as compared to single shielded coaxial cables: RF shielding of HF400UF is > 90 dB as compared to 40 dB for RG8. Outer Sheath HF400UF coaxial cable comes with a UV resistant flexible PVC Jacket. This helps allow the cable to bend with much less force than that of standard HF400 with PE or LSZH Jacket. Frequency Operating Band HF400UF is designed to operate excellent from DC up to 6GHz. For any frequency band at VHF and above HF400 series is the obvious choice. Features: Indoor/Outdoor. Flexible UV-protected black PVC jacket Stranded Pure Copper Conductor and Tinned Copper Braided Shield for best-in-class data transmission with minimal attenuation Certified for EU and UK.
