300m LCU400 Super Low Loss Coaxial Cable Spool


Key Features

  • LCU400 50Ω series cabling

  • dB-FLEX Stranded Copper Conductor

  • UV Stable rubberised TPFE Jacket.




  • dB-FLEX is our flagship subtype of LCU400 cabling, designed for maximum weather resistance and usability

  • LCU400 dB-FLEX sports a 7-strand bare copper centre conductor which permits repeated bending and much greater flexibility, allowing an incredibly tight bend radius - similar to Times Microwave's LMR-400 UltraFlex

  • Both dB-FLEX and UltraFlex cables achieve this by trading off for a marginally higher per-metre loss, up from 0.128dB/m to 0.145dB/m @ 850MHz

  • dB-FLEX has a UV-stable TPE (Thermoplastic Elastomer) jacket designed for harsh outdoor environments while maintaining maximum flexibility and minimising plastic memory (for improved wall-cavity feeding).


Importance of LCU400 Cable


  • When it comes to high frequency networks, such as 3G, 4G, WiFi and microwave band communications, cable loss becomes a big factor affecting both signal quality and strength

  • L400 series cable such as Telco LCU400 have one quarter the loss of standard grade cables like RG58, and one third the loss of LCU195 series cable

  • When used in cellular-band communications (700-2700MHz), LCU400 coaxial cable is suitable for lengths up to 30 metres. For lengths exceeding 30m please see Heliax LDF4-50A

  • Full test reports are available upon request.
