30m LCU400 Super Low Loss Coaxial Cable

Key Features

• LCU400 50Ω series cabling


• SMA Male (plug) to SMA Female (jack)


• dB-FLEX.

Introducing dB-FLEX

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

• Telco LCU400 dB-FLEX has 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).

A heads up!

• Emergency stock fulfilment may use standard LMR-400 cable

• If you specifically require dB-FLEX cable please advise us when placing your order.

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.
