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.
Usage
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 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.
