Super Low Loss - LCU400
LCU400 is a 50Ω 10.3mm diameter super low loss coaxial cable, designed for high frequency microwave, radar, GPS, UHF, and cellular communications.
High grade 400 series cables, like LCU400, have a tough weatherproof UV resistant thermoplastic elastomer (TPE) jacket and a service life in excess of 20 years. APA tape and tinned copper braid provide LCU400 with RF shielding in excess of 90dB, and a 2.74mm stranded bare copper core provides a low capacitance and high conductance.
dB-FLEX is Telco's 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.
