Armored LL142 Series Coaxial Cables

Crystek has ruggedized its LL142 series low-loss RF cable assemblies by incorporating spiraled stainless steel casings along with extra fortification provided by heavy-duty adhesive strain reliefs with Neoprene jackets. These added measures of protection eliminate failures commonly caused by cable flexion and compression. At 18 GHz, the new armored LL142 series assemblies feature attenuation of 0.36 dB/ft. and VSWR characteristics of <1.3.

These cables offer shielding effectiveness greater than -110 dB with an operating temperature range of -55°C to 85°C. Additionally, they feature rugged stainless steel solder clamp construction and a minimum bend radius of 1.5 in. with minimal spring-back. Armored LL142 series cables are available in four standard lengths of 24, 36, 48, and 60 inches with SMA male to SMA male connectors.
