S86208 - 50 Ohm Coaxial RF Cable

S86208 is a 50 Ohm coaxial cable and the industry’s workhorse, with decades of proven performance in the aerospace and defense markets. The S86208 features a low-loss PTFE expanded tape dielectric between the center conductor and shield, which improves shielding and strength compared to conventional wire braids. S86208 is a lightweight and more compact replacement for standard M17/128-RG400 coax cable. When compared to RG400, the S86208 coax cable is two-thirds the diameter and less than half the weight — 20 lbs vs 43 lbs per 1,000 ft.

*When using in high density D38999 connectors or in fully sealed environments, please contact PIC for assistance.
