Construction & Performance
The RFN-3629-L400 is precision sized for 400-series coaxial cable and uses a crimp ferrule to provide secure retention of the cable braid and outer jacket. The PTFE dielectric provides stable insulation characteristics, while the silver-plated machined-brass construction offers excellent conductivity and corrosion resistance.
When correctly installed with the appropriate cable-preparation dimensions and crimp tooling, the connector provides a durable RF termination suitable for professional coaxial cable assemblies.
Important Compatibility Note
This connector is specifically intended for LMR-400 and dimensionally compatible 0.405-inch coaxial cables. Although RG-8, RG-213, and Belden 9913 are commonly grouped with 400-series cables, cable dimensions can vary by manufacturer; verify the cable's actual outside diameter, dielectric dimensions, and connector compatibility before installation.
