NTF Cable 

Economical Low Loss Flexible Coaxial Cable

NTF series cable meets military performance requirements and combines low cost with low loss. This series cable uses a silver-plated copper center conductor, low-density PTFE tape core dielectric, AL tape outer conductor, and a UV and corrosion-resistant blue FEP outer-jacket. The series accepts standard crimp-on and solder-on connectors. It is very suited for longer cable assemblies. Typical NTF cable applications include interconnections, base stations, and wireless. It is available for fast delivery, and OEM is welcome. There is no minimum order quantity requirement.
