NTG Cable Structure

1. Center Conductor

2. Dielectric

3. Inner Shield

4. Outer Shield

5. Jacket

NTG series cable meets military performance requirements with high flexibility, low cost, and low loss. It uses a silver-plated copper center conductor, low-density PTFE tape core dielectric, AL tape outer conductor, and a UV and corrosion-resistant PUR outer-jacket and accepts standard crimp-on and solder-on connectors. The series is especially suited for longer cable assemblies. Typical applications include interconnections, base stations, and wireless. It is available for fast delivery as cable or finished cable assemblies with custom labeling. There is no minimum order quantity.
