It is suitable for mobile communication and radio communication antenna feeder and ground base station antenna jumper, computer room feeder and antenna connection line, military data information transmission line, etc.
1. The inner conductor adopts copper-clad aluminium wire or solid oxygen-free copper wire, which has lower attenuation impedance and better conduction.

2. The outer conductor is wrapped with aluminium-plastic composite tape and braided with tin-plated copper wire in high density to isolate clutter signal interference.

3. Nitrogen-injected foamed polyethylene insulation, 50 ohm characteristic impedance, operating frequency range: 100-3600 MHZ

4. Antioxidant high-quality PVC sheath, wear resistance, anti-interference, more flexible, environmental protection material, in line with ROHS standards.
