50 Ohm low-loss coaxial cable (MIL-C-17)

RG213/U QAXIAL – 50 Ohm low-loss coaxial cable (MIL-C-17)

The RG213/U QAXIAL coaxial cable is a 50 Ohm cable with polyethylene (PE) dielectric, designed for RF applications requiring low attenuation and a more robust construction compared to smaller-diameter cables. It is suitable for RF links and longer cable runs.

Main technical features
