RG402 Semi-flexible Teflon Coaxial Cable

Semi-Flexible cable, also known as hand- formable cable, combined with semi-rigid and flexible coaxial cable, it is the same size as standard semi-rigid cable, but more flexible, thus enabling use of all of the same connectors and tooling, but offers an even more flexible alternative.

The attenuation is low even at high frequency (HF)


  • Good flexibility, Hand forming without tooling,
  • Available in long lengths,
  • Standard connectors for semi-rigid cable can be utilized.
  • Conductor: SC
  • Dielectric : PTFE
  • Shielding: Tin Immersion
  • Jacket: FEP (blue)
