HELIFLEX® Air Coaxial Cable

HELIFLEX air dielectric cables consist of an inner conductor and an outer conductor. By using a dielectric helix (made of high density polyethylene) the inner conductor is centered to the outer conductor. The shape of the dielectric is either rectangular or in the case of small diameter cables, trapezoidal. Larger cables use a low material content helix with T-shaped supports. Cables for the highest power transmission use three-legged teflon spacers, which are positioned periodically along the cable.

All HELIFLEX air dielectric cables are designed to incorporate the following features:

  • High flexibility
  • High crush resistance
  • Low attenuation
  • High power rating
  • Longitudinal uniformity

HELIFLEX® cables are designed for applications where high flexibility and crush resistance are required. The attenuation of HELIFLEX® cables is much lower when compared to the foam dielectric cables. HELIFLEX® cables are used extensively worldwide for the transmission of large RF power.
