Overview

Cablewave-RFS HCA300-50JM 3" Air-Dielectric Coaxial Cable

RFS Technologies' air dielectric cables are air filled coaxial cables which consist of an inner conductor and an outer conductor. A dielectric helix is used to center the inner conductor to the outer conductor. Air dielectric cables have low attenuation and high power rating which make them perfect choice of high RF power transmission lines, such as in FM, TV and radar systems and networks. Air cables also have better flexibility and crush resistance than other solutions such as rigid lines.

Features

  • Low Attenuation: The low attenuation of this coaxial cable results in highly efficient signal transfer in your RF system.
  • Complete Shielding: The solid outer conductor of this coaxial cable creates a continuous RFI/EMI shield that minimizes system interference.
  • Low VSWR: Standard and low VSWR versions of this coaxial cables contribute to low system noise.
  • Outstanding Intermodulation Performance: Coaxial cable's solid inner and outer conductors virtually eliminate intermods. Intermodulation performance is also guaranteed by the state-of-the-art manufacturing process at the factory.
  • High Power Rating: Low attenuation, outstanding heat transfer properties and temperature stabilized dielectric materials enable cable to provide long operating life at high transmit power levels.
  • Wide Range of Application: Air cables are good choices for telecom, broadcasting, radar and HF defense applications.
  • Reinforced Jacket to Sustain Outdoor Applications: Polyethylene is proven to be strong and reliable even in extreme environmental conditions.
