FastLine
FastLine, COM-TECH proprietary Rigid Line system for indoor applications, comprehends a complete range of connections and components from 7/8’’ to 6+1/8’’, fully compliant with EIA and JEITA standards:

  • Rigid Lines: 2m or 4m line lengths
  • Elbows: with quick Plug or Flanged connections
  • Junctions: quick direct connections between Rigid Lines
  • Flanges: with extra threads for direct connection without using nuts
  • Inner Connections: to connect Flanges
  • Inner Supports: to support the inner conductor of the rigid line

Different Cutbacks (offset between the outer and inner conductor) are available:

  • Flush (Zero) Cutback, for convenient and simple installations
  • Recessed (Offset) Cutbacks, for compatibility with NAX/WX and legacy standards

Two different types of connections are available:

  • COM-TECH Socket-Plug system for more compact, more efficient, faster and cheaper connections
  • Traditional Flanged connections for full compatibility with all EIA systems

Choice of Materials
FastLine has been developed with an innovative choice of materials:

  • Inner conductor: Highly Conductive ETP Copper for low losses (as the Insertion Losses depends mainly on the inner conductor)
  • Outer conductor: Highly Conductive Hardened Aluminum, for better mechanical properties (flexibility, and lightness) and cost reduction
  • Optimal temperature compensation between Outer and Inner conductors: the highest temperature of the inner conductor is compensated by the lower coefficient of expansion of Copper
  • Full galvanic compatibility between metals, as Copper is matched to Copper (or compatible metal, as silver plated copper alloy), whereas Aluminum is connected to Aluminum
