RL158-50
1-5/8" Flanged Rigid Line

Rev : 02 | Rev date : 11 Aug 2022

RFS manufactures a range of unflanged and flanged rigid coaxial transmission lines and accessories to meet all commonly used EIA/IEC standards from 1-5/8" to 8-3/16".
1-5/8" flanged rigid line is a rigid coaxial transmission line, ideal for outdoor or indoor connections between RF broadcasting equipment.

 

FEATURES / BENEFITS

  • Inner and outer conductors are made from the highest purity copper (99.95% for inner, 99.9% for outer) for minimum attenuation and lowest operating temperature.
  • Manufactured from hard drawn copper, milled to exact dimensions to ensure strict compliance with specifications and stable characteristic impedance.
  • All spacers/insulators are made from virgin PTFE for the highest physical and electrical insulation properties.
  • The outer conductor is painted for a high-quality long-lasting finish, which also aids in heat dissipation.
  • Swivel flange on one end for ease of assembly
  • Suitable for pressurised systems
