1-5/8" EIA Connector for 1-5/8" Coaxial Cable, RAPID FIT™ Sealing compound

Rev : D | Rev date : 27 May 2024

Radio Frequency Systems’ line of high performance coaxial cable connectors are designed specifically to provide the highest quality connector-cable interface while simplifying and speeding up the attachment of connectors to CELLFLEX® coaxial cables. RFS connectors are fully tested for mechanical and electrical compliance specifications. They are available in all popular cable sizes in a variety of mating interfaces. To join two cables with EIA connectors, two identical socket connectors are installed on either end of the cables to be joined, and a coupling element is used to make the connection of the center conductor. The coupling element must be ordered separately with the exception of the S-Line male versions that have a captivated coupling element. Connectors are available in sizes matching the nominal cable size. EIA connectors provide optimal power handling for the complete transmission line system.


  • Single-piece design for Fast and Easy Installation
    Reliable and simple attachment avoids unnecessary connector adjustments and provides outstanding performance every time. Saves time and provides cost savings.
  • Robust Mechanical Design
    Low and consistent intermodulation performance guarantees outstanding system sensitivity.
  • Excellent Electrical Performance
    Consistent and repeatable low VSWR improves overall system performance and margin and reduces mismatch losses
  • Totally Waterproof according to IP 68
    Assures safe, long term operation in the harshest of Environments.
  • RoHS (EU) and CRoHS (China) compliant i.e. can be used on a global basis
