158EIA-HCA118-001
1-5/8" EIA Female Connector for 1-1/8" Coaxial Cable, Gas barrier, Sealing compound

Rev : E | Rev date : 10 Apr 2026

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 HELIFLEX® 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.;

Features / Benefits

  • Excellent gas tightness, Overpressure for increased voltage handling is maintained throughout the system

  • Robust Mechanical Design, Superior and consistent performance guarantees outstanding system characteristics.

  • Extremely low reflection factor, Outstanding low reflection factor 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. System tightness doesn't have to rely on overpressure from dehydration equipment.
  • RoHS (EU) and CRoHS (China) compliant i.e. can be used on a global basis
