7/8" EIA Female Connector for 7/8" Coaxial Cable, RAPID FIT™ Sealing compound

Rev : D | Rev date : 15 Nov 2025

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.

Feature / 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.
