N Female Connector for 1/4" Coaxial Cable, OMNI FIT™ Premium,
Straight, threaded gasket and 360° compression sealing

OMNI FIT™ high performance connectors are designed for use with both CELLFLEX® (copper) and CELLFLEX® Lite (aluminium) cables. They are designed specifically to provide the highest quality connector-cable interface while simplifying and speeding up connector attachment.
All RFS connectors are fully tested for mechanical and electrical compliance to industry specifications.
The N connector meets all technical requirements and covers high frequencies as well as legacy applications. Sealing against outer conductor and jacket by means of threaded gasket and 360° compression fit. Multifunctional, self-lubricating HighTech polymer assembly locks on cable corrugation, avoids electrochemical potential differences and compression-fits to the jacket.;


  • Ultra high PIM performance i.e. reduced interference leading to high customer satisfaction
  • Two-piece design i.e. visual inspection of interlocking leads to improved installation security
  • OMNI FIT™ concept i.e. streamlined order management and reduced stock level
  • Watertight sealing in mated and unmated condition, i.e. reduced efforts during installation and improved security during operation
  • Unique NiTin plating i.e. extreme resistance against corrosion even under hardest climatic and environmental circumstances
  • Multi-thread (Tristart) design i.e. simplified and accelerated tightening process
  • RoHS (EU) and CRoHS (China) compliant i.e. can be used on a global basis
