4.3-10 Male Premium Connector for 1/4" Coaxial Cable, Straight,

Rev : A | Rev date : 06 May 2024
OMNI FIT™ high performance connectors are designed for CELLFLEX®  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 4.3-10 connector is an innovative, space-saving RF connection meeting all requirements even under the most severe environmental conditions and not relying on coupling nut torque. Sealing against outer conductor and jacket by means of the o-ring 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
  • Tri metal alloy 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
