Product Overview
Pasternack PE4378 is a 50 Ohm BNC male crimp connector designed for RG213, RG215, and RG8 coaxial cables. It provides a bayonet-style quick-connect interface rated from DC to 4 GHz, with a nickel-plated brass body, PTFE dielectric, and a gold-plated center contact.

Applications
- Terminating RG213 or RG8 feed lines on amateur radio HF and VHF stations

- Makers and experimenters building RF projects that use heavier 50 Ohm coax
Frequently Asked Questions
Is this connector compatible with RG58 or LMR-400 cable?
No. The PE4378 is sized for RG213, RG215, and RG8. RG58 is too thin and LMR-400 is too large - using either will result in an improper crimp and signal leakage. For RG58, a different BNC connector model is required.
What tools do I need to install this connector?
You need a crimp tool with the correct hex die to compress the outer nickel-plated ferrule, and a soldering iron to attach the center gold pin to the cable's inner conductor.
Will this connector work in 75 Ohm systems?
No. The PE4378 is a 50 Ohm connector and is not compatible with 75 Ohm systems, which use different physical dimensions and impedance specifications.
Is the center pin pre-installed or separate?
The center pin is a separate piece. All three components - body, crimp ferrule, and center pin - are included and require assembly onto the cable.
Heavy coax deserves a connector that keeps up with it. The PE4378 was built for RG8 and RG213 runs where signal integrity from DC to 4 GHz actually matters - yours to put to work.
