Frequently Asked Questions
What components are included in this connector kit?
This kit includes the main BNC male connector body with bayonet coupling ring, the metal crimp ferrule sleeve, and the gold-plated center conductor pin.
How is this connector assembled onto coaxial cable?
It is a standard 3-piece crimp design requiring coaxial cable stripping, soldering or crimping the center pin, and crimping the outer ferrule over the cable braid using a standard hex crimp tool.
Why buy this single connector instead of a bulk surplus lot?
You get an authentic, unused Amphenol component sealed in its factory packaging without having to purchase a surplus bag of fifty pieces. Shipping is an $8 flat rate, free once your order passes $28, and orders leave our Idaho warehouse the same or next business day.
The bayonet snap of a genuine Amphenol BNC is unmistakable. Build your cable once, lock it in, and trust the connection.
