DELTA BNC konektor samec na BNC konektor samec rovný spojovací adaptér, 75 Ohm, poniklovaná mosadz, PTFE izolátor

For installations where two BNC cables must be joined without signal loss or bulky barrels, this DELTA BNC-W/BNC-W coupler delivers a direct, in-line connection that preserves impedance and keeps your video or RF chain tidy. Unlike generic adapters that rely on plastic bodies and loose centre contacts, this model uses a machined brass housing with nickel plating and a PTFE insulator to maintain a stable 75-ohm path from DC to 4 GHz.

Highlights

• BNC male to BNC male straight coupler for joining two BNC female cables or devices
• True 75-ohm impedance, ideal for CCTV, broadcast video, and RF test setups
• Nickel-plated brass body and contacts resist corrosion and wear over 500 mating cycles
• PTFE insulator ensures low loss and consistent performance up to 4 GHz
• Compact, tool-free installation — simply screw the BNC connectors onto each end

In daily use

This coupler is the missing link when a cable run is just a bit short or when you need to extend a patch panel connection. Because both ends are BNC male, it works directly with standard BNC female sockets found on cameras, monitors, and test instruments. The straight-through design adds minimal insertion loss, and the nickel-plated surfaces provide a secure grip without galling. In CCTV systems, it allows you to join pre-terminated cables without re-crimping, saving time on site. For RF benches, it offers a reliable way to extend measurement cables while keeping VSWR below 1.2:1 at 3 GHz.
